**** BEGIN LOGGING AT Sun Sep 14 02:59:59 2014 Sep 14 03:00:10 g00s any suggestions? at work we have set up with maven, but we gen a aar file so it's kind of a pain to reimport it each time Sep 14 03:00:38 MartialLaw lol…. I really dont mean to offend but there you go again with the "doesn't seem to work properly" user comments Sep 14 03:01:07 MartialLaw http://i.imgur.com/jacoj.jpg Sep 14 03:01:55 "doesn't seem to work properly" isn't a valid issue description? Sep 14 03:02:00 lasserix hmm, i guess i do it a bit differently; i publish the aar to my local m2repository; and then the project that uses it just has mavenLocal() as a repository, and a dep on the project Sep 14 03:02:13 but i dont use maven Sep 14 03:02:19 so if you change your library it updates automatically? Sep 14 03:02:36 the only way for that to happen, is if the library is a sub-module of the project Sep 14 03:02:38 how do publish to your local m2 repo without maven? do you know a tutorial on how to set that up? Sep 14 03:02:52 yeah Sep 14 03:03:05 m2repository is just a file structure Sep 14 03:03:15 xml, poms, shas, aars, etc Sep 14 03:03:20 the gradle stuff handles this Sep 14 03:03:33 StingRay_: you're right. you're right. no offense taken dude Sep 14 03:19:53 Is there any way to have a layout automatically do this? http://i.imgur.com/jJdb5z9.png (with 2 imageviews, automatically overflowing/aligning). I've been trying a bunch of different settings and I can't get it to work Sep 14 03:20:36 thats like a flowlayout Sep 14 03:20:36 eh? Sep 14 03:21:03 oh, yeah Sep 14 03:21:04 googling it brings this up - but its probably ancient lib https://github.com/ApmeM/android-flowlayout Sep 14 03:21:50 Yeah, looks pretty old... odd, I would have thought that it would be something stock Sep 14 03:22:05 i wouldnt think its very common Sep 14 03:22:17 why would you want to waste that much space? Sep 14 03:23:37 oh, hm, yeah I guess it is kind of a waste of space Sep 14 03:23:47 only if they're too big, though! otherwise it's fine Sep 14 03:24:01 so a random waste of space Sep 14 03:24:07 thats totally not predictable Sep 14 03:24:11 aegamesi: there is something called flow layout which was a demo project by Romain Guy that he uses to demo how to do custom views/viewgroups Sep 14 03:24:47 StingRay_: it's a sort of calculator, with a history of what you've calculated. On the left is the input, and on the right is your result Sep 14 03:25:00 lasserix: oh, I see that! Hey, that looks pretty interesting anyway. Sep 14 03:25:31 aegamesi: that would be pretty easy just be using either a relative layout with layout_below and layout align Sep 14 03:25:39 then toggle visibility if you need which view Sep 14 03:25:57 or do the same with a linear layout (vertical) in the second row set gravity right Sep 14 03:26:14 well, yeah for the linear layout but if they can both fit on the same line, it'd be nicer to do that. Saving space and all Sep 14 03:26:35 you mean you want them to me colinear if they fit and stacked if they dont? Sep 14 03:26:58 Yeah Sep 14 03:27:21 Ah. Great. Finally stumbled upon an article which specified that the Google Wear source code is only *partial*, and therefore not buildable at present. Sep 14 03:27:28 Well that was a wasted couple of days. Sep 14 03:31:34 TheMadcapper oh yeah, i remember ron_frown stumbling into that Sep 14 03:31:43 but i thought it was the whole thing Sep 14 03:32:18 are there any solid figures on wearables cause to me is a waste Sep 14 03:32:27 well, thats the nature of google's documentation - wasted days ... Sep 14 03:32:37 could turn into wasted years if you are at it long enough ;) Sep 14 03:33:05 http://www.youtube.com/watch?v=bR8D4Uybtzs hehe Sep 14 03:33:22 I guess I have to return this watch and tablet, then. No use for them if I can't do what I want with them, and I doubt the source will be out within the 14 day return policy. :\ Sep 14 03:33:42 poor themadcapper .... bounced around and found no love for all the work :( Sep 14 03:34:14 At least I got a little insight into the Android development process Sep 14 03:34:33 its more like development chaos Sep 14 03:34:51 Oh good. It isn't just me, then. :) Sep 14 03:34:51 mixed in with gung-bro Sep 14 03:34:57 <3 TheMadcapper i love ur effort Sep 14 03:35:01 heh - and this channel will make you work for it ;) Sep 14 03:48:17 hello all Sep 14 03:59:01 huh so i imported as a new module into my AS project and now my intellij project (the library) got stripped only ad .idea and gen (looks like everything but wha tis in the gitignore) Sep 14 03:59:46 can i export a module in android studio as a library project? Sep 14 04:00:35 lasserix you are wanting to have an external lib project setup with gradle ? Sep 14 04:10:54 StingRay ideally id like to be able to work on my library project in intellij, and have it in my game app in android studio, where any changes i make in intellij will be automatically reflected in the game app Sep 14 04:11:48 but if i can just export the module as a new library project i can just do everything in AS i guess Sep 14 04:36:16 lasserix, if you're already using intellij there isn't a whole lot of reason to use android studio Sep 14 04:36:43 there's actually next to no reason... Sep 14 04:36:53 other than better gradle integration Sep 14 04:50:50 pfn can i export the module as a library project? seems it stripped my intellij project Sep 14 05:04:25 a lot of sdk sample can not be built on Android Studio Sep 14 05:36:31 Good morning everyone. Sep 14 05:37:31 ffs how long does it take the gallery app or any other content provider to realise that a resource/file is not there Sep 14 05:38:44 Lorenz9 morning, 6.38am here :) almost bed time Sep 14 05:39:10 7:38 here! Still awake or just woke up? haha Sep 14 05:39:20 still Sep 14 05:39:57 fighting with things that I neither comprehend or have any real means to solve :) Sep 14 05:41:57 I also have a tendency to stay awake at night doing shit Sep 14 05:42:11 I try to avoid it though Sep 14 05:42:44 In fact I never really wake up at this time of the day, it's just that I couldn't sleep :P Sep 14 05:42:55 So watcha worried with? Sep 14 05:44:16 mms and t-mobile Sep 14 05:44:27 the last problem I have left to fix Sep 14 05:44:38 but quite a large problem it is Sep 14 05:44:54 should be fairly immediate stingray Sep 14 05:45:18 not sure I follow ? Sep 14 05:45:29 "ffs how long does it take the gallery app or any other content provider to realise that a resource/file is not there" Sep 14 05:45:44 lasserix oh that, yeah mine does not..been hours Sep 14 05:45:46 that question doesn't make sense to me Sep 14 05:45:49 nexus 5 4.4.4 Sep 14 05:46:00 can you be more specific Sep 14 05:46:11 did you register a content observer? Sep 14 05:46:13 well I delete an image with ES file manager Sep 14 05:46:29 the gallery app still lists it Sep 14 05:47:35 not a massive issue, just didn't know I would have to account for it thats all Sep 14 05:47:41 mine does it automatically Sep 14 05:47:56 just took a picture, switched to es file, deleted it, switched back and it was gone Sep 14 05:47:56 nexus 5 ? stock ? Sep 14 05:48:07 yeah Sep 14 05:48:33 crap… cheers for testing… going to have to re-flash/reset or something Sep 14 05:48:47 well cool, that just leaves this huge mms problem :) Sep 14 05:49:07 what's your mms problem? Sep 14 05:49:28 well just with 1 carrier T-Mobile US Sep 14 05:49:37 I get a 400 response fail Sep 14 05:49:54 but no meaningful info why Sep 14 05:50:10 or rather the logs that would show why are obviously server side Sep 14 05:50:45 ahh Sep 14 05:51:14 and I could spend a day or so blind shooting to figure it out, but 1, not on t-mobile and 2. not in the US Sep 14 05:51:38 2 quite big problems there …. hence the questions about adb through ssh tunnels earlier Sep 14 05:53:05 quite good, already have users that are willing to allow me access to their own machines to have a go at solving it….1 even phoned t-mobile as a customer with a list of questions about it :) Sep 14 05:53:11 * StingRay_ was touched Sep 14 05:54:07 ah, remote diagnostics Sep 14 05:55:22 ever tried it g00s ? Sep 14 05:55:33 I would have thought things like this would be common now Sep 14 05:55:47 or some tools would exist to make it … possible Sep 14 05:56:16 StingRay_ does crashlytics have some tools for this ? Sep 14 05:56:33 not that I'm aware Sep 14 05:56:45 hm Sep 14 05:57:07 nice product suggestion though :) Sep 14 05:57:24 i thought you were using it O.o Sep 14 05:57:54 crashlytics yes Sep 14 05:58:31 I mean a product suggestion for the team, remote rt-debug tool Sep 14 05:59:57 the only thing i have atm is a preference burried to enable diagnostics and email me a file Sep 14 06:02:47 which is kinda lame ; should look into something better Sep 14 06:07:39 crashlytics sucks, it doesn't have any tools... Sep 14 06:08:17 StingRay_ and the problem is on a user's phone, and you're trying to get more info on it Sep 14 06:08:49 problem is outlined in the logs on the server Sep 14 06:08:57 that I have not a chance in hell of getting to Sep 14 06:09:06 logs on the server ? Sep 14 06:09:25 yeah, there will be a detail of the accept deny error on the mmsc Sep 14 06:09:38 just not given in the error response Sep 14 06:10:10 so I wanted a users phone on the network to just start and try 101 things to see if I could get anywhere Sep 14 06:14:13 the closest i ever came to remote instrumenting / logs was to have mqtt client in the app which talked to test.mosquitto.com; all the logs were intercepted and thrown there. you can subscribe to that device and read them, and issue commands Sep 14 06:14:38 test.mosquitto.org Sep 14 06:15:20 what i did as i wrote a slf4j wrapper around mqtt basically Sep 14 06:15:59 the logs that I have or can have access to are not going to help much, it's more a machine gun approach to various attempts I would fire at the server to test responses. Something that is not realistic unless I'm attached to the device :( Sep 14 06:16:00 then in the app you have a tree of commands like /command/mms/create Sep 14 06:16:16 cause I just dont know what I would be looking for Sep 14 06:16:29 well yeah, you need to issue a command to yout app Sep 14 06:16:42 so in that case, you send the command to the mqtt broker , and your app listens for it Sep 14 06:16:52 well anyhow, i never finished it Sep 14 06:17:02 not something anyone is going to whip up in a weekend Sep 14 06:17:16 but i probably should finish it Sep 14 06:17:33 really I need to speak to mmsc server admin at t-mobile, ask them what they have changed Sep 14 06:17:52 it's only in the last 2 months Sep 14 06:18:06 maybe their plan is f'd :D Sep 14 06:18:39 plan ? Sep 14 06:18:53 phoen plan, could they have dropped texting messaging ? Sep 14 06:18:56 *phone Sep 14 06:19:26 i mean, could they have a plan with voice and data, but no texting ? Sep 14 06:19:33 is it for everyone using tmo ? Sep 14 06:19:39 oh this is not a single user Sep 14 06:19:46 it's all users of my app on T-Mobile Sep 14 06:20:59 but annoying that it's "just" t-mob Sep 14 06:21:11 so far :) Sep 14 06:21:33 StingRay_ for an app like this, it might be good using some testing service Sep 14 06:21:43 if only Sep 14 06:22:00 already spent way too much on it Sep 14 06:22:34 half a mind to take a holiday over there and get a phone while I'm there Sep 14 06:22:36 :) Sep 14 06:23:43 I have high hopes for this ssh tunnel stuff though Sep 14 06:23:55 half way though talking a user on how to set it up Sep 14 06:23:56 ssh tunnel ... to where ? Sep 14 06:24:03 to their phone Sep 14 06:24:19 coupled to their computer Sep 14 06:24:28 that is on t-mob :) Sep 14 06:25:04 cause there is also a usb > eth product for remote usb connections but not read good things about it Sep 14 06:25:10 oh yeah that reminds me i have to check out mosh Sep 14 06:25:24 but have seen a few (meaning 2) about success on ssh tunnel Sep 14 06:34:17 hm JuiceSSH has mosh support Sep 14 06:38:04 Can someone help me figure out how to send a picture from Android to my django server via POST? I don’t know how I’m supposed to do it Sep 14 06:41:33 misingnoglic thats way too broad , what specific issue are you having ? Sep 14 06:41:51 * StingRay_ asks that hoping the issue is not "I have not learned anything about it yet" Sep 14 06:42:23 hmmm I will swap you problems, I have a POST problem too :) Sep 14 06:42:35 anyone introduce me a android book for beginner? Sep 14 06:43:14 StingRay_: So I’m at a hackathon working with an android guy, and he’s trying to send me an image as a byte array output string Sep 14 06:43:19 but it gave him a memory error Sep 14 06:43:38 it’s just a simple POST thing and I doubt it should be this complicataed Sep 14 06:43:50 I read if you are using bitmaps for a canvas, you should decode them in onResume and recycle them in onPause, can't you just decode them in oncreate? Sep 14 06:44:23 It’s a picture from the camera if that helps Sep 14 06:44:50 misingnoglic so you are sending maybe 4mb of base64 string ? Sep 14 06:45:14 yeah Sep 14 06:47:26 it was going at like 80 megs tho Sep 14 06:47:46 misingnoglic: what class you using to post? Sep 14 06:48:24 we were trying to use byte array output string Sep 14 06:48:27 but that didn’t work Sep 14 06:48:41 but I’m not sure how else it’s supposed to be handled Sep 14 06:48:44 no i mean to do the post Sep 14 06:52:22 http://pastebin.com/MU37KaXM Sep 14 06:52:30 here's how i do a put with a json object Sep 14 06:52:35 have tested it up like 100 mb works Sep 14 06:52:58 tho a lot of people will tell you to use okhttp which you probably should ;p Sep 14 06:53:03 use okhttp Sep 14 06:56:34 haha Sep 14 07:19:14 the more i have to deal with fragments and activities the more i want to say fuck it and just use raw views Sep 14 07:30:43 C'mon, you're at least halfway there! Sep 14 07:32:58 desmin88 i thought you were going to try that mortar library Sep 14 07:33:09 yeah Sep 14 07:34:00 do eeeet ! Sep 14 07:40:28 My favorite is the activity <-> fragment onBackPressed bullshit Sep 14 07:40:30 such a pain to handle Sep 14 07:49:44 mortar has nothing to do with using raw views Sep 14 08:00:24 Hi, i am playing with fragments + activity tabs. When i close the main activity there is no problems. But when i close a fragment by doing fragmentManager.popBackStack(); and fragmentManager.beginTransaction().remove(fragmentManager.findFragmentByTag(actionBar.getSelectedTab().getText().toString())).setTransition(FragmentTransaction.TRANSIT_FRAGMENT_CLOSE).commit(); The fragment do OnDestroy() and OnDetach() so maybe it worked ..? But in t Sep 14 08:26:54 JakeWharton: it atleast helps you use raw views though, right? Sep 14 08:27:02 no Sep 14 08:27:07 oh Sep 14 08:27:13 then im dumb Sep 14 08:27:45 you can use it with raw views, fragments, activities, whatever Sep 14 08:27:53 oh Sep 14 08:27:59 my god Sep 14 08:28:16 why is it that in 21st century we still have no decent locale change support in API Sep 14 08:28:51 i thought it was limited to primarily raw views, but thats neat it can do more Sep 14 08:30:47 i guess they want the app's ui to be the same as systems locale wise Sep 14 08:31:15 Mavrik: because the International failed... Sep 14 08:33:27 -_- Sep 14 09:05:25 Hi, how can i get rid of spelling checking with a underline red line in Intellij Idea? Sep 14 09:13:17 I'm trying to make a list view with items that expand to show more data when clicked Sep 14 09:13:32 My first thought was expandable list view but that's an array of children Sep 14 10:00:25 Hello there. I want to implement In-app billing for my application. I got that part ready, but i want to make the app download additional files that are unlocked when the purchase is complete. Is there a way to do that from a google service? I got no idea how to achieve that. Any help? Sep 14 10:04:00 Hey, there's a website that showcases a lot of open source custom views or UI elements, I cant seem to find it, do you know it? Sep 14 10:06:21 android arsenal perhaps? Sep 14 10:10:19 something similar.. Sep 14 10:10:38 i need to do some sort of absolute positioning Sep 14 10:10:57 so if you see this - http://puu.sh/byrRz/14dc98fda0.png - I want to position the chckbox at the top of the list item, not below the last view. Sep 14 10:11:00 is that possible? Sep 14 10:11:21 i thought of giving negative margin, but then i dont think it'll stand out at the top as it'll depend upon the content of the other 2 textviews Sep 14 10:11:43 um, yeah, that's not HTML for negative margins to work Sep 14 10:11:54 shmoon_, relatve layout, alignparent right and that's it Sep 14 10:12:09 alignparentleft and below for the two textviews Sep 14 10:12:15 or just use two nested linearlayouts Sep 14 10:14:44 ok this was easy, just had to use a relativelayout and not linearlayout Sep 14 10:14:46 thanks Sep 14 10:21:13 so i added checkedtextview in a listview with choice_mode_multiple. now on tapping the checkbox i wanna make it check/uncheck and later take the items selected and do something with it. Sep 14 10:21:18 some pointers? Sep 14 10:22:48 there must be some event on the listview called when an item is checked/tapped in multi selection mode? Sep 14 10:25:17 Not really, ListView just calls setChecked on the View Sep 14 10:25:28 setActivated if it's not Checkable Sep 14 10:26:26 ok Sep 14 10:26:36 will have to manage in the code then Sep 14 11:25:29 hi all. if i wanted to create a camera app with filters like instagram - will using OpenCV be an overkill? Sep 14 11:35:32 my OnClickListener won't fire. I have many customviews and I am accessing statically elsewhere in my fragment. given a condition I want to add an OnClickListener but I can't get a reference to the activity's context Sep 14 12:04:46 Hi everyone. I am quite new to Android dev but I have experience in C/C++ and also some with Java. I wanted to know if there are any PDF/tutorials I could follow in order to get experience / learn android developpement Sep 14 12:18:04 thms: google Sep 14 12:19:10 MartialLaw: I already done that but there are plenty of tutorials.. just wanted to know if there is a reference or well known course that I could follow, possibly with projects I could import into Android Dev Studio and play around with them. Sep 14 12:27:22 vogella is good Sep 14 12:27:57 http://www.vogella.com/tutorials/android.html Sep 14 12:34:50 is there a way to check listview items apart from using position Sep 14 12:35:03 i actually have a search box involved Sep 14 12:35:11 I'm trying to define a global string variable into @string. But when I use R.string.var_name, an error occurs saying that that line returns an int value instead of String. Does R.string returns an int value ? If yes, do I need to set Integer.toString(R.string.var_name) to get as a string ? Sep 14 12:35:15 so it messes up when i search and then check and clear the earch Sep 14 12:35:21 then incorrect items get checked due to positions Sep 14 12:35:43 nectarys: https://developer.android.com/guide/topics/resources/string-resource.html#string-element Sep 14 12:37:35 is there any one who can run android desktop on docket container? Sep 14 12:37:43 MartialLaw: Thanks :) Sep 14 12:47:50 hi -how do I get junit4 tests to run in android studio? Sep 14 12:48:03 I can't seem to find anything up-to-date on getting the tests to work Sep 14 12:49:19 heloo Sep 14 12:49:28 anybody have worked on payment gateway Sep 14 12:50:20 i need to provide interface in my app through which i can transfer some money from my account to another one Sep 14 12:50:33 but in secured way Sep 14 12:50:46 i have never developed this kind of app Sep 14 12:52:47 Hello there. I want to implement In-app billing for my application. I got that part ready, but i want to make the app download additional files that are unlocked when the purchase is complete. Is there a way to do that from a google service? I got no idea how to achieve that. Any help? Sep 14 12:55:31 Hello, I'm trying to create an application which uses live feed from camera as a background. I have another surfaceview which is drawing to canvas. I have both views in xml layout file where the camera's surfaceview is above the other view. When I start the application it quickly shows the other view and then puts camera preview on top of that. I have tried using bringToFront() function but to no avail. Pastebin to relevant cod Sep 14 12:57:50 What I have found from google so far is that you can decide the view order in layout file, where you put the top view below the background view Sep 14 12:58:43 But I have done that. The other method was to use bringToFront() function for the view which is desired to be in front but that doesn't work either Sep 14 13:03:18 Tobiski, SurfaceView is special (which is explained in the doc) Sep 14 13:03:29 it is not part of the view hiearch Sep 14 13:03:44 it can draw OVER everything or it can be UNDER everything - you can't sandwitch it in Sep 14 13:04:03 you can stack couple of them one over another but they still have to conform to that fact Sep 14 13:07:38 Mavrik: but I have only 2 views, one on the background and one in front. And I don't need to change the order of views at runtime Sep 14 13:08:12 I'm trying to but the camera view under everything but so far with no luck with the methods I mentioned above Sep 14 13:08:32 *put Sep 14 13:10:00 Tobiski: first google result: http://stackoverflow.com/questions/2933882/how-to-draw-an-overlay-on-a-surfaceview-used-by-camera-on-android Sep 14 13:10:38 Tobiski, setZOrderOnTop(false) Sep 14 13:12:04 bourbon: I have found that and have done what the first answer says, but the camera view goes on top regardless Sep 14 13:13:06 dunno what you're doing wrong, then Sep 14 13:13:15 I've never had issues stacking UI on top of a camera preview surfaceview Sep 14 13:14:18 have you done anything with z-ordering? Sep 14 13:16:48 when i switch orientation the video in my videoview starts over, how can i prevent this? Sep 14 13:19:25 bourbon: I haven't. I need to try again with fresh eyes later and maybe spot where I did wrong Sep 14 13:24:26 I'm getting this uncaught exception, can someone help me debugging it? Sep 14 13:24:27 http://pastebin.com/L9ZDvU1a Sep 14 13:24:48 Got i!. Mavrik thanks for that function. I also had to set format of the handler to transparent. But it works now Sep 14 13:26:33 Glitches: https://developer.android.com/reference/android/os/NetworkOnMainThreadException.html Sep 14 13:26:42 "The exception that is thrown when an application attempts to perform a networking operation on its main thread." Sep 14 13:26:54 Just don't do that Sep 14 13:26:56 oh... Sep 14 13:27:24 alright, Thanks! Sep 14 13:28:15 How to use getString() and getApplicationContext() via one helper class, please ? Sep 14 13:32:22 How to use getString() and getApplicationContext() via one helper class, please ? Sep 14 13:36:59 anyone strong in patterns?... having 5 classes implementing a interface.. and having a different class just working with the interface.. and as such dynamically be able to work with all 5 classes and treat them as one Sep 14 13:37:06 is that strategy pattern? Sep 14 13:37:14 or is it factory.. Im confused Sep 14 13:38:48 How to use getString() and getApplicationContext() via one helper class, please ? Sep 14 13:39:07 nectarys: Please do not spam your question Sep 14 13:39:08 getString on what? Sep 14 13:39:23 Ask and wait 15-30 minutes. If no answer, ask again Sep 14 13:39:46 if you need a sub class to retrieve information it doesn't have.. like textView.getString() ... you need to pass it along to that class/method Sep 14 13:39:59 public HelperClass (TextView tv) Sep 14 13:40:20 get it from your xml, and pass it to the method or constructor Sep 14 13:40:25 and then have it retrive information there Sep 14 13:42:26 is that what you are asking? Sep 14 13:53:00 I'm using google analytics and added an event. is there a way to test this manually on my local machine's emulator and check out the generated reports? Sep 14 13:53:43 ebay down? Sep 14 13:54:46 GEEGEEGEE: seems so. cant login too Sep 14 13:58:43 should I just use a different profile? Sep 14 14:05:33 how does List var = new ArrayList; help over ArrayList var = new ArrayList; ? Sep 14 14:05:39 siilarly with Set and HashSet ? Sep 14 14:05:59 shmoon_: ArrayList implements List Sep 14 14:06:06 so yes Sep 14 14:06:24 yeah but I could just do the latter? Sep 14 14:06:29 most examples contain former that confuses me :S Sep 14 14:07:08 you can do both.. Sep 14 14:07:12 it doesnt really matter Sep 14 14:07:45 ok thats whar I wanted to know, doesnt really matter :D Sep 14 14:08:23 if you do the first, youll only have access to methods defined in List, not the ones from arraylist Sep 14 14:09:01 can I dynamically display a frame or something on an ImageView.. like imagine I want someone to click a picture and if they click the right one.. I want it to get a frame of light green Sep 14 14:09:02 but it doesnt really matter in this case since you rarely see any methods in arraylist that are not in List Sep 14 14:09:16 um but the version of the method used willbe the overridden one from arraylist, right ? Sep 14 14:09:58 hmmm I suppose I could use padding and set a background color Sep 14 14:09:59 ? Sep 14 14:10:02 I'm talking to myself Sep 14 14:10:05 got it..thx P3nnyw1se Sep 14 14:10:09 no problem Sep 14 14:10:10 shmoon_: classic java inheritance :) Sep 14 14:11:28 java.util.List is an interface, so it only defines method stubs. Sep 14 14:11:39 that are implemented in arraylist then. Sep 14 14:12:21 but if arraylist would define some method that has not been defined in List interface, and you'd do List list = new ArrayList(), you couldnt use that method afterwards without casting list to arraylist Sep 14 14:12:31 ok thank you Sep 14 14:12:31 because your code dont know its an arraylist then Sep 14 14:43:04 List = ArrayList is advisable over ArrayList = ArrayList because interface usage is preferred over a specific implementation usage, unless the specific situation calls for specific implementation usage; basically once the object is created you're not supposed to know or care about the implementation and only use what the interface gives you Sep 14 14:47:52 if making a request for 45 items to a database, do I have to do that on a background thread? Sep 14 14:49:11 sweltch: Is it over network or local? Sep 14 14:49:20 if it's network then you have to Sep 14 14:49:21 any network databasing.. yes definetly Sep 14 14:49:38 How to use getString() and getApplicationContext() via one helper class, please ? Sep 14 14:49:44 actually Glitches Sep 14 14:49:49 you dont have to.. you should.. :P Sep 14 14:50:02 P3nnyw1se: You can't start network processes on the main thread Sep 14 14:50:09 so you have to Sep 14 14:50:20 hmm pretty sure I did it once in a singleton.. will look Sep 14 14:50:26 nectarys..you just keep spamming that question Sep 14 14:50:32 I answered it 20 minutes ago Sep 14 14:50:38 or tried too..you never gave feedback Sep 14 14:50:43 P3nnyw1se, what was you answer please ? Sep 14 14:50:56 P3nnyw1se, I think that I haven't seen that, sorry ! Sep 14 14:51:08 you have what like a textview .. and you want a help class to get the text in it? Sep 14 14:51:22 Glitches, no it is local Sep 14 14:51:42 sweltch: Then you don't have to Sep 14 14:51:46 nectarys, your question doesn't make much sense, either elaborate or post some code Sep 14 14:51:50 won't make a difference Sep 14 14:51:54 Glitches, but should I? Sep 14 14:52:04 sweltch: Yes, you should Sep 14 14:52:06 P3nnyw1se, I'm just tried to set some helper methods on another class, which can parse @string into strings using getString and get the current context of the application Sep 14 14:52:07 everyoen says I/O on main is bad Sep 14 14:52:28 sweltch, the number of records is irrelevant, if whatever you're doing slows down or freezes the UI noticeably then you should Sep 14 14:52:29 nectarys.. if you want another class to work with information that the first class has.. Sep 14 14:52:37 it's just a matter of common sense Sep 14 14:52:39 you need to pass it to the other class.. eg. in the constructor Sep 14 14:53:03 like lets say you have a TextView and you want another class to deal with it Sep 14 14:53:29 new ClassName(textView) ... you get the textView .. Sep 14 14:53:36 pass it to the other class.. and let it deal with it Sep 14 14:53:45 P3nnyw1se, there is not another possiblity to deal with ? Sep 14 14:53:48 no Sep 14 14:54:08 well there is a silly way Sep 14 14:54:16 actually no Sep 14 14:54:18 ravilov, but, by extending Activity class, that works Sep 14 14:54:37 yes but an extended activity is not a "helper class" Sep 14 14:55:12 if the AsyncTask produces a result, what is the best way to communicate this to a fragment, via global variables? Sep 14 14:55:28 I would definetly pass it to the other class.. in methods or constructor Sep 14 14:55:39 sweltch, invent a callback, like MainActivity.onDataReady() or something Sep 14 14:56:00 ravilov, then how to use startActivity from a helper class ? Sep 14 14:56:46 nectarys, if a "helper class" is in fact what it's supposed to be, then like P3nnyw1se is telling you Sep 14 14:57:48 if you pass an argument of huge size is Java smart enough not to pass the whole thing but rather a reference to it? Sep 14 14:58:08 java *never* passes arguments by value Sep 14 14:58:15 unless it's of a primitive type Sep 14 14:58:34 (this is something that could have been easily googled) Sep 14 14:58:34 what you can do is.. set a new object to it Sep 14 14:58:34 in fact, I'm trying to define a class for MenuItem methods to make them more maintainable. isn't the best way to deal with ? Sep 14 14:58:57 set the reference to a new object and use that object Sep 14 14:59:16 nectarys, you're too vague, it's hard to tell if what you're doing is the best way or not Sep 14 14:59:57 why would you ever want to use startActivity from a helper class Sep 14 15:00:20 because he wants his menu items to start activities Sep 14 15:00:28 MainClass -> send info -> Helper ..... Helper -> Reponse -> MainClass ... MainClass(do the work) Sep 14 15:01:01 what.. seems to be the officer? ... problem... Sep 14 15:02:34 nevermind the fact you can assign intents to menuitems straight in the xml ;) Sep 14 15:02:42 whats the rule of a public static variable, if it has been assigned a value and then it is assigned null, when will that old structure be GC:ed? Sep 14 15:02:56 P3nnyw1se and ravilov thank you so much ! Sep 14 15:03:36 Even I had lke no idea of that ravilov.. and I used android for like a few weeks Sep 14 15:03:40 which in programming is a lifetime Sep 14 15:04:17 sweltch, any object that's reference count is gone to zero will be a GC candidate. what do you mean by "the rule"? Sep 14 15:04:51 I dont understand that question, but its interesting Sep 14 15:05:10 arent you talking about overwriting a válue? in that case the old value should be garbage collected right away Sep 14 15:07:49 In order to update client side sqlite database, i need to send some amount of json data to the phone. To reduce the failures&retries with bad connection, i want to split the data into multiple calls each containing some of the database rows to update. Does anyone have experience on what is a good size of chunks? Sep 14 15:09:14 no option on just syncing the database on the client on startup? Sep 14 15:09:43 if there's going to be connectivity issues, it can happen with any chunk size Sep 14 15:10:29 ravilov: yes but the chunks arent dependent on each other. so if i have 10mb of data, and can split them into 1 mb the chance of connection timeouts is smaller Sep 14 15:10:40 and the user can work with 10% of the data :) Sep 14 15:10:57 in that case, can the user work with 0% of data? :p Sep 14 15:11:02 also update on startup is not an option. I need it as a service doing it in background Sep 14 15:11:16 ravilov: no.thats the point :) Sep 14 15:11:43 if i need to update the info on 1000 rows, and it fails, the data of 1000 rows is old Sep 14 15:12:11 if i do it in packs of 100 rows part after part, the operation has a better option to succeed Sep 14 15:12:53 no I get your point, but I'm used to work with transactions (either everything fails or nothing fails), so I don't understand how can having just a fraction of the data be acceptable :) Sep 14 15:13:05 working* Sep 14 15:13:18 ravilov: its acceptable if the data doesnt depend on each other Sep 14 15:13:56 for example thing of a database containing wikipedia entries. It doesnt matter if entry X is 1 week old or not if you want to view entry Y Sep 14 15:14:00 think* Sep 14 15:15:09 dunno, I guess you could try splitting it up into logical chunks, whatever their size Sep 14 15:15:39 thats what i want to do. Im just thinking of what would be a good number for chunk size Sep 14 15:16:30
