Apr 02 03:00:51 <g00s> CedricBeust are you reading anything good ?
Apr 02 03:03:02 * g00s reading "Small Data; Tiny clues that uncover huge trends"
Apr 02 03:15:35 <adq> http://imgur.com/ZsWVE3q struggling with accentcolor now... green or blue or none?
Apr 02 03:18:59 * jug6ernaut likes the green
Apr 02 03:19:05 * jug6ernaut likes green tho
Apr 02 03:19:07 <jug6ernaut> so
Apr 02 03:24:38 <adq> thx jug6ernaut, well i asked somewhere else too, none said blue atm
Apr 02 03:39:26 <g00s> yeah i think blue on grey is harder to read
Apr 02 04:40:41 <g00s> wow, Toshiba major recall (battery)
Apr 02 04:40:59 <g00s> 40 models over 2011-2016
Apr 02 04:45:02 <westj> Which is the best channel to discuss building kernels?
Apr 02 05:24:41 <teasp00n> westj: either here or android-root. for actually developing them probably here..
Apr 02 06:27:52 <westj> @teasp00n, they told me in #android-root that no-one knows in that channel...
Apr 02 06:28:14 <westj> GUess it's back to guesswork and voodoo
Apr 02 08:23:12 <Bear10> So I built launcher3 about a week ago (haven't been able to play with it too much since) and I noticed that for some reason when i power off my phone and back on, my desktop icons reverts to the default
Apr 02 08:23:24 <Bear10> all my shortcuts disappear
Apr 02 08:23:31 <Bear10> anyone have any idea about what could be causing this?
Apr 02 08:38:39 <Ashiren> this is a job for... #android (or #android-root)
Apr 02 08:56:29 <Bear10> ah ok thanks
Apr 02 10:28:34 <freelancerbob> hi, why i am getting null object from:
Apr 02 10:28:48 <freelancerbob> EditText e= (EditText) myStolenBikesFragmentAdapter.getItem(vp.getCurrentItem()).getView().findViewById(R.id.stolen_detail_bike_licence_plate_edit);
Apr 02 10:28:55 <freelancerbob> anybody know ?
Apr 02 10:29:16 <freelancerbob> everything should be ok
Apr 02 10:29:27 <freelancerbob> but is not
Apr 02 10:29:57 <freelancerbob> Attempt to invoke virtual method 'android.view.View android.support.v4.app.FragmentActivity.findViewById(int)' on a null object reference
Apr 02 10:33:57 <Napalm|afk> freelancerbob: you cant call getItem on a FragmentAdapter for a view pager.. you'll get back a new fragment
Apr 02 10:34:22 <Napalm> freelancerbob: you need to get the fragment back using its magical tag name
Apr 02 10:34:30 <Napalm> freelancerbob: then it'll have a view
Apr 02 10:36:55 <freelancerbob> where i set tag?
Apr 02 10:43:26 <freelancerbob> Napalm: how i can call fragment back using its magicaltag name ?
Apr 02 10:47:14 <Napalm> freelancerbob: open your adapter in AS
Apr 02 10:47:17 <Napalm> freelancerbob
Apr 02 10:47:36 <Napalm> : then ctrl+click/cmd+click on the class you extend
Apr 02 10:47:50 <Napalm> should be FragmentPagerAdapter or FragmentStatePagerAdapter
Apr 02 10:47:51 <Napalm> right?
Apr 02 10:48:00 <Napalm> which one you using?
Apr 02 10:48:56 <freelancerbob> Napalm: FragmentStatePagerAdapter
Apr 02 10:49:10 <Napalm> ok so your looking at the source code of FragmentStatePagerAdapter?
Apr 02 10:49:11 <Colt> Noobish question, I guess, but... If I'm using Android SDK Build-tools 23, do I need to have SDK platform 23 installed? Thanks in advance.
Apr 02 10:49:27 <freelancerbob> Napalm: yes
Apr 02 10:49:41 <Napalm> look at instantiateItem
Apr 02 10:49:58 <Napalm> see how it constructs the fragment tag name and tries to locate the current one and reuse it
Apr 02 10:50:02 <Napalm> well thats how you want to do it
Apr 02 10:50:37 <Napalm> mFragmentManager.findFragmentByTag("android:switcher:" + viewPager.getId() + ":" + viewPager.getCurrentItem());
Apr 02 10:50:41 <Napalm> see?
Apr 02 10:52:02 <Napalm> Colt: no you dont
Apr 02 10:52:13 <Napalm> freelancerbob: ?
Apr 02 10:53:01 <freelancerbob> i don't have there: mFragmentManager.findFragmentByTag("android:switcher:" + viewPager.getId() + ":" + viewPager.getCurrentItem());
Apr 02 10:54:06 <Napalm> omh
Apr 02 10:54:07 <Napalm> omg
Apr 02 10:55:01 <Napalm> are you using the FragmentStatePagerAdapter from the support library? look at the top of its source.. the package
Apr 02 10:55:25 <Napalm> if so.. you'll want to do getSupportFragmentManager().findFragmentByTag("android:switcher:" + viewPager.getId() + ":" + viewPager.getCurrentItem()); if your in the Activity
Apr 02 10:55:41 <Napalm> if not.. then just do getFragmentManager().findFragmentByTag("android:switcher:" + viewPager.getId() + ":" + viewPager.getCurrentItem());
Apr 02 10:55:49 <Napalm> and ofc, viewPager is your view pager
Apr 02 10:56:45 <freelancerbob> let me try
Apr 02 10:58:50 <freelancerbob> Napalm: Fragment f=getFragmentManager().findFragmentByTag("android:switcher:" + vp.getId() + ":" + vp.getCurrentItem());                 EditText a= (EditText) f.getView().findViewWithTag(R.id.stolen_detail_bike_licence_plate_edit);
Apr 02 10:58:56 <freelancerbob> i tried
Apr 02 10:59:18 <Napalm> f.getView().findViewWithId(R.id.stolen_detail_bike_licence_plate_edit);
Apr 02 10:59:20 <Napalm> not tag
Apr 02 11:05:36 <freelancerbob> Napalm: still same  java.lang.NullPointerException: Attempt to invoke virtual method 'android.view.View android.app.Fragment.getView()' on a null object reference
Apr 02 11:05:55 <Napalm> yes because no fragment came back
Apr 02 11:06:01 <Napalm> your using the wrong fragment manager
Apr 02 11:06:03 <Napalm> as i said
Apr 02 11:06:10 <Napalm> getSupportFragmentManager()
Apr 02 11:07:07 <freelancerbob> i tried it
Apr 02 11:07:18 <Napalm> when are you doing this?
Apr 02 11:07:22 <Napalm> during onCreate?
Apr 02 11:07:34 <freelancerbob> nope
Apr 02 11:07:58 <Napalm> freelancerbob: well when?
Apr 02 11:08:22 <freelancerbob> onOptionsItemSelected
Apr 02 11:08:38 <Napalm> right and the fragment doesnt exist
Apr 02 11:08:50 <Napalm> how many pages do you have in your viewpager?
Apr 02 11:09:03 <Napalm> you might want to check this out for reference https://github.com/xxv/android-lifecycle
Apr 02 11:09:28 <freelancerbob> Napalm: 4
Apr 02 11:10:12 <Napalm> freelancerbob: switch to a FragmentPagerAdapter instead of FragmentStatePagerAdapter
Apr 02 11:10:44 <Napalm> then call viewPager.setOffscreenPageLimit(4); where you setup your views
Apr 02 11:10:49 <Napalm> this will keep the fragments around
Apr 02 11:11:33 <freelancerbob> yes i call
Apr 02 11:11:51 <Napalm> but switch out the type of adapter you extend
Apr 02 11:16:08 <freelancerbob> Napalm: fyi: i need to call getFragmentManager().findFragmentByTag in onOptionsItemSelected because i need check all filled edittexts in my currentitem in view pager
Apr 02 11:16:58 <freelancerbob> i have next icon in my toolbar. If edittexts are not filled then you can't go next
Apr 02 11:26:58 <freelancerbob> Napalm:it is working now. Excellent thanks
Apr 02 11:27:36 <freelancerbob> Napalm: why it was not work with FragmenStatePagerAdapter ?
Apr 02 11:28:05 <Napalm> freelancerbob: thats the whole point of State version.. it doesnt keep the fragments around.
Apr 02 11:28:11 <Napalm> freelancerbob: think ebook reader
Apr 02 11:28:19 <Napalm> you dont want 500+ pages around
Apr 02 11:28:37 <Napalm> freelancerbob: so it just saves the state bundles for each fragment
Apr 02 11:32:27 <freelancerbob> Napalm: thanks
Apr 02 11:38:20 <astroduck> Hi, using GSON, how do I parse a datetime string field into long timestamp?
Apr 02 11:40:57 <Napalm> astroduck: GsonBuilder has a function setDateTimeFormat
Apr 02 11:41:13 <Napalm> same format used by SimpleDateFormat
Apr 02 11:41:17 <Napalm> https://developer.android.com/reference/java/text/SimpleDateFormat.html
Apr 02 11:41:32 <Napalm> astroduck: then just make your fields Date objects
Apr 02 11:41:40 <Napalm> thats java.util.Date not sql
Apr 02 11:42:55 <astroduck> Napalm: I know that, its already parsing it into Date object, but I want timestamp in long
Apr 02 11:43:33 <Napalm> astroduck: Date object has that.. do getTime();
Apr 02 11:44:34 <astroduck> Napalm: so GSON can't directly save it as long in my model, I'll always have to do getTime()?
Apr 02 11:45:37 <Napalm> astroduck: it can. if you write your own derserializer.. it uses the type to know how to parse it.. a long is a number.. your date string is not a number
Apr 02 11:46:53 <astroduck> Napalm: can I specify a deserializer for a specific key, not a type?
Apr 02 11:47:18 <Napalm> astroduck: did you read the instructions? https://github.com/google/gson/blob/master/UserGuide.md
Apr 02 11:49:07 <Jude999> Hello, can is somebody able to help me out?
Apr 02 11:50:21 <Napalm> astroduck: you could write a typeadapter that registers for long and then in the deserializer you check to see if the JsonElement passed in is a as string.. if it is.. then try a date decode.. else return getAsLong()
Apr 02 11:50:43 <Jude999> ??
Apr 02 11:50:55 <Napalm> Jude999: dont ask to ask.. just ask.. and see
Apr 02 11:51:06 <astroduck> Napalm: Ok, I'll try it
Apr 02 11:51:28 <Jude999> Okay I use App Inventor, you might be able to answer my question though.
Apr 02 11:51:47 <Jude999> See ---> https://groups.google.com/forum/#!category-topic/mitappinventortest/specific-programming-issue/upMDewqjpQA
Apr 02 11:52:00 <Jude999> My latest question is on there. thx.
Apr 02 11:55:27 <Jude999> So??? anybody able to help?
Apr 02 11:57:14 <Jude999> Are you here to help othere CedricBeust ?
Apr 02 11:57:34 <CedricBeust>  Not just to help, to serve
Apr 02 11:57:56 <Jude999> Okay, are you able to serve me.
Apr 02 11:58:04 <Napalm> haha
Apr 02 11:58:14 <Jude999> lol :)
Apr 02 11:58:48 <Jude999> CedricBeust: Okay I use App Inventor, you might be able to answer my question though.
Apr 02 11:58:48 <Jude999> See ---> https://groups.google.com/forum/#!category-topic/mitappinventortest/specific-programming-issue/upMDe...
Apr 02 11:58:48 <Jude999> My latest question is on there. thx.
Apr 02 11:59:19 <CedricBeust> Invalid link
Apr 02 11:59:25 <CedricBeust> besides, I know nothing about App Inventor
Apr 02 12:00:01 <Jude999> Try this https://groups.google.com/forum/#!category-topic/mitappinventortest/specific-programming-issue/upMDewqjpQA
Apr 02 12:00:54 <Jude999> My latest question is at the bottom, it takes awhile for help on the forum and they do not have a irc chat :( CedricBeust
Apr 02 12:03:47 <Jude999> Well, this is a android dev channel so you might know a bit! CedricBeust
Apr 02 12:04:09 <CedricBeust> Like I said, I know nothing about App Inventor (had never heard of it actually)
Apr 02 12:04:30 <Jude999> Oh.
Apr 02 12:04:57 * Jude999 is said :( lol
Apr 02 12:05:10 * Jude999 is SAD :(
Apr 02 12:05:31 <Jude999> oh well, I understand.
Apr 02 12:05:54 <Jude999> any other channels that might help?
Apr 02 12:06:12 <Jude999> CedricBeust
Apr 02 12:12:33 <Jude999> Okay CedricBeust, you don't have recommendations ?
Apr 02 12:13:13 <CedricBeust> No
Apr 02 12:13:54 <ktwo> Why use this environment for children
Apr 02 12:14:33 <Jude999> K. Nobody on the #android chat is even responding.
Apr 02 12:14:38 <Jude999> ktwo: ??
Apr 02 12:15:48 <CedricBeust> Yes was wondering about that, why use this App Inventor thing instead of straight Android development?
Apr 02 12:16:47 <Jude999> App Inventor is easier then straight forward development.
Apr 02 12:17:00 <CedricBeust> Obviously not...
Apr 02 12:17:11 <Jude999> no??
Apr 02 12:17:32 <CedricBeust> Well you seem to be stuck on something extremely basic (that would be trivial in regular Android development)
Apr 02 12:18:03 <Jude999> anyway...
Apr 02 12:21:39 <Jude999> not worry.... thanks. bye.
Apr 02 12:54:34 <ege> Hi, I copied over a android app project and compiled it
Apr 02 12:55:27 <ege> It is called androvdr. It crashed on one of my phones so I tried to fix that.
Apr 02 12:55:53 <ege> While the initial crash is fixed it now crashes on both phones at some specific action.
Apr 02 12:56:03 <ege> code is here: https://github.com/ege1/androvdr
Apr 02 12:56:24 <Ashiren> what does the crash say
Apr 02 12:56:50 <ege> and error message is: android.view.View android.widget.LinearLayout.findViewById(int)' on a null object reference
Apr 02 12:57:58 <ege> the mView = (LinearLayout) mActivity.findViewById(R.id.epgsdata_main); returns null
Apr 02 12:58:14 <ege> which may be the issue.
Apr 02 12:58:40 <ege> But I do not have a clue as I'm not a developer...
Apr 02 13:10:30 <CedricBeust> ege: Find the layout file (XML file) and make sure it contains a view with an id "epgsdata_main".
Apr 02 13:12:14 <ege> CedricBeust: Thanks for your answer. It seams to be a "fragmented" view.
Apr 02 13:12:51 <ege> And the LinearLayout part has android:id="@+id/epgsdata_main"
Apr 02 13:13:40 <CedricBeust> It's a fragment, these are still in layout files.
Apr 02 13:13:55 <ege> It also doesn't complain at compile time, just "in use"
Apr 02 13:14:41 <ege> Yes, you are right. I found it, but it does at least contain that id; that's what you meant, right?
Apr 02 13:22:42 <Bantalon> Hello
Apr 02 13:22:47 <Bantalon> Anyone have any experience with google cloud here?
Apr 02 13:23:21 <Bantalon> is it a good solution for a simple web server to host php script files and so on?
Apr 02 13:29:04 <ege> The strange thing is it must have worked before and I only changed acra debugger because it was still trying to use google docs
Apr 02 13:35:57 <Bernzel> Hi. I want to create something like this: http://imgur.com/tFpRGOI where you can scroll vertically down among the images. I'll be fetching the images from a server with Picasso. Can anyone recommend the best/easiest way of accomplishing this? I've been looking at GridView but it seems complicated and strange.
Apr 02 13:54:01 <Bernzel> anyone?
Apr 02 14:54:20 <spykins> Hello everyone, can i send a BroadCast receiver from a class to a fragment in android. I am fetching Adress and Location, I just want to display it in a textview once i get the Address
Apr 02 14:56:08 <Ashiren> yes, but wouldnt broadcastReceiver a bit overkill
Apr 02 14:56:56 <spykins> I am new into Android development
Apr 02 14:57:47 <spykins> I have a service that’s going to fetch the GPS coordinate and the Address.. I have lost track on the Fragment since i started the service
Apr 02 14:58:15 <spykins> Since i don’t have a reference to it, i don’t think i can use callback for it
Apr 02 14:58:27 <spykins> Is there a better way i can implement it??
Apr 02 14:58:54 <Ashiren> ok you could use load broadcastreceiver to activity and activity would tell the fragment
Apr 02 14:59:19 <spykins> yes
Apr 02 15:01:08 <spykins> From what i have read about that.. I have to extend BroadCastReceiver and overide onReceive method… The problem is, It works if i startAction from Activity
Apr 02 15:02:20 <Ashiren> so?
Apr 02 15:02:21 <spykins> But i can’t figure out how to start the Broadcast from another class and receive it on Activity since Activity is already extending AppCompatActivity
Apr 02 15:03:16 <Ashiren> use anonymous class
Apr 02 15:03:34 <Ashiren> actually you could do that in fragment and use getContent().registerReceiver there
Apr 02 15:04:42 <spykins> ok
Apr 02 15:04:54 <Ashiren> ah getContext()..
Apr 02 15:05:08 <spykins> I have the service in my Manifest file
Apr 02 15:05:12 <spykins> as <service
Apr 02 15:05:13 <spykins>             android:name=".service.FetchAddressIntentService"
Apr 02 15:05:14 <spykins>             android:exported="false"/>
Apr 02 15:05:14 <spykins>         <receiver android:name=".service.AddressReceiver">
Apr 02 15:06:10 <spykins> I have a class AddressReceiver extends BroadcastReceiver
Apr 02 15:06:27 <spykins> and i Have the onReceive() in the class
Apr 02 15:07:04 <spykins> How do i put the onReceive in an Activty?
Apr 02 15:07:40 <Ashiren> umm
Apr 02 15:07:45 <Napalm> you dont
Apr 02 15:07:58 <Ashiren> read on java anonymous class
Apr 02 15:08:39 <Napalm> spykins: https://developer.android.com/reference/android/content/ContextWrapper.html#registerReceiver(android.content.BroadcastReceiver, android.content.IntentFilter)
Apr 02 15:08:56 <Napalm> remember to also unregister
Apr 02 15:08:59 <Napalm> or bad things happen
Apr 02 15:13:00 <spykins> I will remember that
Apr 02 15:13:08 <spykins> Thanks for pointing that out… lol
Apr 02 15:14:24 <spykins> Napalm: THis link is talking about ContexWrapper
Apr 02 15:14:39 <Napalm> same thing
Apr 02 15:14:48 <Napalm> Activity extends a ContextWrapper
Apr 02 15:15:04 <spykins> I get
Apr 02 15:15:33 <spykins> but the problem is that i want to send a broadcast message from a class to a Fragment
Apr 02 15:15:42 <Napalm> and?
Apr 02 15:15:59 <spykins> The fragment already extends Fragment…. so i can’t extend BoradcastReceiver
Apr 02 15:16:03 <Napalm> omg
Apr 02 15:16:05 <Napalm> seriously?
Apr 02 15:16:08 <spykins> Yes
Apr 02 15:16:10 <Ashiren> eeyup
Apr 02 15:16:34 <Napalm> spykins: listen.. register your receiver in your Activity.. and then your Activity can call a function you make on your Fragment when it receives the broadcast
Apr 02 15:17:30 <viran> Canvas is based in a Bitmap object, Texture objects are limited in size (lets say 2048x2048), how do you handle custome views that display content that's bigger than the Texture limitation ?
Apr 02 15:18:28 <Napalm> viran: scale up? or software render (yuck!, especially for large images).. or use multiple textures.
Apr 02 15:18:57 <drose379> If I have a task that is currently running on UI thread, but I notice that it causes a slight blockage in the UI when it runs, does it make sense to make a nested Runnable class, and do the work in there, then call a callback in the activity from the runnable when done
Apr 02 15:19:38 <viran> rendering, I though about not using a custom view at all and just create bitmaps in advance and put them all in a\ recycler view
Apr 02 15:19:47 <Ashiren> drose379: thats essentially AsyncTask?
Apr 02 15:19:59 <drose379> Hm pretty much Ashiren
Apr 02 15:20:42 <Ashiren> if it can be asynchrounous then go for it
Apr 02 15:20:45 <drose379> Ashiren: I chose to use Runnable instead of AsyncTask because it doesnt return anything
Apr 02 15:21:09 <Napalm> viran: using a RecyclerView with your own layout is pretty much a custom view.. either way.. its moer work to display a simple image.. its your choice.
Apr 02 15:21:23 <drose379> It takes a Location object and parses it down into a postal code, then calls a method in the activity which uses the code
Apr 02 15:21:33 <drose379> I guess processing Location to postalCode takes a sec
Apr 02 15:21:33 <Ashiren> then use some executor and put Runnables there
Apr 02 15:21:36 <Napalm> viran: is this a photo viewing app? what is the point to this image display? if its not epic'ly needed then i wouldnt bother
Apr 02 15:21:55 <drose379> What do you mean executer Ashiren
Apr 02 15:21:55 <Napalm> viran: just max out your image to the max-tex size and then let ImageView scale up
Apr 02 15:23:07 <Ashiren> drose379: read on ExecutorService ie. ExecutorService.newCachedThreadPool()
Apr 02 15:23:16 <Ashiren> you put Runnables there and they run in background
Apr 02 15:23:55 <viran> Napalm: it's basicly a TextView that displays math equations (with all the math symbols), so I just draw what I need on a bitmap and then draw it on the view's canvas. The issus is the content can easily become very long, going over the bitmap limit in width
Apr 02 15:23:56 <drose379> Ok, any reason it would be better then having a Runnable nested class in the Activity (if this is the only activity that will need to have the task done)
Apr 02 15:23:58 <Napalm> drose379: hold up.. you call a method in the the result back to the Activity
Apr 02 15:24:03 <Napalm> ugh
Apr 02 15:24:11 <drose379> Yes why
Apr 02 15:24:14 <Napalm> drose379: hold up.. you call a method in the Activity after?
Apr 02 15:24:26 <Napalm> and that does what with the postalCode?
Apr 02 15:24:34 <Napalm> this sounds like your using the Geocoder
Apr 02 15:24:38 <drose379> I am Napalm
Apr 02 15:24:48 <drose379> Whats wrong w geocoder
Apr 02 15:24:54 <Napalm> its not on every device
Apr 02 15:25:10 <drose379> Doesnt it come with the sdk
Apr 02 15:25:16 <Napalm> you'll get the Service unavaliable error
Apr 02 15:25:23 <drose379> I get that on emulators
Apr 02 15:25:38 <drose379> Thats really it though, but I've only tried on a few devices I geuss
Apr 02 15:25:41 <Napalm> i have seen several devices report with that issue
Apr 02 15:25:49 <drose379> Any other way to go from Location -> Postal code?
Apr 02 15:25:55 <Napalm> places api
Apr 02 15:26:07 <Napalm> if your already using Google Play Services then its a simple addition
Apr 02 15:26:07 <drose379> Blegh dont wanna connect to an API just for this
Apr 02 15:26:18 <Napalm> drose379: thats what geocoder does
Apr 02 15:26:19 <Napalm> lol
Apr 02 15:26:21 <drose379> Lol
Apr 02 15:26:31 <drose379> I didnt know that, Ok, ill look into it
Apr 02 15:26:34 <Napalm> your device doesnt store all the postal codes for the entire world
Apr 02 15:26:36 <drose379> Thanks for the heads up though
Apr 02 15:26:38 <drose379> Rigfht
Apr 02 15:26:45 <Napalm> not to mention all possible addresses
Apr 02 15:26:57 <Napalm> thats why you defo do not want to do it on the UI thread
Apr 02 15:27:01 <drose379> But wait, what were you saying about calling a callback method in the activity from the runnable?
Apr 02 15:27:12 <Napalm> yes
Apr 02 15:27:22 <Napalm> if your doing that.. then whats the point of your runnable?
Apr 02 15:27:29 <Napalm> use an AsyncTask..
Apr 02 15:27:32 <mohsen_> Can I progammatically put a shortcut for an http website on the homescreen?
Apr 02 15:27:35 <Napalm> or.. do what i do for geocoding
Apr 02 15:27:40 <Napalm> use an intentservice and receiver
Apr 02 15:27:49 <Napalm> its what the SDK suggests and works great
Apr 02 15:27:50 <drose379> All the same idea Napalm
Apr 02 15:28:27 <Napalm> well no.. if you post a runnable off the ui thread.. your callback to the Activity is off the ui thread
Apr 02 15:28:28 <drose379> Oh, I guess I dont have to pass an instance of the activity into this runnable
Apr 02 15:28:40 <Napalm> drose379: it does
Apr 02 15:28:42 <Napalm> its implicit
Apr 02 15:28:47 <drose379> Its not a static class
Apr 02 15:28:54 <drose379> So I still have access to the activities methods
Apr 02 15:29:12 <Napalm> drose379: all anonymous classes contain a reference to their parent class
Apr 02 15:29:16 <drose379> Yes
Apr 02 15:29:21 <drose379> Well, this is not anonymous
Apr 02 15:29:25 <drose379> Its nested
Apr 02 15:29:31 <Napalm> ?
Apr 02 15:29:36 <Napalm> yes,
Apr 02 15:29:38 <Napalm> same deal
Apr 02 15:29:41 <drose379> Right
Apr 02 15:29:46 <drose379> Anyway, ok question
Apr 02 15:29:50 <Napalm> but, thats my point.. now you have a leak
Apr 02 15:29:55 <drose379> How?
Apr 02 15:30:16 <Napalm> your inner class references an Activity that poentially doesnt exist anymore
Apr 02 15:30:31 <drose379> So I _could_ have a leak
Apr 02 15:30:52 <Napalm> yes... so two big scenarios that happen here
Apr 02 15:31:50 <drose379> What are they?
Apr 02 15:32:01 <Napalm> 1. you send off your Runnable to do some work and bad network-connection/slow-server means it takes say 30 seconds (more common than you think).. now the user switches away from your Activity.. like manually or get get a phone call
Apr 02 15:32:31 <Napalm> 2. your operation completes and now calls back to an Activity that has been finished. the object remains with references to all the resources (hence the leak)
Apr 02 15:32:39 <Napalm> well these are steps
Apr 02 15:33:07 <Napalm> 3. now a. you crash because you try accessing things that dont exist
Apr 02 15:33:32 <mohsen_> Can't I?
Apr 02 15:33:42 <drose379> But wouldnt the nested Runnable class finish with the activity?
Apr 02 15:33:45 <drose379> Or no?
Apr 02 15:33:47 <Napalm> no
Apr 02 15:33:55 <drose379> Ok, so EventBus would be great here
Apr 02 15:33:56 <Napalm> its not related to the external running
Apr 02 15:33:59 <Napalm> no
Apr 02 15:34:09 <drose379> Why
Apr 02 15:34:16 <Napalm> EventBus is stupid
Apr 02 15:34:18 <Napalm> lol
Apr 02 15:34:24 <drose379> Same as local broadcast manager
Apr 02 15:34:36 <Napalm> yes and no
Apr 02 15:34:39 <Napalm> it would work
Apr 02 15:34:53 <drose379> But...?
Apr 02 15:35:10 <Napalm> but for operations that have essentially two-way communication are now not events
Apr 02 15:35:22 <drose379> What do you mean?
Apr 02 15:35:51 <Napalm> well its no longer .. this event occured.. but now heres your result
Apr 02 15:36:04 <drose379> And you mean that is incorrect use of EventBus?
Apr 02 15:36:05 <Napalm> ij
Apr 02 15:36:09 <Napalm> yes
Apr 02 15:36:10 <drose379> ij?
Apr 02 15:36:13 <drose379> Oh
Apr 02 15:36:16 <Napalm> ok, let me give you an example
Apr 02 15:36:22 <drose379> No I get it
Apr 02 15:36:37 <drose379> Would this qualify for LocalBroadcastManager then?
Apr 02 15:36:41 <Napalm> 1. you start Activity A and do a background operation.. and now wait for that to complete.. with no way to cancel it or refer to it.
Apr 02 15:36:49 <drose379> ok
Apr 02 15:37:01 <Napalm> 2. you now start Activity B and it has registered for the same callbacks as A. B receives the result for activity A
Apr 02 15:37:06 <drose379> RIght
Apr 02 15:37:07 <Napalm> now you have to hold state in your events
Apr 02 15:37:11 <Napalm> who sent what
Apr 02 15:37:15 <Napalm> .. its no longer events
Apr 02 15:37:20 <drose379> I see
Apr 02 15:37:26 <drose379> Hmm
Apr 02 15:37:38 <drose379> What about passing a callback to the Runnable through the constructor
Apr 02 15:37:55 <drose379> Make a ZipCallback interface, activity implements, pass it to the Runnable
Apr 02 15:37:58 <Napalm> https://developer.android.com/training/location/display-address.html
Apr 02 15:38:00 <Napalm> did you read this?
Apr 02 15:38:06 <drose379> No I didnt
Apr 02 15:38:12 <Napalm> it tells you how to do it
Apr 02 15:38:22 <drose379> Well this kind of goes for any async task
Apr 02 15:38:32 <drose379> So im trying to figure out how to do it the right way
Apr 02 15:38:44 <Napalm> drose379: here's the examples src https://github.com/googlesamples/android-play-location/tree/master/LocationAddress/app/src/main/java/com/google/android/gms/location/sample/locationaddress
Apr 02 15:38:54 <Napalm> this is how to do it
Apr 02 15:38:56 <drose379> Napalm: what if I passed a callback to the Runnable?
Apr 02 15:39:04 <Napalm> ok
Apr 02 15:39:05 <drose379> And the activity closed
Apr 02 15:39:11 <Napalm> then same deal
Apr 02 15:39:13 <drose379> The callback would be null
Apr 02 15:39:16 <Napalm> the callback is the activity
Apr 02 15:39:26 <Napalm> you would have to have a way to keep a reference to your background task
Apr 02 15:39:31 <Napalm> and then null out the callback
Apr 02 15:39:33 <g00s> lol, somebody trying to beat the lolcycle :)
Apr 02 15:39:38 <Napalm> yea
Apr 02 15:39:44 <drose379> lolcycle?
Apr 02 15:39:47 <Napalm> lol
Apr 02 15:39:52 <g00s> only way to win, is to not play the game :D
Apr 02 15:40:28 <drose379> Napalm: ok so in the runnable, before using the callback I passed in, just check if its null first
Apr 02 15:40:35 <g00s> drose379 yes a malicious AI that stymies all efforts for simple code
Apr 02 15:41:02 <drose379> I think thatd work, checking if callback is null
Apr 02 15:41:19 <Napalm> drose379: and provide a method to reset the runnable
Apr 02 15:41:21 <Napalm> reset the callback
Apr 02 15:41:22 <Napalm> *
Apr 02 15:41:37 <drose379> What do you mean, like in onResume I would need to give a new callback?
Apr 02 15:41:57 <drose379> Since its technically a new instance of the activity?
Apr 02 15:42:40 <Napalm> drose379: https://github.com/slightfoot/android-asynctask-correctly/blob/master/AsyncTaskCorrectly/src/com/demondevelopers/asynctaskcorrectly/MainActivity.java
Apr 02 15:42:46 <Napalm> i did that for someone else in the channel .. ages ago
Apr 02 15:42:53 <Napalm> 2013
Apr 02 15:42:56 <drose379> Thank you I will read
Apr 02 15:42:57 <Napalm> fuck me
Apr 02 15:43:02 <Napalm> im old
Apr 02 15:43:02 <drose379> But was what I said correct?
Apr 02 15:43:29 <Napalm> read the codes
Apr 02 15:43:32 <drose379> Ok ok
Apr 02 15:43:34 <drose379> Thanks again
Apr 02 15:43:36 <drose379> Been great
Apr 02 15:43:38 <Napalm> it applies the same to a Runnable
Apr 02 15:43:44 <drose379> Coool
Apr 02 15:43:46 <drose379> Thanks
Apr 02 15:43:51 <Napalm> ps. its old
Apr 02 15:43:57 <Napalm> getLastNonConfigurationInstance is no longer supported
Apr 02 15:43:59 <jug6ernaut> Napalm those brackets tho :|
Apr 02 15:44:31 <Napalm> jug6ernaut: functions always start with brackets on next line... easier to see a function vs. logic
Apr 02 15:44:38 <Napalm> got that from C/C++ but meh
Apr 02 15:44:50 <drose379> They make us do that at school
Apr 02 15:45:24 <g00s> drose379 better than GNU style https://en.wikipedia.org/wiki/Indent_style#GNU_style
Apr 02 15:45:35 <Napalm> drose379: if your using AppCompat.. then use getLastCustomNonConfigurationInstance and onRetainCustomNonConfigurationInstance instead
Apr 02 15:45:46 <drose379> Ok, thanks
Apr 02 15:45:59 <drose379> BTW do you guys ever use Binary search trees?
Apr 02 15:46:01 <Napalm> drose379: its because the support library uses getLastNonConfigurationInstance to hold the fragment manager and loader manager
Apr 02 15:46:08 <Napalm> and your custom object
Apr 02 15:47:10 <jug6ernaut> man idk what Jack was doing, just killed java process using 18GB's fram...
Apr 02 15:47:13 <jug6ernaut> ram*
Apr 02 15:47:41 <Napalm> jug6ernaut: i know your problem
Apr 02 15:47:59 <spykins> Hello @Napalm I want to try LocalBroadcastManager
Apr 02 15:48:02 * jug6ernaut waits for it
Apr 02 15:48:18 <spykins> Napalm: Have you used LocalBroadcastManager before?
Apr 02 15:48:19 <Napalm> jug6ernaut: do you have a gradle.properties in your ~/.gradle? if so does it have org.gradle.jvmargs
Apr 02 15:48:31 <jug6ernaut> hmm
Apr 02 15:48:34 <jug6ernaut> let me check
Apr 02 15:48:35 <Napalm> spykins: read the docs.. it has plenty of examples
Apr 02 15:48:47 <spykins> Ok
Apr 02 15:48:54 <spykins> Thanks
Apr 02 15:49:15 <jug6ernaut> Napalm only has a property enabling the daemon
Apr 02 15:49:32 <Napalm> ah
Apr 02 15:49:40 <Napalm> you can set your jvm args for memory
Apr 02 15:50:05 <Napalm> jug6ernaut: i seem to remember what your talking about mentioned in the Android Dev Summit 2015 videos on the tools
Apr 02 15:50:31 <g00s> i'm kinda nervous about j/j, will keep using the oracle stuff for time being ;)
Apr 02 15:50:41 <Napalm> jug6ernaut: check them out. https://www.youtube.com/playlist?list=PLWz5rJ2EKKc_Tt7q77qwyKRgytF1RzRx8
Apr 02 15:50:47 <jug6ernaut> g00s y
Apr 02 15:50:49 <g00s> at least given all our tools, javac isn't broken :P
Apr 02 15:51:00 <g00s> the only thing that works :D
Apr 02 15:51:49 <g00s> if the quality of j/j ~= gradle plugin, AS we're fucked
Apr 02 15:52:31 <jug6ernaut> i will admin i am kinda suprised that 2.0 went rc
Apr 02 15:53:46 <jug6ernaut> i do welcome j/j how ever. If anything just to eliminate the years of dexing time for libaries
Apr 02 15:54:09 <g00s> jug6ernaut so far the benchmark is 2x slower than oracle
Apr 02 15:54:23 <g00s> i guess they have some tuning to do
Apr 02 15:54:43 <g00s> do you find it to work faster ?
Apr 02 15:55:13 <g00s> i'd have to image by now javac is very mature and optimized
Apr 02 15:55:14 <jug6ernaut> i havent used it extensively, all of my projects of any real size require annotation processors
Apr 02 15:55:18 <jug6ernaut> so no j/j
Apr 02 15:55:21 <g00s> ah
Apr 02 15:56:05 <jug6ernaut> & yeah it is, as such for our current process the javac porton of the process is extremely small
Apr 02 15:56:10 <jug6ernaut> its almost all in the dex
Apr 02 15:58:25 <jug6ernaut> i really wish that jack did lambda inlining though, just dumping in anonymous inner functions makes sense...but still disappointing
Apr 02 15:58:53 <jug6ernaut> Napalm ive seen most of them i think
Apr 02 15:59:09 <g00s> jug6ernaut does it do inlining for N also ?
Apr 02 15:59:27 <g00s> i mean, does it do inlining for N, maybe not for previous for backward compat
Apr 02 15:59:34 <jug6ernaut> for n it compiles to true lambda's, so inlining isnt necessary afaik
Apr 02 16:00:08 <g00s> that sounds like one good reason to use kotlin, if you use lots of lambdas
Apr 02 16:00:40 <jug6ernaut> yeah :\
Apr 02 16:00:46 <Napalm> g00s: https://developer.android.com/preview/j8-jack.html
Apr 02 16:01:17 <Napalm> jug6ernaut: says "The Android N bases its implementation of lambda expressions on anonymous classes. "
Apr 02 16:01:28 <Napalm> so its backwards compat
Apr 02 16:01:34 <drose379> I tried using a callback and Im getting cyclic inheritance..
Apr 02 16:02:02 <Napalm> drose379: you static perhaps?
Apr 02 16:02:05 <Napalm> you need
Apr 02 16:02:18 <drose379> I tried making the nested class static and no didnt change
Apr 02 16:02:20 <jug6ernaut> Napalm i knew it did that for < 23, but it sounds like it does it for 23+?
Apr 02 16:03:00 <Napalm> jug6ernaut: it'll be for 23+ also
Apr 02 16:03:13 <jug6ernaut> :\
Apr 02 16:03:44 <Napalm> jug6ernaut: i mean.. i think "true" lambda's as in whats in Java 8 are done with anon classes anyway.. same byte-code.. all that "we want backwards compat and on all platform" stuff
Apr 02 16:04:27 <drose379> This makes no sense
Apr 02 16:04:35 <drose379> No idea why its cyclic inheritance
Apr 02 16:04:49 <Napalm> drose379: see my PM
Apr 02 16:17:14 <horny-sama> funny that my old android phone supports native phone recording while my nexus 5 don't
Apr 02 16:37:58 <Mavrik> "native phone recording"?
Apr 02 16:43:39 <horny-sama> Mavrik: http://www.droidviews.com/enable-native-call-recording-galaxy-s5-note-3-note-4/
Apr 02 16:48:48 <Bernzel_> Trying to have two imageviews filling the screen width equally in a linearlayout: http://pastebin.com/4wk11unv Not sure how to handle the layout_width of the images to achieve this? The idea is to have 2 images on each row in the scrollView with a small margin in between them.
Apr 02 16:51:29 <orbyt_> Bernzel_: on each imageview use layout_weight = 1
Apr 02 16:51:33 <orbyt_> and set width on each to 0dp
Apr 02 16:58:30 <Bernzel_> perfect, thanks orbyt_
Apr 02 17:05:56 <g00s> we're doomed http://digg.com/video/drone-chainsaw-wtf
Apr 02 17:06:08 <freelancerbob> i am getting null here: Location location = locationManager.getLastKnownLocation(provider);
Apr 02 17:06:29 <freelancerbob> from code here
Apr 02 17:06:30 <freelancerbob> http://www.vogella.com/tutorials/AndroidLocationAPI/article.html
Apr 02 17:11:27 <Mavrik> freelancerbob, and?
Apr 02 17:27:48 <Bernzel_> orbyt_: you experienced with Picasso ? I need to download and attach 12 different images from backend into my scrollview. Is there some compact method for downloading all 12 images at once? Or should I just make 12 different instances of .load etc?
Apr 02 17:33:17 <Napalm> Bernzel_: is there a reason you want to download all the images at once?
Apr 02 17:33:41 <Napalm> Bernzel_: as in, display them all at once? or is this purely a performance thing
Apr 02 17:33:47 <Bernzel_> Napalm: well, the images are appearing in a gallery. So I would like them to be loaded and visible as quickly as possible.
Apr 02 17:34:24 <Napalm> Bernzel_: then just call .load().into(imageView) as each image comes in it will be displayed
Apr 02 17:34:50 <Bernzel_> Copy that Napalm
Apr 02 17:35:11 <orbyt_> Bernzel_: why arent you using a recyclerview
Apr 02 17:35:14 <Napalm> Bernzel_: you probably want to add .centerCrop().fit() so as to not waste memory
Apr 02 17:35:27 <Napalm> orbyt_: he probably is?
Apr 02 17:35:33 <orbyt_> no hes using a scrollview
Apr 02 17:35:44 <Bernzel_> orbyt_: I'm still novice. I don't even know what a RecyclerView is.
Apr 02 17:36:26 <ege> I copied an abandonded project and tried to compile/use it. I managed to migrate the project from eclipse to android studio and compile it. But at one point the app crashes.
Apr 02 17:36:50 <ege> I debugged it down to this
Apr 02 17:37:01 <ege> mView = (LinearLayout) mActivity.findViewById(R.id.epgsdata_main); returns
Apr 02 17:37:22 <ege> After this mView equals null
Apr 02 17:37:57 <ege> And the call of the view leads to a crash later on
Apr 02 17:38:19 <ege> I don't have a clue how to find the route cause of this.
Apr 02 17:39:02 <orbyt_> ege: post your code where .findViewById() is called
Apr 02 17:39:06 <orbyt_> as well as your layout
Apr 02 17:39:44 <ege> Code is here: https://github.com/ege1/androvdr or shall I paste parts of it into channel?
Apr 02 17:39:50 <ege> Files are:
Apr 02 17:39:53 <Napalm> ege: its simple, the view doesnt exist at the time when you called findViewById. which means you have not inflated/added your view
Apr 02 17:40:05 <Napalm> ege
Apr 02 17:40:06 <Napalm> no
Apr 02 17:40:07 <Napalm> dont paste
Apr 02 17:40:14 <Napalm> use hastebin.com or something
Apr 02 17:40:19 <Napalm> www.hastebin.com
Apr 02 17:41:47 <ege> Napalm: Thats what my search also suggested. But for me it looks like it is.
Apr 02 17:42:44 <Napalm> i see your problenm
Apr 02 17:42:58 <Napalm> ege: https://github.com/ege1/androvdr/blob/master/app/src/main/java/de/androvdr/fragments/EpgsdataFragment.java
Apr 02 17:43:18 <Napalm> move everything in onActivityCreated to onViewCreated
Apr 02 17:43:30 <ege> Ah, you are faster than me, was about to paste exactly that link
Apr 02 17:43:52 <Napalm> be sure to call the super onViewCreated
Apr 02 17:44:04 <Napalm> all your fragments should be like that
Apr 02 17:44:21 <Napalm> code that plays with the view should come after onCreateView
Apr 02 17:44:26 <Napalm> see https://github.com/xxv/android-lifecycle
Apr 02 17:44:46 <ege> OK, let me see if I get that.
Apr 02 17:44:53 <Napalm> ege: also, replace your mActivity.findViewById with view.findViewById
Apr 02 17:45:02 <Napalm> view is a parameter to onViewCreated
Apr 02 17:48:24 <ege> OK, what do you mean by "move everything in onActivityCreated to onViewCreated"
Apr 02 17:48:40 <ege> So I rename onActivityCreated to onvViewCreated?
Apr 02 17:49:01 <ege> Napalm: Or where can I find the onViewCreated?
Apr 02 17:49:22 <Napalm> override it
Apr 02 17:49:27 <Napalm> its part of Fragment
Apr 02 17:50:26 <Napalm> ege: if your using Android studio just start typing it.. onViewCre and it should auto complete
Apr 02 17:50:44 <Napalm> ege: https://developer.android.com/reference/android/support/v4/app/Fragment.html#onViewCreated(android.view.View, android.os.Bundle)
Apr 02 17:51:34 <holdsworth> hello guys, I would like to wrap one of my android applications(of which I don't have the source code) with a `tool` that checks that if another application is running then it will continue running, otherwise it will exit; what should I look into?
Apr 02 17:52:04 <ege> Napalm: OK, the shif-shift thing. I'm working the first time with adnroid studio though. Thanks
Apr 02 17:55:23 <Bernzel_> Napalm: something like this perhaps? http://pastebin.com/5vXGRw1K
Apr 02 17:55:56 <Napalm> WTF
Apr 02 17:56:01 <Napalm> you cant be serious?
Apr 02 17:57:15 <Napalm> Bernzel_: have you never heard of arrays?
Apr 02 17:59:55 <Napalm> Bernzel_: hello?
Apr 02 18:06:31 <ege> OK Napalm, I think now I got you. So the "public void onActivityCreated(Bundle savedInstanceState) {"
Apr 02 18:07:11 <ege> stays the same, but the "super.onViewCreated(savedInstanceState);" needs to be changed, while I still have to figure out how...
Apr 02 18:07:18 <ege> Is that right so far?
Apr 02 18:08:22 <Napalm> Bernzel_: this is better, http://pastebin.com/M1ArqMT0
Apr 02 18:09:12 <Napalm> Bernzel_: it would be even better if your UserFileMapping class stored its urls in an array. then all of that creating url arrays is not needed.

Apr 02 18:16:00 <Laynee> Hi good folx.I have one issue.My company is developing an app that has following flow : When user first opens the app, it communicates with SDK (that other company wrote for us, that we can change on request) to verify this use with one piece of information (let's say it's phone number). SDK then communicates with "Server 1" to get the response if user is allowed to proceed.. If the response
Apr 02 18:16:00 <Laynee> is success, app will allow user to use its all features and options and continue communication with "Main server" without any authentication check (because it counts that user is authenticated by SDK communicating with Server 1)..**So the main problem is:** What if "hacker" decompiled this app (reverse engineered it) and altered the  code and made flow  not to communicate with SDK and to
Apr 02 18:16:00 <Laynee> allow user to proceed and use the app and communicate with main server ? I thought of all well known solutions for me (im fullstack dev, not android dev) like secured token that is send on first time when app is communicating with sdk (and then with server1) but all this falls down if hacker can completly avoid communication with skd.. Any thoughts or advices ?
Apr 02 18:16:08 <ege> OK, Napalm, at least the line 69 I managed to do myself ;-)
Apr 02 18:16:10 <Napalm> holy fuck is my thouhts
Apr 02 18:16:15 <Napalm> thoughts
Apr 02 18:16:16 <ege> Thanks!
Apr 02 18:17:18 <Chainfire> Laynee my thought is that you indeed have an issue
Apr 02 18:17:44 <Chainfire> there's essentially no authentication, and as a result, there's no authentication (...)
Apr 02 18:18:10 <Laynee> well the purpose of skd and first server is to authenticate
Apr 02 18:18:16 <Laynee> and hacker can avoid this
Apr 02 18:18:23 <Chainfire> then it doesn't authenticate
Apr 02 18:19:08 <Laynee> so there is no way to prevent hacker to avoid communicating with sdk?
Apr 02 18:19:13 <Napalm> Laynee: you have two options
Apr 02 18:19:53 <Napalm> 1. alter the sdk to use a token. like JWT or oAuth and then send that to the 3rd party server for them to use to authenticate to yours.
Apr 02 18:20:09 <Napalm> 2. proxy all app data traffic through your server
Apr 02 18:20:14 <Napalm> over HTTPS :|
Apr 02 18:20:24 <Napalm> you control the front-door then
Apr 02 18:20:35 <Napalm> hey Chainfire, long time no speak
Apr 02 18:20:57 <Laynee> ok wait one second.. if hacker decompiles app can he avoid all the communication and just procceed forward ?
Apr 02 18:21:09 <Chainfire> Laynee as I understand what you wrote, you are asking "server 1" if this user is OK, then the APP acknowledges this, and "server main" then gives up all it's data
Apr 02 18:21:30 <Laynee> ye
Apr 02 18:21:34 <Chainfire> in other words, server main is completely unprotected, and trusts random socket input
Apr 02 18:21:49 <Chainfire> don't trust input
Apr 02 18:22:08 <jug6ernaut> never trust input lol
Apr 02 18:22:18 <Laynee> Napalm: can you explain "alter the sdk to use a token"
Apr 02 18:22:19 <Napalm> lol
Apr 02 18:22:31 <Laynee> if hacker can avoid communicating with sdk at all, what is use of that
Apr 02 18:22:34 <Chainfire> Napalm aye its been a while
Apr 02 18:22:42 <Chainfire> Laynee we don't know what your app does
Apr 02 18:23:04 <Napalm> Laynee: yes.. the sdk-provider, should give you a token.. and then the "main server" can verify that token over SSL with the sdk-provider;
Apr 02 18:23:06 <Chainfire> but hacker doesn't even need to use your app at all, from what I'm hearing. he could just tap into your server and get whatever he wnats ?
Apr 02 18:23:16 <Napalm> omg. i just ended by sentance with ;
Apr 02 18:23:19 <Napalm> too much code
Apr 02 18:23:32 <Napalm> *sentence
Apr 02 18:24:35 <Napalm> Laynee: got me?
Apr 02 18:24:38 <Laynee> ok i got it all..
Apr 02 18:24:54 <Laynee> its bit confusing because im not developing an app im just arguing with one of the android devs
Apr 02 18:25:00 <Laynee> of how we can solve this :)
Apr 02 18:25:08 <jug6ernaut> Laynee this isnt about developing an app
Apr 02 18:25:13 <Laynee> and im not even responsible for server1 or main server,
Apr 02 18:25:24 <Laynee> i know it is idiotic to provide data without any trust or promise
Apr 02 18:26:02 <Laynee> i know all about anti csrf tokens
Apr 02 18:26:14 <Laynee> ive developed that flows like thousand of times in my career
Apr 02 18:26:28 <Laynee> and i told them to implement something similar
Apr 02 18:26:39 <Chainfire> hmm, attempting to unlink /dev/null reboots a galaxy nexus
Apr 02 18:26:53 <Laynee> Napalm when you said token, you ment on something like anti csrf ?
Apr 02 18:26:59 <Napalm> yes
Apr 02 18:27:09 <jug6ernaut> u still have a galaxy nexus lying around lol
Apr 02 18:27:13 <Napalm> JWT is a known spec
Apr 02 18:27:51 <Laynee> ye i knew.. thats the first thing that came on my mind also... but they are claiming (the android devs) that it cant help
Apr 02 18:28:03 <Laynee> becuase hacker can cut the communication with sdk and continue on
Apr 02 18:28:05 <Napalm> ok Laynee
Apr 02 18:28:10 <Napalm> i can tell you what they are hooked up on
Apr 02 18:28:19 <Napalm> two things
Apr 02 18:29:15 <Napalm> sec
Apr 02 18:29:19 <Napalm> perhaps 1
Apr 02 18:29:20 <Napalm> lol
Apr 02 18:29:52 <adq> if you are unable to protect client side, usually you move part of it on the server side, problem is if you do not have always access to server
Apr 02 18:30:10 <Napalm> anyways, just thinking you could also use the app signing key as part of the authentication.. since if someone decompiled and altered it.. they couldnt recompile it with the same key
Apr 02 18:30:10 <adq> auth, sign, verify, crypt and decrypt everything
Apr 02 18:30:35 <jug6ernaut> adq always assume the client is compromised
Apr 02 18:30:37 <adq> they could hook in memory then Napalm
Apr 02 18:30:37 <Laynee> ok and how to benefit of app signing key ? to send it with each request to "main server"
Apr 02 18:31:04 <Napalm> adq: yea.. true.. i was just discounting it.
Apr 02 18:31:06 <Laynee> imagine this ... you know Viber .. imagine you have viber app that is communicating with its main server.. you dont have authentication in viber, you just confirm that your phone number is the one you provide and you receive sms back and authenticate.. then after that, no auth is needed... imagine that you decompile viber app and cut off sending sms stuff (that represents SDK in my case)
Apr 02 18:31:06 <Laynee> and just proceed on (im not saying you can do this with viber, im just trying to visualize things for you)..
Apr 02 18:32:27 <Napalm> Laynee: and that explain why both the sms-sdk provider and the main-server are both at fault
Apr 02 18:32:30 <Napalm> well
Apr 02 18:32:44 <Napalm> depends on what the sms provider does ..
Apr 02 18:32:47 <Napalm> but anyway
Apr 02 18:33:04 <Napalm> the main-server should have at least some authentication token
Apr 02 18:33:16 <Napalm> even if its just one you get for the api
Apr 02 18:33:20 <Napalm> to identify its clients
Apr 02 18:33:35 <Napalm> otherwise you'll have no way to block specific clients
Apr 02 18:33:49 <Napalm> (most mobile connections get proxied)
Apr 02 18:52:19 <guanche> it's a bit difficult to find out what commands is gradlew actually doing, isn't it?
Apr 02 18:53:06 <jug6ernaut> no, it prints them all out lol
Apr 02 18:53:43 <guanche> I can't see what the command is to produce the apk, though
Apr 02 18:55:16 <guanche> my build spits commands until some target where all the jars are packed together, and then passes through some targets apparently doing nothing, but where the apk should be made
Apr 02 19:03:53 <rudolf_> Hi
Apr 02 19:04:54 <rudolf_> I want to develop an app that reads the meetings from the outlook calendar of a meeting room and display on a mobile device. Is it possible with android or do I need to use a windows device?
Apr 02 19:05:40 <Napalm> rudolf_: where is the outlook calendar of the meeting room stored?
Apr 02 19:05:48 <Napalm> rudolf_: i assume on an exchange server?
Apr 02 19:05:55 <rudolf_> yeah
Apr 02 19:06:19 <rudolf_> And we can all see its calendar
Apr 02 19:06:41 <rudolf_> I mean from the internal network.
Apr 02 19:06:54 <Napalm> rudolf_: https://msdn.microsoft.com/office/office365/APi/calendar-rest-operations
Apr 02 19:06:57 <Napalm> in short.. yes
Apr 02 19:07:42 <rudolf_> So these can be used with android also.
Apr 02 19:07:49 <Napalm> with anything
Apr 02 19:08:09 <rudolf_> All right..I will go through it.
Apr 02 19:08:31 <rudolf_> Napalm: Will it be easier to do this on a windows mobile or will it take the same effort?
Apr 02 19:08:37 <Napalm> same
Apr 02 19:09:01 <Napalm> although i dont see why you need a custom app?
Apr 02 19:09:09 <Napalm> doesnt outlook app show you the calendar?
Apr 02 19:10:45 <Napalm> rudolf_: https://play.google.com/store/apps/details?id=com.microsoft.office.outlook
Apr 02 19:10:49 <rudolf_> Napalm: It does but doing this has some advantages in my office. For example many times it happens that people book a room but don't go in it. Or sometimes we need a room for just 5 minutes.
Apr 02 19:11:08 <rudolf_> In that case, I can add some custom options in the app and make it slightly better
Apr 02 19:11:15 <Napalm> that sounds like the beeb
Apr 02 19:11:16 <Napalm> lol
Apr 02 19:11:38 <rudolf_> Hehe
Apr 02 19:12:39 <rudolf_> Napalm: You won't believe there is a company based on this stuff. They have a device which does all this.
Apr 02 19:13:30 <Napalm> rudolf_: yea i know. beeb got them installed whilst I was working there.. touch screen tablets on posts next to each meeting room door
Apr 02 19:14:12 <rudolf_> Yea...it is evoko room manager.
Apr 02 19:15:20 <rudolf_> They provide nice custom options. It will be cool if I develop something like that. My HR will be happy :P
Apr 02 19:20:54 <cyberspace009> hi!
Apr 02 19:21:50 <Ashiren> happy Caturday
Apr 02 19:23:40 <g00s> Napalm still happy with the android binding library ?
Apr 02 19:23:45 <g00s> was going to give it a try
Apr 02 19:24:30 <Napalm> yes really happy
Apr 02 19:24:44 <Napalm> one of its best features is it updates the views always on the UI thread
Apr 02 19:24:58 <Napalm> saves a lot of hassle
Apr 02 19:25:11 <g00s> does it slow down builds at all ?
Apr 02 19:25:16 <Napalm> nope
Apr 02 19:25:21 <g00s> ok cool
Apr 02 19:25:23 <orbyt_> what lib^
Apr 02 19:25:34 <Napalm> orbyt_: https://developer.android.com/tools/data-binding/guide.html
Apr 02 19:26:15 <cyberspace009> Can anyone help me with an issue on android? I have this system error on W/System.err: Caused by: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.
Apr 02 19:26:15 <cyberspace009> I have the complete list here: http://hastebin.com/icatarumun.avrasm
Apr 02 19:26:18 <orbyt_> oh though you were talking about a third part lib
Apr 02 19:26:22 <orbyt_> thought*
Apr 02 19:26:43 <orbyt_> party* ffs my spelling
Apr 02 19:27:43 <Napalm> cyberspace009: the device does not contain the public CA cert to authenticate against
Apr 02 19:27:51 <g00s> Napalm i saw this the other day http://stfalcon.com/en/blog/post/faster-android-apps-with-databinding
Apr 02 19:27:57 <g00s> but you probably know all of it
Apr 02 19:27:58 <Napalm> cyberspace009: save the CA cert for the url and pin it in the app
Apr 02 19:28:56 <cyberspace009> Napalm: ok, I'll look into that. I have the cert saved in res/raw folder but I guess that is not how it is done?
Apr 02 19:29:55 <Napalm> cyberspace009: https://square.github.io/okhttp/2.x/okhttp/com/squareup/okhttp/CertificatePinner.html
Apr 02 19:30:54 <Napalm> cyberspace009: actually perhaps it wasnt cert pinning i was thinking of.... anyhow.. read this https://github.com/square/okhttp/wiki/HTTPS
Apr 02 19:31:12 <Napalm> https://github.com/square/okhttp/blob/master/samples/guide/src/main/java/okhttp3/recipes/CustomTrust.java
Apr 02 19:31:13 <Napalm> thats the one
Apr 02 19:32:03 <Napalm> g00s: looks like the article covers the big points
Apr 02 19:34:07 <divStar> hello guys :)... I got a problem - I am assigning a custom ArrayAdapter to a ListView. Inside getView I am creating an inflatedView by using LayoutInflater.from(context).inflate(R.id.listitem_row, parent, false). Everything shows up as expected. But how do I add onItemClick to the ListView?
Apr 02 19:35:02 <divStar> I already tried listView.setOnItemClickListener and implemented onItemClick, but the Log.d-message inside that one never shows up
Apr 02 19:35:03 <cyberspace009> Napalm: thanks! I'll look into this
Apr 02 19:36:04 <Napalm> divStar: your listitem_row probably contains a focusable view like EditText
Apr 02 19:36:29 <Napalm> divStar: i suggest you simply use a RecyclerView.. much nicer and simple
Apr 02 19:39:15 <divStar> http://pastebin.com/uL4SUtY4
Apr 02 19:39:22 <divStar> ah - hm.. maybe
Apr 02 19:49:26 <Alina-malina> anyone that is developing android apps with python?
Apr 02 19:49:43 <Napalm> Alina-malina: are you insane?
Apr 02 19:49:49 <Alina-malina> O_O
Apr 02 19:49:54 * Napalm sorry, but someone had to say it
Apr 02 19:49:56 <Alina-malina> Napalm, what?
Apr 02 19:50:17 <Alina-malina> what is wrong with what i said?
Apr 02 19:50:59 <divStar> apparently it's possible, Napalm ( https://ep2013.europython.eu/conference/talks/developing-android-apps-completely-in-python )
Apr 02 19:51:17 <Napalm> divStar: yea, its probably your RatingBar.. try removing it from the layout temporarily.. if the item rows are clickable then.. theres a fix for it
Apr 02 19:51:36 <divStar> no - I went RecyclerView now, Napalm - thanks for the pointer
Apr 02 19:52:00 <Napalm> yw
Apr 02 19:52:02 <divStar> not entirely sure how it'll all play nicely together, but I bet it will somehow :)
Apr 02 19:56:15 <g00s> it may be possible to eek out some contraption in Python
Apr 02 19:57:18 <g00s> but not a good fit
Apr 02 19:59:53 <rudolf_> Any idea why will a company disable quick charge in its device when it is supported by the chipset/processor?
Apr 02 20:00:08 <Napalm> yea, they are dicks
Apr 02 20:00:24 <Napalm> also, probably some battery issues with heat whilst charging
Apr 02 20:00:25 <g00s> rudolf_ just a guess, the engineers may have decided device would overheat
Apr 02 20:00:28 <rudolf_> SD650 supports quick charge 3.0 but still it is disabled by Xiaomi in note 3
Apr 02 20:00:31 <rudolf_> Hm
Apr 02 20:01:01 <g00s> Toshiba just had a huge ass recall of devices with melting batteries :)
Apr 02 20:01:16 <g00s> like 2011-2016 , 100k devices
Apr 02 20:01:20 <Napalm> rudolf_: batterys have C ratings on their possible charge and discharge rates
Apr 02 20:01:20 <rudolf_> Overheating might be the reason. The stupid MIUI heats the mobile even when not on charging.
Apr 02 20:02:06 <Napalm> rudolf_: i bet their "cheaper" battery doesnt support the charging rate, if you charge too quickly the battery can "explode"... catch fire
Apr 02 20:02:14 <rudolf_> That's interesting lol
Apr 02 20:02:37 <rudolf_> Napalm: The developers are ready to build custom kernels to enable quick charging 3.0 :D
Apr 02 20:02:49 <Napalm> "the developrs"?
Apr 02 20:02:54 <g00s> lol, terrorists ?
Apr 02 20:03:16 <rudolf_> Lol
Apr 02 20:03:47 <g00s> and . that would be a great reason for voiding warranty if not left as stock ;)
Apr 02 20:03:59 <rudolf_> And I recently saw a kernel allowing upto 3000mA of current during charginf
Apr 02 20:04:02 <rudolf_> charging*
Apr 02 20:04:21 <rudolf_> g00s: The good thing is that Xiaomi does not void warranty on root.
Apr 02 20:04:44 <rudolf_> So people can come back to stock to claim warranty.
Apr 02 20:04:57 <Napalm> rudolf_: i cant wait for this to happen in peoples pockets https://youtu.be/ixIOEPnsgbI?t=26s
Apr 02 20:05:15 <Napalm> :|
Apr 02 20:05:17 <rudolf_> That sound lol
Apr 02 20:05:39 <g00s> but seriously, its bad news when a lithium fire happens aboard aircraft, probably everybody in the cabin is exposed to HF
Apr 02 20:05:51 <rudolf_> Napalm that was a Napalm :P
Apr 02 20:05:58 <g00s> since the air is recirculated
Apr 02 20:06:29 <rudolf_> g00s: But lithium batteries were not used in aeroplanes until recently, right?
Apr 02 20:07:25 <g00s> not sure who is using what now, i think boeing had some problems and elon had to give them a hand
Apr 02 20:07:32 <g00s> but, just from a passenger's phone or laptop
Apr 02 20:07:55 <rudolf_> Airbus is planning to use it...still pending certification I think
Apr 02 20:07:58 <g00s> i would't be surprised if sometime down the road everybody got cancer or something in such event
Apr 02 20:12:32 <rudolf_> New way of starting fire in an aircraft will be installing a custom kernel with no charging current check and charging the phone using a power bank lol
Apr 02 20:13:39 <LinnLonnn> Hi. I have a rooted Galaxy S4. I keep getting spam calls from one particular number. Is there a way I can have it be automatically answered and play some super obnoxious recording on loop to the caller? Are there any API or technical troubles with this? I know recording calls is a pain by itself.
Apr 02 20:14:02 <rudolf_> lol...tasker does not have anything for this?
Apr 02 20:14:36 <rudolf_> Btw why not simply block it?
Apr 02 20:14:42 <LinnLonnn> Not sure. Never used Tasker. I want to play a super annoying recording for them on repeat.
Apr 02 20:14:55 <LinnLonnn> Because this is more fun.
Apr 02 20:15:56 <rudolf_> Try tasker...I am not sure but it might have something...some call receive event.
Apr 02 20:18:57 <LinnLonnn> rudolf_, I'm guessing there isn't an action to play an audio file into a call on Tasker. Let me try to find some docs.
Apr 02 20:19:52 <rudolf_> I think we can play a media file in background when a particular caller calls.
Apr 02 20:20:19 <rudolf_> And I just saw that selective auto answer is there.
Apr 02 20:22:49 <LinnLonnn> rudolf_, I'd prefer to not have it play anything out of the speaker. I only want them to hear it when they call me.
Apr 02 20:24:50 <gopar>  How do I read a file from the assets directory in a junit?
Apr 02 20:25:15 <gopar> I'm new to android and java in general so not quite sure how to do it. Stackoverflow results weren't helping either :/
Apr 02 20:25:52 <rudolf_> LinnLonnn: Ah...that would be difficult. I don't know if it is possible at all.
Apr 02 20:26:30 <LinnLonnn> rudolf_, hmm. I'm happy with S4-only hacks.
Apr 02 20:29:17 <horny-sama> I might get a window phone just for its ability to record phone call natively
Apr 02 20:45:45 <divStar> hm weird.. I adjusted the ListView I had to a RecyclerView, but it still does not accept any clicks/touches... I don't really want to remove that rating bar :/
Apr 02 20:46:27 <divStar> oh wait.. no setOnItemClickListener added lol... sorry .. false alarm I guess
Apr 02 20:46:43 <StephenS> is it normal that for header text in navigation drawer, I get different text on preview in android studio and diff text on emulator?
Apr 02 20:48:00 <br4ve-trave1er> StephenS, doesn't sound too normal
Apr 02 20:48:07 <StephenS> hmm, how to debug?
Apr 02 20:48:13 <br4ve-trave1er> StephenS, What's the difference in text?
Apr 02 20:48:41 <StephenS> well on emulator, I get NavDrawer, which is the name of my main java class, and on preview in android-studio I get the normal name of my app
Apr 02 20:48:59 <StephenS> bleh
Apr 02 20:49:05 <StephenS> I just saw manifest file, its messed up therw
Apr 02 20:49:10 <StephenS> dunno why though :P
Apr 02 20:49:50 <StephenS> anyway, how can I edit background of navigation drawer, currently its all white :O
Apr 02 20:50:26 <Napalm> android:background="#00CC66"
Apr 02 20:50:32 <br4ve-trave1er> ^
Apr 02 20:50:33 <Napalm> hey now its an aweful green
Apr 02 20:51:46 <br4ve-trave1er> but yeah, in your layout for the nav drawer, set the nav drawer's android:background="whatever_color_youd_like"
Apr 02 20:58:14 <RustyShackleford> how do you handle versioning?
Apr 02 20:58:25 <RustyShackleford> versionName/versionCode/revisionCode
Apr 02 20:58:44 <RustyShackleford> I want to go with a semantic versioning scheme
Apr 02 20:59:24 <r4lph> versionCode/versionName/patch
Apr 02 21:00:18 <br4ve-trave1er> RustyShackleford, follow semantic versioning when you update your app
Apr 02 21:00:39 <br4ve-trave1er> RustyShackleford, in your manifest you can use android:versionCode and android:versionName to specify your version
Apr 02 21:00:52 <br4ve-trave1er> the code should increment, the name should follow semantic versioning
Apr 02 21:00:59 <RustyShackleford> yes I understand that
Apr 02 21:01:04 <RustyShackleford> oh the manifest part
Apr 02 21:01:17 <r4lph> http://pastebin.com/iU90Dezk
Apr 02 21:01:20 <RustyShackleford> how do you pick versionCode? Just increment an integer?
Apr 02 21:01:28 <br4ve-trave1er> that's up to you.
Apr 02 21:01:29 <RustyShackleford> or maybe the date? 20160402
Apr 02 21:02:25 <br4ve-trave1er> date's not terrible, but keep in mind that the versionCode is limited to values below 2147483647
Apr 02 21:02:48 <br4ve-trave1er> so if you just increment each time you update, and rely on the string for what's actually happening, you might be better off
Apr 02 21:03:55 <br4ve-trave1er> although it would take...a lot of version changes to hit that value even if using the date
Apr 02 21:05:35 <br4ve-trave1er> at any rate, if you start out with 1 as your version code, you can keep a "count" of different versions
Apr 02 21:05:47 <br4ve-trave1er> which is mildly useful, or at the very least interesting
Apr 02 21:06:36 <br4ve-trave1er> so like version 1.4.12 could be versionCode=37
Apr 02 21:07:06 <br4ve-trave1er> which helps you keep track in your head how many times you've changed your app enough to call it a new version
Apr 02 21:09:00 <Napalm> RustyShackleford: just increment the versionCode and then custom write your versionName in your gradle to include all the finer details

Apr 02 21:18:41 <maguire>   byte[] data = getBitmapAsByteArray(img); // this is a function ------- can someone explain this line to me, he says it's a function but shouldn't it be like class.functionname
Apr 02 21:21:21 <maguire> i'm working on a project for school where i decided to let the person use select an image from their camera phone directory, but i'm having trouble figuring out how to get the image into a database
Apr 02 21:22:41 <maguire> oh what a sec i see he has that method defined below lol
Apr 02 21:33:54 <RustyShackleford> Napalm: so wait, is there a gradle task that can handle this for me?
Apr 02 21:34:11 <RustyShackleford> increment 0.1.0 to 0.2.0 and it will handle versionCode for me?
Apr 02 21:34:23 <RustyShackleford> also, do you set revisionCode too?
Apr 02 21:56:04 <yonatankoren> Does anybody here know where I can get / buy some good dynamic backgrounds for my app login page?
Apr 02 21:56:30 <yonatankoren> Maybe a pattern, maybe a video background actually
Apr 02 22:11:24 <freelancerbob> it is possible send info from fragment to activity atribute ?
Apr 02 22:12:59 <freelancerbob> i have atribute in acivity, for example public String s; and i want call it from fragment getActivity.s="test"  . It is possible ?
Apr 02 22:13:35 <g00s> freelancerbob no
Apr 02 22:14:01 <g00s> well, lol, you could do ((MyActivity)getActivity()).s="test"
Apr 02 22:14:17 <g00s> but thats pretty crappy, hope you don't do it :D
Apr 02 22:17:11 <freelancerbob> why it's crappy ?
Apr 02 22:18:03 <freelancerbob> what is better workaround ?
Apr 02 22:29:49 <alphamule> "<Laynee> and i should ask this in android-dev..."  Did Laynee ever get an answer?
Apr 02 22:30:43 <alphamule> I'm curious about something.  Some applications seem to prefer specific SU's.
Apr 02 22:31:01 <alphamule> Same with stuff like BusyBox.
Apr 02 22:31:18 <alphamule> I'm wondering what the main differences are between various SU providers.
Apr 02 22:31:47 <alphamule> And do I need to worry about this when writing root apps?
Apr 02 23:01:46 <syndarion> Hello all! I'm trying to figure out what the best way is to fetch some data from a few different endpoints in Android. Say I have three Activities, that each get their data from a different endpoint, should I use three AsyncTasks, or better use three IntentServices, or even a single Service or Thread? Thanks for any help :)
Apr 02 23:03:42 <divStar> does the data from the endpoints depend on each other in whatever way? Or could it be displayed entirely independent from each other?
Apr 02 23:05:09 <syndarion> Independently. Say one is a list of announcements, and another is a list of users. Both would need to be stored in an sqlite database, and then update the appropriate view.
Apr 02 23:05:46 <divStar> well.. it also depends on how many requests you might have going on at the same time
Apr 02 23:06:50 <divStar> I for instance implemented some AsyncTask classes in order to download an image and read it into a Bitmap file , which I then display in a given WeakRefrence<ImageView> in onPostExecute
Apr 02 23:07:18 <syndarion> It needs to do about one request per activity
Apr 02 23:07:27 <syndarion> I feel like this is good for AsyncTask
Apr 02 23:07:51 <divStar> yeah.. from what I have heard and read, one should use AsynTask for such relatively short asynchroneous things
Apr 02 23:08:04 <syndarion> Thanks :)
Apr 02 23:08:16 <jug6ernaut> asyntasks
Apr 02 23:08:17 <syndarion> I've been Googling and searching SO, but opinions seem to be divided
Apr 02 23:08:17 <divStar> but if you had something that takes a longer time going on (e.g. encoding a video), I'd probably go for a real thread or possibly a threadpool
Apr 02 23:08:18 * jug6ernaut shutters 
Apr 02 23:09:15 <divStar> You might want to look into this, syndarion : http://developer.android.com/training/multiple-threads/run-code.html
Apr 02 23:09:27 <divStar> for if you decide to not use AsyncTask
Apr 02 23:10:01 <syndarion> Would you say my situation isn't ok for AsyncTask?
Apr 02 23:10:44 <divStar> I would say it is, but I believe someone else might say it isn't, because AsyncTasks are a bit ugly in some regards and perhaps not as straight-forward as a Runnable
Apr 02 23:11:06 <syndarion> I'll go with the AsyncTask for now, but I'll keep Runnable in mind
Apr 02 23:11:15 <jug6ernaut> if all u need to do is it 1 end point per activity
Apr 02 23:11:20 <jug6ernaut> asynctask should be fine
Apr 02 23:11:41 <divStar> cheers! *afks*
Apr 02 23:11:44 <jug6ernaut> but if u have to hit more, or do anything more complicated there are better but heavier options
Apr 02 23:12:54 <pgs> AsyncTask.onPostExecute(result) runs on the UI thread, which means it keeps a reference to the activity
Apr 02 23:12:54 <syndarion> For now it's one endpoint per activity. What are the heavier options, in case I need to hit more in the future?
Apr 02 23:13:13 <pgs> so if the device is rotated during your fetch, the activity is leaked
Apr 02 23:13:38 <syndarion> pgs, So you say don't use AsyncTask?
Apr 02 23:13:45 <pgs> ans you may be trying to display your result on an activity that is no longer displayed
Apr 02 23:14:02 <syndarion> It would store the data in an sqlite db
Apr 02 23:14:27 <pgs> yeah, just use a thread
Apr 02 23:14:36 <syndarion> A regular Thread?
Apr 02 23:15:01 <pgs> thread, runnable, intent service, ...
Apr 02 23:15:18 <jug6ernaut> does the UI need to be updated?
Apr 02 23:16:13 <syndarion> Yes it does need updating. When the Activity starts, it should check with an endpoint to see if there's new data, and pull it in if there is, saving it to the DB. Then update the UI.
Apr 02 23:17:09 <paresh> pgs, got anything where I can read about context leaks
Apr 02 23:17:24 <paresh> and other common pitfalls
Apr 02 23:17:31 <jug6ernaut> leakcanary
Apr 02 23:17:54 <paresh> thanks jug6ernaut
Apr 02 23:18:03 <pgs> leakcanary is good
Apr 02 23:18:47 <syndarion> And another question is, say I use an IntentService, should I create one per endpoint, or are there better ways?
Apr 02 23:20:45 <jug6ernaut> let me ask u this, if ur call is in progress and ur activity closes
Apr 02 23:20:52 <jug6ernaut> what would u want to happen
Apr 02 23:21:09 <syndarion> I'd still like the DB to be updated
Apr 02 23:22:30 <jug6ernaut> IntentService with localbroadcast or EventBus would probably work well
Apr 02 23:23:11 <syndarion> Thanks! :)
Apr 02 23:23:43 <syndarion> And would it be okay to create one FetchService, and based on the parameter it gets, it does the right request?
Apr 02 23:23:57 <jug6ernaut> as someone above pointed out tho, just make sure you account for when your activity is closed. Dont try and update it after ondestroy/onpause etc have been called
Apr 02 23:24:04 <syndarion> It'd be quite a long method
Apr 02 23:24:19 <jug6ernaut> i would probably make them separate
Apr 02 23:24:26 <syndarion> Thought so
Apr 02 23:25:15 <StephenS> hey, I have a valid JSON, I just validated it, however on JSONObject in java I get an exception, how come? Here is json: [{	"success": true,	"msg": "Showing all info" )]
Apr 02 23:25:47 <paresh> StephenS, try JSONArray
Apr 02 23:25:47 <jug6ernaut> pastebin
Apr 02 23:25:53 <StephenS> paresh, thanks :)
Apr 02 23:26:54 <paresh> StephenS, http://developer.android.com/reference/org/json/JSONArray.html#getJSONObject(int)
Apr 02 23:26:55 <paresh> :)
Apr 02 23:27:48 <StephenS> at 0 of type org.json.JSONObject cannot be converted to boolean
Apr 02 23:28:04 <StephenS> Value {"success":true,...
Apr 02 23:28:06 <StephenS> ? :O
Apr 02 23:29:30 <StephenS> hmm sec
Apr 02 23:30:20 <StephenS> ok works now super cool :)
Apr 02 23:31:59 <syndarion> Should I use Volley for http requests? Or just plain HttpURLConnection?
Apr 02 23:32:56 <jug6ernaut> retrofit
Apr 02 23:33:02 <paresh> yea
Apr 02 23:33:53 <syndarion> paresh, yea to retrofit?
Apr 02 23:33:59 <paresh> syndarion, yes
Apr 02 23:34:04 <paresh> retrofit2.0 ;)
Apr 02 23:34:04 <syndarion> Thanks
Apr 02 23:34:32 <paresh> I was using OkHTTP before using retrofit
Apr 02 23:34:44 <paresh> retrofit reduced plenty of lines for me
Apr 02 23:35:30 <paresh> syndarion, samples on retrofit github are really helpful
Apr 02 23:35:31 <paresh> ;)
Apr 02 23:35:32 <paresh> https://github.com/square/retrofit/tree/master/samples
Apr 02 23:42:59 <syndarion> So I can use Retrofit to fetch data from an endpoint, and store it in the DB? Do I still need an IntentService?
Apr 02 23:43:33 <pgs> yes, your service will call retrofit
Apr 02 23:44:41 <RustyShackleford> how do you set versionCode and versionName?
Apr 02 23:44:51 <RustyShackleford> do you bother with revisionCode?
Apr 02 23:48:47 <orbyt_> syndarion & pgs ...what? You dont need an IntentService to make simple http requests lol.
Apr 02 23:49:39 <pgs> well, you'll get an exception for doing network access on the main UI thread
Apr 02 23:50:10 <orbyt_> Yes, but IntentServices are not how you make simple network requests off the main thread.
Apr 02 23:50:35 <pgs> one of many ways
Apr 02 23:50:36 <orbyt_> Retrofit comes with it own way to make async calls. Better yet, make Retrofit return an Observable and subscribe on an io thread
Apr 02 23:50:45 <pgs> yep
Apr 02 23:51:23 <syndarion> orbyt_, and what if I was a beginner, who just needed to fetch some data and store it in a sqlite DB? :P
Apr 02 23:51:35 <orbyt_> what about it
Apr 02 23:52:04 <syndarion> I'd say it sounds rather complicated, no?
Apr 02 23:52:11 <orbyt_> what does
Apr 02 23:52:34 <syndarion> The Observable and IO thread
Apr 02 23:52:41 <syndarion> Do you have an example of that, perhaps?
Apr 02 23:52:45 <orbyt_> its 2 lines of code
Apr 02 23:52:47 <orbyt_> lol
Apr 02 23:52:55 <orbyt_> what exactly are you trying to do
Apr 02 23:54:21 <syndarion> When the Activity starts, fetch some data, that's it :p I was leaning towards an AsyncTask, and a HttpRequest (or whatever it's called in Java), but I was advised to use Retrofit
Apr 02 23:54:41 <orbyt_> everything you need: https://github.com/codepath/android_guides/wiki/Consuming-APIs-with-Retrofit
Apr 02 23:55:15 <syndarion> Thanks :)
Apr 03 00:03:13 <StephenS> hmm, so when I do AsyncTask in a different class, I call method doSync() in a different class, but from some reason I get access to nullpointer? :O
Apr 03 00:18:32 <sector_0> what's the best websocket library for android?
Apr 03 00:18:50 <sector_0> and by best I mean, most mature, stable, and compliant
Apr 03 00:20:13 <divStar> holy cow.. android STILL cannot properly display dashed lines without having to turn off hardware acceleration on the view at least? .. lol.. disappointing
Apr 03 00:26:55 <recursor94> So I read somewhere that it's technically incorrect to modularize android app code into many different classes as you would in a standard java app.  Is that true?  Will the performance loss be drastic if I do anyway?
Apr 03 00:35:41 <Maurits-> recursor94: technically incorrect is way too strong
Apr 03 00:36:13 <Maurits-> recursor94: it's unlikely to matter, there are a few limits in terms of total number of methods
Apr 03 00:36:23 <Maurits-> recursor94: but performance-wise you should be fine
Apr 03 00:37:50 <Maurits-> it's not something you should worry about in advance in any case
Apr 03 00:50:06 <recursor94> Okay thanks, I really appreciate that feedback.
Apr 03 01:19:52 <g00s> having trouble finding docs on the xml layout <fragment> element
Apr 03 01:20:12 <g00s> has to be there somewhere. are there limitations to what can be assigned to <fragment> ?
Apr 03 01:37:28 <RustyShackleford> there must be a way to get gradle to automatcially generate a versionCode that is yyyymmdd
Apr 03 01:37:46 <RustyShackleford> i could add time to that if I want
Apr 03 01:55:55 <pfn> easy peasy
Apr 03 02:02:13 <pfn> I would say that's generally not recommended
Apr 03 02:29:55 <CedricBeust> This kind of thing totally invalidates incremental compilation
Apr 03 02:34:30 <pfn> not just that but repeatable. builds
Apr 03 02:40:52 <recursor94> Is there a way I can create an appcompat activity in android studio from the menu instead of directly defining my own class from scratch?
Apr 03 02:45:28 <recursor94> Oh, it seems that I don't have the support library installed.
Apr 03 02:45:58 <orbyt_> pretty sure the default wizard template is an appcompat activity anyway
Apr 03 02:46:42 <recursor94> No it tells me I have to be using at least sdk version 15 to create a new activity
Apr 03 02:47:19 <recursor94> Or maybe 8, I forget the exact number.
Apr 03 02:49:50 <jug6ernaut> return o -> o.map(d -> gson.fromJson(gson.toJson(d.getValue()),type));
Apr 03 02:49:56 * jug6ernaut feels bad
Apr 03 02:51:40 <recursor94> No, you're right it does use the support library activity by default.  But then why can I only create one with a minimum sdk of at least 7?  I thought the point of the support library was to be backwards compatible with all older android OS versions.
