**** BEGIN LOGGING AT Sat Mar 09 02:59:59 2013 Mar 09 04:03:16 wondering if someone can tell me how to switch between tabs in a "tabcontent". I added a listview, an expandablelistview, and a searchview. At application launch, only the searchview is shown Mar 09 06:29:26 hi there. someone can suggest to me a good tutorial in order to learn to create an android application in a correct way? Mar 09 06:30:53 jewels: http://developer.android.com/training/index.html Mar 09 06:31:30 do you think that it is enough for study it completely? Mar 09 06:32:24 completely ? Mar 09 06:32:38 you probably need 2-10 years for that Mar 09 06:32:50 and even then, there will be missing things Mar 09 06:32:52 :) Mar 09 06:33:50 :) Ok you're right. I just want to read a well written tutorial which will give me a good base in order to write android application which could be runned with different android version Mar 09 06:34:12 is it possible? Or for each version of android I have to create an appropriate android application Mar 09 06:34:39 You know, I'm a newbie, and I'm here just for asking some question about android world :) Mar 09 06:34:56 jewels: I think you should read the training stuff I just linked Mar 09 06:35:09 and then come back with any questions you may have Mar 09 06:35:16 cause most of it is covered in there Mar 09 06:35:47 that's ok :) Mar 09 06:36:07 can you give me some suggestion before I start? Mar 09 06:36:14 on what ? Mar 09 06:36:48 on android application, on the paradigm that I have to use in order to create correct one and well structured. Mar 09 06:36:53 does anybody know a great tutorial on Context.getcache()? Mar 09 06:37:00 usually i just use ormlite Mar 09 06:37:02 jewels: read that link Mar 09 06:37:07 but i'm wondering what the best approach is Mar 09 07:26:36 how you doing StingRay_ Mar 09 07:26:42 so so Mar 09 07:26:57 did TheBunny get you ? Mar 09 07:27:03 wondering why there are such major diffs in android versions Mar 09 07:27:11 like data source sh*t Mar 09 07:27:14 like contacts Mar 09 07:27:16 ugh Mar 09 07:27:22 the what get me? Mar 09 07:27:29 oh, the ContentProviders ? Mar 09 07:27:42 yeah the common data crap only added in 11 Mar 09 07:27:54 single query for multiple sources I like Mar 09 07:27:59 just why not < 11 Mar 09 07:28:09 who was after me ? Mar 09 07:28:25 there are parts of the api i won't mess with. that and stuff like MediaPlayer ;) Mar 09 07:29:07 who is TheBunny and what did they want with me ? Mar 09 07:30:12 na, i was just joking because of your bunny video Mar 09 07:39:00 StingRay_: i have a feeling i am going to stay up all night so i can leave here around 4 to get up to the mountains for pre-dawn landscape picture. not really sure its worth it with my crappy camera, the result won't be amazing from IQ perspective Mar 09 07:39:52 * g00s loves it when there is snow in the desert though Mar 09 07:41:48 g00s: where are you ? Mar 09 07:42:10 arizona Mar 09 07:46:20 StingRay_: here is a pic i took today. not only is my p&s crappy, but i had 2 water drops on the lens :( http://i.imgur.com/UIzxiCb.jpg Mar 09 07:46:34 maybe it has some potential after i learn more LR Mar 09 07:47:15 you cam is not 4:3 ? Mar 09 07:47:34 your* Mar 09 07:47:40 i forgot actually. i thought 3:2 Mar 09 07:47:50 really? Mar 09 07:47:54 i prefer 1:1 and 4:3 Mar 09 07:48:02 not for landscapes Mar 09 07:48:05 surely Mar 09 07:48:12 i think 3:2 sucks for verticals Mar 09 07:48:49 need a nice widescreen for landscapes Mar 09 07:49:24 oh, this powershot g9 is also like 35 mm Mar 09 07:49:46 i'd like minimum 28mm, 24mm would be nice Mar 09 07:49:54 still, I would frame and crop to 19:9 Mar 09 07:49:57 oops Mar 09 07:50:00 16:9 Mar 09 07:50:33 the water droplets on the lens must have done something, maybe global blur :| Mar 09 07:50:55 loss in contrast? maybe. wish i knew more about optics Mar 09 07:51:49 would have been nice to have a polarizer to make the rainbow stick out more ;) Mar 09 07:53:50 I have a variable ND somewhere Mar 09 07:53:55 I think Mar 09 07:54:00 cool Mar 09 07:54:02 dont think I've ever used it Mar 09 07:54:04 lol Mar 09 07:54:20 this camera can't take any filters Mar 09 08:35:59 you cum lol Mar 09 08:48:27 Hi, I'm looking for some general advice, I'm a full time student (not a business) so when I'm trying to set up an amazon store account I'm not sure how to handle the tax section? Mar 09 09:07:12 hi all Mar 09 10:07:01 * g00s looks at the svn project page to see whats happened in the past few years; seemingly little Mar 09 10:40:41 hello Mar 09 11:13:13 anybody here moved away from jquery mobile? Mar 09 11:13:33 to say https://github.com/EightMedia/hammer.js or something.. curious about y'all input Mar 09 11:14:32 was reading http://codemint.net/stop-using-jquery-mobile/ and http://blog.siami.fr/articles/why-i-hate-jquery-mobile ... not good :( Mar 09 11:37:02 boytoy: use senchatouch, but to be honest, every of this frameworks have their own issues Mar 09 11:38:32 Could also just make apps ;d Mar 09 11:54:09 i am pretty curious about Enyo Mar 09 12:09:57 Hi. I am using the theme android:theme="@android:style/Theme.Holo.Light" for the whole application. If I add ScrollView to my activity, the actionbar is suddenly all #ffffff as if I lost the theme. Any ideas? Mar 09 12:45:17 I need to get the date format string (i.e. "MM/dd/yyyy" or "dd. MM. yyyy") that is used by the current locale. An instance of DateFormat that uses this format string does not work, I need the string itself. Any ideas? Mar 09 12:47:14 i dont think you can get it. the framework has a private resource for each locale Mar 09 12:47:31 DateFormat and that class cluster - is a cluster fuck Mar 09 12:48:19 damn :( Mar 09 13:19:05 question guys i have code examples of using scribe-java library with android to authenticate it with facebook,linkedin, twitter,... and also examples of how to retrieve stuff (messages) and post messages Mar 09 13:19:18 i want to post this somewhere so people who want to use it for android are able to easily find it.. Mar 09 13:19:22 anyone have a suggestion? Mar 09 13:26:46 github Mar 09 13:26:51 google code or github Mar 09 13:27:02 Also, post it somewhere that people might find the link Mar 09 13:27:50 Like here, github etc Mar 09 13:28:00 reddit* Mar 09 13:28:04 not github hahaha Mar 09 13:41:18 hei guys ... if one downloads a free app from the market..then uninstalls it then installs it again, does that register as two installs? Mar 09 13:41:22 even if it's by the same user? Mar 09 13:41:40 no Mar 09 13:41:47 anyone here do both android and ios? Mar 09 13:42:58 but if i install the same app from my same google account on two different devices...does that register a 2 installs? Mar 09 13:43:12 Nope Mar 09 13:43:20 It counts as 2 active installs Mar 09 13:43:31 And 1 total installs Mar 09 13:43:42 great Mar 09 13:44:26 oh, that might explains why some of my apps have had a weird install/active install count in the past Mar 09 13:56:08 So I have the same instance of an ontouchlistener for two objects. If the user drags his finger in one object, at the edge the ontouchlistener stops. How can I continue this across the two objects? Mar 09 14:10:39 Your view should continue to get touch events, even if the pointer leaves its bounds, until you get an UP event or you return false Mar 09 14:11:02 How do I stop gingerbread from murdering my innocent little dd process? As a test, I have him appending several gigs of /dev/zero to /dev/null and he gets auto-killed by android itself (not an app). Nice'ing it doesn't seem to help. I might be able to workaround by doing it in small increments but would rather avoid that. Mar 09 14:12:16 SimonVT: I think it was because I was returning false early. Anyhow I can see it going past the view now! Thanks Mar 09 14:20:56 Do setColor paint events happen once a motion event is complete? I'm trying to do a touch event where as I drag my finger the background increasingly goes from black to red. It seems to be set once the action up occurs. Mar 09 14:22:14 Like.. Paint#setColor? Mar 09 14:22:17 There's no event Mar 09 14:22:27 You're just setting a variable Mar 09 14:22:41 You have to invalidate the view if you want it to redraw Mar 09 14:23:17 SimonVT: Ah so I have something like .getPaint().setColor((int)(originalColor)) in the MotionEvent.Action_Move Mar 09 14:23:32 So I would have to invalidate it to update during the movement? Mar 09 14:26:26 Awessome, that seems to be closer to what I want Mar 09 15:03:52 I have a touch event on an item in a linearlayout that is part of a scroll view. Is there a way to catch the event when I leave the linearlayout? I want to pretend like I lifted my finger yet still do the scroll. Mar 09 15:08:22 good morning, I was wondering what the preferable means of manage FragmentDialogs and AsyncTasks is, baring in mind the activity lifecycle Mar 09 15:09:32 noteably, if an AsyncTask may or may not require a dialog to be displayed, how should one deal with showing the dialog if the call is made mid-rotation of the device, and equally for dismissal Mar 09 15:10:22 it feels like the correct approach would be to subclass AsyncTask to make it aware of the lifecycle, and then cache changes to the dialog until the activity is in a suitable state? Mar 09 15:13:01 well, one way around this is to use a service to execute your asynchronous tasks. The service fires a sticky broadcast once completed, your activity listens to broadcasts and may perform actions when receiving broadcasts. Mar 09 15:14:41 that is interesting, is there any advance to that over a lifecycle aware asynctask? Mar 09 15:14:48 advantage^ Mar 09 15:16:23 the service does not need to handle any lifecycle events and is only loosely coupled (good thing) with your activity. Mar 09 15:16:48 good point Mar 09 15:17:50 Figured out my question. Lesson: tons of pipe i/o creates enough cpu usage to get your process autokilled Mar 09 15:17:57 haven't used AsyncTask yet though, so cant tell if AsyncTask provides better ways to solve your problem Mar 09 15:18:07 You're guaranteed that no callbacks are made between onDestroy and onCreate.. As long as you properly handle passing the asynctask to the new activity instance, you should be fine Mar 09 15:18:14 the service approach is what i'm using within my application and it works quite well. Mar 09 15:20:00 simon thats the thing though, if the asynctask is trying to show a dialog in the UI thread, you have no guarantee that the activity is in a suitable state to attach it Mar 09 15:20:59 optic my concern with services is they seem more appropriate for situations where you either want to share data, or provide ongoing capabilities without need for a UI Mar 09 15:24:19 When would the activity not be in a suitable state Mar 09 15:25:25 my example would be an AsyncTask which handles obtaining some data, which may or may not be located on a remote server,and may or may not already be cached, you have a function available to prepare the data to be displayed, and a listener which provides progress on any download (if it was required) while that function is executing. The AsyncTask starts up, initializes the class responsible for the data, and attaches the listener and t Mar 09 15:25:48 hmm Mar 09 15:25:56 i would then pass those details to the UI thread as progress, and at that point i would wish to open a FragmentDialog to display a progress bar Mar 09 15:26:02 i've got some asyntasks Mar 09 15:26:07 that grab stuff from twitter for example Mar 09 15:26:21 thats than pushed into a static user object in the mainactivity Mar 09 15:26:57 the asyntask has "onprogress" function to update taht sort of thing if you do n't know how much % it is just a spinner loading bar with text saying what you are doing and maybe which number it is Mar 09 15:27:11 like logging in 1/7, validating data 2/7 .. etc Mar 09 15:27:25 yer im using that to pass the progress to the UI thread already Mar 09 15:27:33 robb_www if you want to update UI thread stuff you'll need to do it @ onpostexecute etc Mar 09 15:27:42 no, onprogress is also UI thread Mar 09 15:27:59 yes i know but you don't really use that to push real data :p Mar 09 15:28:13 its not data, its state Mar 09 15:28:17 yea :) Mar 09 15:28:20 i.e. download occuring, 50% Mar 09 15:28:36 I still don't see the issue.. Your activity is destroyed, at which point you detach it from the asynctask.. When the new one is created, you attach that Mar 09 15:28:39 You know what state it's in Mar 09 15:28:57 how is the asynctask detached from the activity? Mar 09 15:29:25 And onprogress isn't going to be called between those two methods Mar 09 15:29:28 ahh, i have a feeling i know what the issue is, i think i might be forming a clojure with the current activity instance :/ Mar 09 15:29:50 why would onprogress not be called? Mar 09 15:30:08 Well, surely your asynctask is a static class that you attach/detach the current activity to, to ensure you don't leak memory Mar 09 15:30:49 yer, thats the problem, im doing that completely wrong, right now its an inner class in the activity and refers directly to member variables Mar 09 15:30:56 Because the framework ensures no messages are delivered between ondestroy and oncreate Mar 09 15:31:29 When you call postprogress or whatever it is, a message is posted to the main looper which calls onprogress Mar 09 15:31:37 robb_www always use a seperate class :p Mar 09 15:31:39 That message can't be delivered between ondestroy and oncreate Mar 09 15:31:56 ok, my stupidity aside (ill be refactoring that today) a related issue was when i tried to dismiss the dialog onprogress, i would get crashes indicating dismiss could not be called after saving state Mar 09 15:32:48 You sure the activity where you dismissed the dialog isn't the one that just got destroyed? Mar 09 15:32:49 specifically, java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState Mar 09 15:33:05 simon, it probably is, because of this clojure Mar 09 15:33:27 also, it would help if i didnt keep spelling closure incorrectly :D Mar 09 15:34:04 It's unlikely you'll run into this issue if you handle it properly Mar 09 15:34:30 yer this is something ive been unclear on for a while and its made me rather uncomfortable Mar 09 15:34:45 I only tested on a few versions, but a message posted in onpause isn't going to get delivered until after onresume on those versions.. The docs only guarantee ondestroy => oncreate as far as I can see Mar 09 15:35:49 so if this class is separate, is this attachment/detachment automatic or do i have to trigger it manually? Mar 09 15:36:01 Manually Mar 09 15:36:11 hi guys Mar 09 15:36:16 ok, but this isnt done via custom functions in the task, is it? Mar 09 15:36:22 It is Mar 09 15:36:36 hey when i create a class and extend it with surface view Mar 09 15:36:57 then when i call Camera it does't have the open method Mar 09 15:37:01 gives error Mar 09 15:37:03 not sure why Mar 09 15:37:09 any thoughts? Mar 09 15:37:48 hm, so how do i ensure the asynctask is using the correct activity for onprogress? Mar 09 15:38:36 You have a mActivity field.. And you set/unset it Mar 09 15:39:13 You can use onRetainNonConfigurationInstance to pass the asynctask to the new activity Mar 09 15:40:24 in the AsyncTask when i call publishProgress(...) , i dont see how having access to the mActivity helps me ensure onProgressUpdate doesnt run while the activity is paused Mar 09 15:40:33 unless i specifically check to see if ive cleared the mActivity Mar 09 15:40:44 nevermind Mar 09 15:40:46 dumb me Mar 09 15:40:53 On configuration changes, the framework ensures that Mar 09 15:40:56 i imported graphics.camera Mar 09 15:41:06 instead of hardware.graphics Mar 09 15:41:10 oops Mar 09 15:41:16 hardware.camera* Mar 09 15:41:28 so by the sounds of it, the entire problem is purely that my task is an inner class, and forms a closure with the current activity instsance? Mar 09 15:41:40 and if i had not done that, i wouldnt be seeing this behaviour at all Mar 09 15:41:47 Very likely Mar 09 15:41:54 ok, *facepalm* Mar 09 15:42:21 thankyou very much for that help Mar 09 15:42:52 in that case its no wonder if been battling with the API over all sorts of quirky issues Mar 09 15:42:57 ive been^ Mar 09 15:43:27 Well, if you keep doing it wrong, you'll keep having issues :p Mar 09 15:44:09 in the future ill be sure to write my code the right way first time ;) Mar 09 15:48:24 hey guys Mar 09 15:48:44 i got my surface view to show up but the camera isn't on or showing in the view Mar 09 15:48:55 what u think could be the problem? Mar 09 15:54:39 some error about linear layout Mar 09 15:54:51 guess i try relative Mar 09 15:56:10 I don't think GCMRegistrar.register(...) is working any thoughts? (i say this because i keep running the same if statement and i keep getting that isRegistered(...) is false Mar 09 16:12:10 I want to add a custom row in a ArrayListFragment which is inside a FragmentPagerAdapter. I google it but I found nothing relative Mar 09 16:20:23 hi! i have a ViewPager in my Swipe App and i can't get a reference to my fragments. trying to tag them after they get created in the overridden getItem() method with getSupportFragmentManager().beginTransaction().add makes the app crash. i am totally out of ideas. what i want to do i so simple: if user begins to swipe to page 2, recalculate data and display it on page 2. i have set up OnPageChangeListener in my activity already for Mar 09 16:20:23 that purpose Mar 09 16:22:18 SimonVT, removing the closure worked perfectly, fixing this feels almost therapeutic, thanks again Mar 09 16:22:51 the leaked reference must have kept the old message pump going Mar 09 16:26:16 I'm wondering if anyone here knows of an active android development irc channel Mar 09 16:28:28 i think there are a lot of glue sniffers at google Mar 09 16:34:34 when i try to get my camera with Camera.open i get a null pointer exception Mar 09 16:34:45 can anybody think of what might cause it>? Mar 09 16:35:06 my only thought is that the camera can't be accessed Mar 09 16:35:13 i have my manifest right Mar 09 16:35:33 got a FrameLayout allright Mar 09 16:35:40 just won't open the camera Mar 09 16:36:22 anyone know how to get GCM working? I placed all the correct permissions, and I'm calling GCMRegistrar.register(context, mysenderid); and when i try to get the registrationId it's always null Mar 09 16:37:20 Bear10 you need to catch the broadcast Mar 09 16:37:38 xorgate, don't i already do that with the permissions and the class setup in the gettingstarted tutorial? Mar 09 16:39:16 i guess Mar 09 16:39:24 you also enabled it in the google apis? Mar 09 16:39:32 xorgate, yes i do Mar 09 16:40:03 there's the "Project ID:" in my google api but i'm unsure if i need to Register the project Mar 09 16:40:12 doesnt say that anywhere in the getting started Mar 09 16:43:47 for some reason I made a progress bar in my main activity, but I can't reference it's id in another activity...I can reference every other view in my mainactivity in this activity except for the progress bar Mar 09 16:43:59 surface view cannot be cast to framelayout surfaceview android open camera Mar 09 16:44:08 error problem Mar 09 16:44:40 anybody know why i can;t cast surface view with frame layout? Mar 09 16:48:28 Hello i might have a dumb q cause i'm kinda new to java/android dev but i'm having this surfaceview for my ui and in the meanwhile i wonna run a thread for a udp connection but i got no clue how to do this multitheading with the code i have so far ( this is the code https://gist.github.com/anonymous/5124784 ) Mar 09 16:49:38 xorgate, 03-09 17:49:27.471: V/GCMBroadcastReceiver(18833): onReceive: com.google.android.c2dm.intent.REGISTRATION Mar 09 16:49:39 i'm seeing that Mar 09 16:52:31 looks good then? Mar 09 16:52:40 I want to add a custom row in a ArrayListFragment which is inside a FragmentPagerAdapter. I google it but I found nothing relative Mar 09 16:53:52 theodor87 find whatever array is backing the list and update that? Mar 09 16:54:55 No i want to set the rows of the ArrayListFragment from an xml Mar 09 16:55:54 my progressBar's ID isn't showing up in one activity...but it shows up in everything else....whats up with that >:( Mar 09 16:56:00 theodor87 realize that arraylistfragment is not anything native to android Mar 09 16:56:53 you mean it is not possible to do what I want? Mar 09 16:57:01 theodor87 best thing to do regarding listviews, extend a BaseAdapter and watch http://www.youtube.com/watch?v=wDBM6wVEO70 first Mar 09 16:57:14 i assume you copied from http://developer.android.com/reference/android/support/v4/app/FragmentPagerAdapter.html Mar 09 16:57:25 ok i will check it Mar 09 16:57:35 listfragment is a convenience class Mar 09 16:57:47 understanding listview under the hood is really beneficial Mar 09 16:58:22 xorgate, well no it doesn't look good because its not registering i never get the registerId() heh Mar 09 16:58:26 for some reason Mar 09 16:58:48 That code has all the classes I used so yes Mar 09 17:00:48 xorgate I know how to add a custom row (specified by an xml layout) in a ListView. What I can't find how to do is add a custom row in an ArrayListFragment Mar 09 17:02:03 the fragment contains a listview Mar 09 17:05:50 xorgate to the code you linked http://developer.android.com/reference/android/support/v4/app/FragmentPagerAdapter.html can you tell me how to implement a custom row on the list? Mar 09 17:06:22 theodor87 do you understand where the listview gets its data Mar 09 17:06:33 the adapter Mar 09 17:06:53 which uses Cheeses (whatever that is) Mar 09 17:06:53 but I want to have a custom Layout Mar 09 17:07:19 well do yourself a favor, extend BaseAdapter, override getView() and in it inflate your custom layout Mar 09 17:07:37 and set an instance of it as your adapter Mar 09 17:08:21 anyone know why onRegistered(); in my GCMIntentService is not being called? (I see the broadcast in logcat) Mar 09 17:08:29 To the example which class must extent BaseAdapter? Mar 09 17:08:48 theodor87 that's not valid english, what do you mean? Mar 09 17:09:45 In the sample code that you linked which Class must extend BaseAdapter? Mar 09 17:09:58 Cheese? Mar 09 17:10:04 you make a new class, MyAdapter extends BaseAdapter Mar 09 17:10:44 you tell it 'use this array of data as content for the list' Mar 09 17:11:02 and getView() says 'this is item x in the list, what are the contents' Mar 09 17:12:57 I believe there is one problem. If I make make a new Class which extends BaseAdapter then I will not be able to use the class which extends FragmentPagerAdapter Mar 09 17:18:00 ok well i didnt properly read that page anyway, apparently the adapter supplies fragments Mar 09 17:18:28 so you have 2 kinds of adapter Mar 09 17:18:33 one for the fragments, don't change it Mar 09 17:18:36 and one for the listview Mar 09 17:19:02 i think you'd best start with a simple activity containing a listview and see how that works Mar 09 17:21:10 ok xorgate. thank you for your help Mar 09 17:23:31 anybody here knowing something bout AOSP?

Mar 09 17:26:26 err GCMIntentService ** Mar 09 17:27:59 Bear10 i had some issues with the intentservice having to be in the 'root' package Mar 09 17:28:08 or you have to somehow tell it to use another package Mar 09 17:41:21 I have a tab host with a progressBar somewhere on it. Each tab though calls an async task. How can i control that progress bar? I keep getting null pointer exceptions every time i try referencing it Mar 09 17:42:07 MajorZero Mar 09 17:42:09 onprogress Mar 09 17:42:29 MajorZero you have 1 progressbar for all activities? Mar 09 17:42:32 if so is it static? Mar 09 17:42:39 or how do you pass it on? or are you workign with fragments? Mar 09 17:44:25 im not working with fragments. I just have 1 progress bar in my tabhost activity Mar 09 17:44:46 my tabhost has a static header on top that is shown in each of my tabs Mar 09 17:44:53 thats where I have the progressBar Mar 09 17:45:01 xorgate, let me give that a shot Mar 09 17:45:17 i want to be able to show the progress bar everytime I do an async task in each of my tab activities Mar 09 17:47:42 xorgate, wow you got it! Mar 09 17:47:44 hahaha Mar 09 17:49:21 going to see if i can get it working in a diff package Mar 09 17:50:41 yeah theres some function you can call Mar 09 17:50:44 yep Mar 09 17:50:45 got it Mar 09 17:50:50 what is it? :0 Mar 09 17:50:56 i had it set but i take it it was to be honest not completely sure what changed lol Mar 09 17:51:55 aha Mar 09 17:51:56 i do know Mar 09 17:52:54 the problem was category, and service tags, the path wasn't right i guess (not sure what the difference is though) but hey it works Mar 09 18:01:51 i've finally found my problem Mar 09 18:02:11 camera.open is null because I have a front facing camera Mar 09 18:02:25 how do i tell my app to use the front camera? Mar 09 18:02:50 i tried Camera.open(1) Mar 09 18:02:55 but it didn't help Mar 09 18:03:04 what ID does the front camera get? Mar 09 18:04:05 ParameterscameraId the hardware camera to access, between 0 and getNumberOfCameras()-1 Mar 09 18:04:14 do modern phones like samsung s3 do double on fpu? Mar 09 18:05:01 calmchess Camera.open() : If the device does not have a back-facing camera, this returns null. Mar 09 18:06:49 right Mar 09 18:06:54 no back camera Mar 09 18:07:01 so how do i tell it to use the front obne Mar 09 18:07:03 one Mar 09 18:07:12 i have a kindle fire hd Mar 09 18:07:44 i tried 1 -1 and 0 Mar 09 18:07:50 but nuffin works Mar 09 18:08:06 getnumberofcameras returns 1 Mar 09 18:08:13 so I can see the cam Mar 09 18:08:18 but cant use it Mar 09 18:08:52 u ever used the front cam on a phone? Mar 09 18:09:04 I wish my thunderbolt were here Mar 09 18:09:51 idunno i'd google it Mar 09 18:12:34 does anyone know how I can have a static progress bar display on my application and allow different activities to manipulate it? Mar 09 18:15:55 i did it ! Mar 09 18:16:08 it involves a for loop and if statement Mar 09 18:16:11 what a pain Mar 09 18:16:16 but i have progress Mar 09 18:16:37 now set parameters isn't working Mar 09 18:16:47 but i'm gaining valuable knowlege Mar 09 18:17:06 anybody want me to pastebin the code for getting the front cam? Mar 09 18:19:25 If i want to backup SMS, can i savely ignore the NULL type fields like service_center, subject, reply_path_present? Mar 09 18:20:16 you can unless you want to use them Mar 09 18:20:29 parameters can always be safely null Mar 09 18:20:39 long as it doesn't cause errors Mar 09 18:20:54 u just sayng hey i not passing you data Mar 09 18:20:56 ok Mar 09 18:21:14 i dont get which kind of data could be stored in null, its null? Mar 09 18:21:26 its null by default Mar 09 18:21:37 but it could be everything? Mar 09 18:21:44 its like returning null from a function Mar 09 18:22:08 sure as long as it doesn't require it to save Mar 09 18:22:32 take path for example it will save it in default location unless you tell it to put it someplace else Mar 09 18:22:32 hm k, thx for clearing this out a little ;) Mar 09 18:22:43 usually telling it where is a good idea Mar 09 18:23:26 tell the paramter of a function to be null like (myparam = null) Mar 09 18:23:41 tells the function that the paramter can be null if you want Mar 09 18:23:58 if you don't say =null then the param must have a value Mar 09 18:25:21 and what if a column type in a pointer (getContentResolver) is null? does it mean there could still be a value in the column? Mar 09 18:26:49 sure Mar 09 18:27:21 null pointer exception means a method returned null cuz it could'nt complete the request Mar 09 18:29:58 I am not sure if you are talking about the same. i mean like here: http://pastebin.com/Tt3QPMmr for example the column person in SMS has the type NULL Mar 09 18:41:46 yeah null is valid Mar 09 18:41:59 i just put that other stuff up there as examples Mar 09 18:45:18 ok, I seem to have hit a problem Mar 09 18:46:13 facebook, account sync (photos) are not easy to get to, anyone ever done any contact picture stuff where some of the accounts pictures are sync from fb ? Mar 09 18:48:50 thx calmchess Mar 09 18:58:16 what the hell is invalid picture resolution Mar 09 18:58:33 the cam says it supports 128x96 Mar 09 18:58:37 hmmmm Mar 09 19:04:48 hei guys...anyone here using AdMob to display ads in their apps? Mar 09 19:05:33 or Leadbolt if not AdMob Mar 09 19:09:21 oh yeah Mar 09 19:09:32 got my project stubbed out and off the ground! Mar 09 19:09:43 I"ve got my android wings back! Mar 09 19:10:08 see you guys in about 10 minutes with my next problem Mar 09 19:10:09 lol Mar 09 19:19:43 hello! i get a very big response from facebook sdk, right now i get the json object like this: response.getGraphObject().getInnerJSONObject().getJSONArray("data").getJSONObject(0) Mar 09 19:20:06 can i do this with a better performance/less memory? Mar 09 19:22:11 hi Mar 09 19:22:18 i have a preference activity, how can i open it with the menu key? Mar 09 19:24:46 anbody here ever use OpenCV for andoid? Mar 09 19:24:52 i don't see how to install it Mar 09 19:25:03 maybe i just link to it Mar 09 19:25:04 dunno Mar 09 19:28:02 gru__: JsonReader does streaming rather than loading everything into memory, needs api11+ though Mar 09 19:29:53 i'm programming for api 8 Mar 09 19:31:08 figured it out Mar 09 19:31:27 in that case, maybe try the gson version instead? Mar 09 19:31:49 API is basically the same, I think - http://google-gson.googlecode.com/svn/trunk/gson/docs/javadocs/com/google/gson/stream/JsonReader.html for an overview Mar 09 19:34:08 how can i show the preferences in my android example application? Mar 09 19:34:13 when i click the menu key Mar 09 19:55:43 tm604: thanks! Mar 09 20:44:14 This is a really silly question but could someone please explain how I can do this from my device: https://plus.google.com/u/0/107708120842840792570/posts/cz5TxuoNDfG Mar 09 20:44:22 Its a nexus 7 I'm working with Mar 09 20:48:38 * capella wonders if he's the only one reading about the prenda law ass-clowns.... :p Mar 09 20:50:44 apple741, what api level is your device? Mar 09 20:51:46 my 4.1.2 cm phone doesn't support this option. my 4.2.2 aosp tablet does Mar 09 20:52:02 stephen_: Hi stephen I'm on 4.2 Mar 09 20:53:08 are you supply a number as a last arg? e.g., adb shell am display-density 200 Mar 09 20:55:04 I don't think I'm that far, I'm not sure where to type it? Mar 09 20:56:46 oh, just in a terminal Mar 09 20:57:06 so, command prompt on windows. terminal on ubuntu or mac Mar 09 20:57:41 you can see your android devices attached via usb using adb devices Mar 09 21:00:22 Ah ok, so I think I'm still missing something important, when I try that example you gave above in terminal I get this error : -bash: adb: command not found Mar 09 21:02:05 oh, do you have android sdk tools installed? Mar 09 21:03:27 btw, are you sure you want to change dpi? Mar 09 21:03:54 I think I do have them installed, I just downloaded them today and I'm able to build to my device quite easily. Sorry for all of this trouble. Mar 09 21:04:08 Yeah I wanted to see how my app would look on a smaller screen Mar 09 21:05:15 well, you could keep going down this road. i haven't changed my display density before. however, it's probably best just to make an android virtual device (emulated device) with the display size and density you want Mar 09 21:06:15 if you downloaded and installed the android sdk tools, you should either put them in your PATH environment variable or reference the full path (/~/opt/adt/sdk/platform-tools/adb, for example on ubuntu) Mar 09 21:07:18 stephen_: Ah ok thanks stephen, could you point me in the right direction regarding information on setting up an emulator? Mar 09 21:07:28 (I'm very new to android :) ) Mar 09 21:08:20
