**** BEGIN LOGGING AT Mon Sep 17 02:59:59 2012 Sep 17 03:00:14 ok, then let me ask about those, as I haven't heard about them yet Sep 17 03:00:50 just serializing up into another form, but using an automated mechanism which you dont have to manually code Sep 17 03:01:06 so object->json and back Sep 17 03:01:42 I actually like that idea better so make it easier for other users to modify. Is there any major difference between how JSON and parcelable behave with the lifecycle Sep 17 03:01:57 also, a simple automated round-trip test of your value classes would catch any mismatches in code. Sep 17 03:02:27 not really, other than speed I suppose. Nothings going to be parcelable since it's designed for that Sep 17 03:02:49 also, of note, whatever you use is limited to 1MB. Sep 17 03:03:07 whether parcelable or JSON? Sep 17 03:03:20 right, except JSON is much less compact. Sep 17 03:03:30 you'd be passing it as one big string Sep 17 03:03:41 so parcelable still sounds like the way to go? Sep 17 03:04:12 and I meant a dozen fields as in one class, not total. It's really about maintenance. I dont find it that bad. Sep 17 03:04:35 write a unit test and dont worry about it Sep 17 03:06:15 mrenouf: I appreciate the help. My issue so far with Android is that I have learned a whole lot of how to do things and have used a lot of it, however I never know which is the best way to do something Sep 17 03:07:22 epsilonorion, that's pretty much been my entire experience. however things are settling down a bit. There are some good books and articles, but they dont always cover the nuts and bolts of things. Sep 17 03:08:19 mrenouf: I agree. Been working with fragments, ROSJava (in android), serialization, viewpager, Google MapView, etc all in the same app Sep 17 03:08:20 Reto Meier's Professional Android 4 for example Sep 17 03:08:30 I have reviewed that one a bit Sep 17 03:08:58 the short answer is there is rarely a "best way" that holds true for many situations Sep 17 03:09:27 serialization and persistence falls into that category Sep 17 03:09:56 part of the general topic of caching, basically Sep 17 03:10:28 how big is it, how often do you need it, how frequently does it change, how much of it can you afford to lose Sep 17 03:12:39 lol, yeah. In this situations, not too big, often, often, no Sep 17 03:47:02 I have eclipse indigo on my machine and android setup in it. Now I want to try eclipse juno. Is there anyway of configuring it for android using the configuration for eclipse Indigo? I am using kubuntu Sep 17 03:57:35 mrenouf: If you are out there, I have a quick question about the parcelable option with an ArrayList Sep 17 04:45:53 How do I save and persist an Itemized OverlayItem List for Mapview when the onPause lifecycle occurs Sep 17 05:01:39 Hello. Trying to get my first Android hello world program working. Code shows no errors, AVM is up. I don't know what to do next. Sep 17 05:03:55 AvgJoe47: unlock the AVM Sep 17 05:04:20 AVM is unlocked, seeing the desktop. Sep 17 05:04:21 it takes a long time to load the virtual device AvgJoe47 Sep 17 05:04:39 especially your first time running it AvgJoe47 Sep 17 05:05:07 I've already used the Browser app in the avm. Sep 17 05:05:34 So it's up and functional. Just don't know how to run my hello world app on the avm Sep 17 05:05:43 did you compile it Sep 17 05:06:33 Do I have to make it into an apk? Sep 17 05:06:41 no Sep 17 05:06:48 you just have to build it then run it Sep 17 05:07:09 have mainactivity.java on the screen and press f12 Sep 17 05:07:14 I right click on the project, select run as, and click android application. Sep 17 05:07:27 are you using eclipse Sep 17 05:07:37 F12 doesn't appear to do anything. Sep 17 05:07:41 I'm using Eclipse Sep 17 05:07:47 are you getting errors? Sep 17 05:07:57 It wil show in the debugger on the right bottom hand of the screen Sep 17 05:08:04 Under Markers on the bottom it says 0 errors Sep 17 05:08:39 AvgJoe47: did you add something in the code that can update logs? Sep 17 05:09:07 AvgJoe47,: Im sorry its ctrl and f11 to run the program Sep 17 05:09:10 if not, do add them, they are very helpful in debugging, and then run the project again, no need to restart the avm. Keep an eye on lgos. Sep 17 05:09:11 try that AvgJoe47 Sep 17 05:09:14 I don't know what that means. Sep 17 05:09:16 f11 + ctrl Sep 17 05:09:37 Ok, Ctrl+F11 brings up a new AVM window. Sep 17 05:10:55 see if the hello world app runs on it when it loads up Sep 17 05:11:23 It's up, but I no app is running. Sep 17 05:11:50 The console says "Performing com.example.test.MainActivity activity launch Sep 17 05:14:14 when I start a new activity, my old activity calls the onSaveInstanceState function, however it is not calling onCreate when starting back up and I cant get the savedinstance bundle to come up Sep 17 05:15:01 that means it is trying to launch at least... you have your manifest set up and an oncreate in ur default launcher class right? Sep 17 05:15:07 setcontentview to your xml? Sep 17 05:15:34 AvgJoe47: not epsilonorion Sep 17 05:16:53 I don't know what 'manifest' refers to, and the MainActivity.java has an onCreate Sep 17 05:20:16 AvgJoe47: did you just make a new android app then tried to run it? Sep 17 05:20:28 which would be a helloworld app Sep 17 05:21:07 Yes, File->New->Other->Android Application Project Sep 17 05:22:48 mrenouf: yes, I have it open in a tab for investigation tomorrow Sep 17 05:23:34 AvgJoe47: did you close the virtual device that was supposed to run the program? It can take a long while. Sep 17 05:24:29 I've left it open for up to an hour. I can install apk and runs apps, use the browser. Sep 17 05:25:26 What's the best way to grep through the android sources? Sep 17 05:25:43 I keep trying to use grepcode.com but that seems to fail. I also try and go to the github pages, but that seems to slow. Sep 17 05:25:52 Anyone have any go-to methods that are quick+easy? Sep 17 05:26:59 hwrd|work: sometimes i use ack Sep 17 05:28:19 Tracks: any ideas? Sep 17 05:28:19 g00s: hmm. I'll give it a try. Like for instance -- just now I was searching for the config_mediumAnimTime actual value. But I searched for like 2 minutes and couldn't find it. There must be an easier way. Sep 17 05:28:29 sorry my computer froze Sep 17 05:28:38 no worries. Sep 17 05:28:44 AvgJoe47,: you have no erros? Sep 17 05:28:47 errorS* Sep 17 05:29:03 AvgJoe47: I can't think of possibly what could be wrong not saying there isn't anything wrong. Sep 17 05:29:21 Are you on windows? Sep 17 05:29:36 no Sep 17 05:29:38 g00s: wow. Ack seems pretty damn nice Sep 17 05:29:57 good for quick one-off searches ;) Sep 17 05:30:22 found 500 no problem Sep 17 05:31:23 So on Mac/Linux you can create a new Android Application Project, Run As Android Application, the AVM comes up and the app comes up? Sep 17 05:32:12 You don't have to do anything inside the AVM for the app to come up? Sep 17 05:32:28 or in Eclipse? Sep 17 05:33:23 That should run it :/ sometimes i had to click the app in the app draward but thats all Sep 17 05:33:52 So the app should be in the app drawer? Sep 17 05:34:18 I should see test after Spare Parts? Sep 17 05:35:16 whatever you called it.. it will have the default icon Sep 17 05:36:26 or, should. It does in the video I've watched to get this far, but it's not working for me. Sep 17 05:38:21 "iPhone 5 preorder number leads to German adult dating hotline." Sep 17 05:38:36 lots of hipsters got dates :) Sep 17 05:40:47 g00s: Sadly. Sep 17 05:46:01 heya guys, I have a build tree for JB for my SGS2, and I was wondering how I could add a new platform manifest to it, so I can start working on porting to the n900? I don't want to sync the whole android git again, hence my question Sep 17 05:50:00 when working with fragments and your activity goes to onPause, what is called when the activity is resumed Sep 17 05:50:18 I've deleted the AVM and the Project, created both as the first 80 seconds in this video says (http://www.youtube.com/watch?v=EXM18wRW5Pk), it works in the video but is not working for me. Sep 17 05:51:43 epsilonorion: onResume() Sep 17 05:52:20 Source: http://developer.android.com/training/basics/activity-lifecycle/pausing.html Sep 17 05:53:57 Okay, so the more complicated question. I know the standard lifecycle, but besides onResume what is called. I assumed that onActivityCreated or something that would have the savedinstance (created during onSavedInstance) would be called, but I don't see anything Sep 17 05:54:08 I need to pull out a savedInstance bundle Sep 17 05:55:03 That's the limit of what I can help. I can't get the default hello world project to run in the AVM. Sep 17 05:55:03 onActivityCreated is called again, but I thought that bundle was different then onActivityCreated Sep 17 05:55:28 sorry, onStart is called Sep 17 05:56:27 Did you answer your own question? Sep 17 05:58:10 nope, still trying to figure it out Sep 17 05:58:12 thanks though Sep 17 05:59:17 epsilonorion: You on windows? Sep 17 05:59:23 linux Sep 17 05:59:44 Anyone here on windows? Sep 17 06:03:28 I am. Sep 17 06:08:33 AvgJoe47, do you get an error message? Sep 17 06:09:14 ok, to answer my own question in case anyone cares, symlinking .repo/projects between directories is the way forward Sep 17 06:16:52 Anyone have an idea as to why onActivityCreated or any other function with savedStateInstance does not get called when I resume with a fragment Sep 17 06:19:42 anyone here read "Brave NUI World" ? wondering if anything is applicable to android dev. seems like a lot of principles made their way into wp Sep 17 06:20:34 no, but would you recommend it? Sep 17 06:21:13 its one of the only books i can find that describes post-WIMP (genstural / natural) interfaces Sep 17 06:21:21 *gestural Sep 17 06:22:14 it was referenced in a book i just finished "The Mobile Frontier" which i recommend if you are are a designer / UX practitioner Sep 17 06:22:55 besides onStart and onResume, is anything else supposed to run when I return to a fragment Sep 17 06:23:21 oh, those people Sep 17 06:23:25 epsilonorion there are detailed lifecycle maps for activity and fragments on developer.android.com Sep 17 06:23:33 epsilonorion: yeah, i think everything after onCreate is called Sep 17 06:23:40 in the lifecycle graph Sep 17 06:23:51 epsilonorion: i good way to learn lifecycle timing with both activities and fragments, is to override all of them and put log statements in there. you'll probably learn some interesting things Sep 17 06:24:09 done all of the above for sampullman, goos, ron_frown Sep 17 06:24:22 which is just onactivitycreated Sep 17 06:24:41 I am just needing confirmation. I am trying to work with SavedState. Only onResume and onStart are called. onActivityCreated is not Sep 17 06:25:04 its not an activity is it? =) Sep 17 06:25:47 no, just a fragment, but onResume and onStart do not allow access to the savedStateInstance Sep 17 06:26:11 ron_frown: also, if you follow the lifecycle, it makes it seem as if it would be called Sep 17 06:27:38 why does MainActivity show in the launcher instead of the application name Sep 17 06:27:40 its called of course when the fragment is first created Sep 17 06:28:16 my main issue, if anyone can help is how do I pull back the data I save during onSaveInstanceState Sep 17 06:29:13 speakingcode: put an android:label on the activity Sep 17 06:29:30 epsilonorion: the activity is being resumed, not created. hence, not called. Sep 17 06:30:47 JakeWharton: I agree, and do follow that, which is why i was not suprised when onResume and onStart were called, however, if this is the case (which I desire), I still need to know how to grab the bundle saved during onSaveInstanceState Sep 17 06:31:03 alread ythere, JakeWharton Sep 17 06:33:15 epsilonorion: it's available in onActivityCreated, onCreate, and onCreateView if I remember correctly Sep 17 06:33:27 and if those aren't being called, then you shouldn't need access to it Sep 17 06:34:11 and onViewCreated and onInflated (just looked) Sep 17 06:34:37 JakeWharton: I do seem to though. I create a parcelable object that MapView has access to. When I press home, onSaveInstanceState is called and I am placing the object in the bundle. Sep 17 06:35:18 When I start the app up again, the onResume and onStart functions are called, but none of the items placed in the object have persisted due to none of the functions I assumed would grab it from the bundle are called Sep 17 06:35:29 this includeds any create variations Sep 17 06:37:22 onResoterInstanceState? Sep 17 06:37:32 doesnt exist for fragments Sep 17 06:37:45 *onRestoreInstanceState () Sep 17 06:38:02 JakeWharton: Actually, let me ask this question and I might be able to bypass this then. How do I get an ItemizedOverlay List created through mapview to persist Sep 17 06:38:10 are you calling setRetainInstance(true)? Sep 17 06:38:25 no Sep 17 06:38:27 I don't use Google's MapView Sep 17 06:38:32 so not sure on the latter question Sep 17 06:38:53 understood Sep 17 06:41:03 is it possible to write an app that communicates with other apps using nfc and transmits data that way? Or is nfc only useable in the default os scenarios? Sep 17 06:41:09 dang wtf is up with this Sep 17 06:41:24 why is it showing activity label on the launcher that makes no sense Sep 17 06:41:41 because you can have multiple launcher icons Sep 17 06:41:43 uhh what sort of data Sep 17 06:42:01 Mech0z: apps communicate with each other using intents. nfc is for phone to phone/tags Sep 17 06:42:06 speakingcode remove the launcher and main intent filters form the other activities in androidmanifest.xml Sep 17 06:42:55 f2prateek:so its possible (When you say phone to phone) Sep 17 06:43:27 i havent used the nfc api's, but i woudl think so Sep 17 06:43:55 i have only one icon Sep 17 06:44:07 and it shows "MainActivity" Sep 17 06:45:07 nm, i see Sep 17 06:46:29 thanks JakeWharton - O Sep 17 06:46:34 I'm an idiot* Sep 17 06:49:15 of course you can send data Sep 17 06:49:26 I think as long as nfc has been avaliable, so has the instant wifi conn stuff Sep 17 06:49:33 which is what you want to do for sending large files etc Sep 17 06:50:28 is it possible to programmatically inflate a view so that is fills the width of a GridLayout? Sep 17 06:50:40 it doesn't seem to work Sep 17 06:51:03 did you set your layout params? Sep 17 06:54:58 yeah. i guess my issue is that wrap_content doesn't fill the layout, but match_parent fill the whole screen, pushing the rest of the layouts out Sep 17 06:55:06 *fills Sep 17 06:56:25 is the only way to get 2+ layouts to "share" the whole screen in a GridLayout to dynamically calculate the desired sizes? Sep 17 07:14:36 i need to download stuff asynchronously while the user does other stuff. right now, i use an AsyncClass subtask to do the download, and then in onPostExecute i want it to pass the downloaded data to the activity or to the view. right now, i'm trying to send an intent from the AsyncTask instance out, have a BroadcastListener receive it, and have the BroadcastReceiver send it to the activity, which has been set as an instance variable Sep 17 07:14:36 of the BroadcastReceiver. all of this seems very complicated, and i don't know how to broadcast intents from AsyncTask Sep 17 07:14:45 is there a better way to do this? Sep 17 07:18:30 what? Sep 17 07:18:43 whomp_: if i'm certain the activity won't go away, i just pass the async task a pointer to it Sep 17 07:18:50 if you need 1 parameter pass in one parameter with the generics Sep 17 07:19:01 if you want more, create parameters to the constructor and instantiate it Sep 17 07:19:52 iirc asynctask already handles onPostExecute in the ui thread, so you should just be able to instantiate anonymously and access outer scope Sep 17 07:20:20 that's correct Sep 17 07:20:58 sounds like you are making it harder than it needs to be =) Sep 17 07:22:51 is there a way to make a 3x3 grid of buttons in a gridview all the same size, while filling the screen width? Sep 17 07:23:34 for some reason the right/bottom button is ~2/3 of the size. Sep 17 07:24:55 i read that GridLayout 'prefers' right/bottom views, is there a way around this? Sep 17 07:25:05 err.. read the previous GridView as GridLayout Sep 17 07:25:10 hi. what xml entry can set the progress bar color? Sep 17 07:25:20 or which one? Sep 17 07:25:34 There's no "color" attribute Sep 17 07:25:42 You have to change the drawable used for the progress indicator Sep 17 07:26:16 mmm Sep 17 07:26:19 let me see Sep 17 07:29:39 hello everybody Sep 17 07:29:57 i am getting this strange behaviour for one samsung tablet GT-p7300 Sep 17 07:30:02 i am getting outofmemoryerror for one device since the dalvikkvm heap size gets more than 50mb and doesn't get reduced Sep 17 07:30:17 memory leak Sep 17 07:30:43 while on the other 2 tablets i don't get this issue since i can see the increasing and decreasing size of the kvm heap Sep 17 07:30:56 sampullman: hi Sep 17 07:31:06 sampullman: why its happening for a certain device Sep 17 07:31:08 ? Sep 17 07:31:39 There's a heap limit Sep 17 07:31:41 sampullman: for other device i can see the dealloating of memory Sep 17 07:31:44 could be a bug, i guess Sep 17 07:31:45 Can depend on device and platform version Sep 17 07:31:55 Use less memory Sep 17 07:32:22 If a number of objects needed to be shared across many activities in an app, what would you people suggest to use? A singleton class or extending the application object? (See, I cannot share these objects since they are neither serializable nor parcelable) Sep 17 07:32:44 napster: why not extend the Application class? Sep 17 07:33:18 i think both would be fine, though Sep 17 07:33:24 sampullman: hmm, I would have but, I need to fiddle with these objects when broadcasts are being received. Sep 17 07:34:05 Brodcast receiver class doesn't have getApplication() method as I understand. Sep 17 07:34:18 napster I wouldnt do it if there was anyway to avoid it Sep 17 07:34:29 sampullman, i ended up doing that. i was just afraid that the asynctask class would lock its instance variables while it's in use Sep 17 07:35:02 too much shit going on with androids activity manager and lifecycles and shit to go tossing a ton of crap in a singleton somewhere Sep 17 07:35:20 ron_frown: what's wrong with extending Application? Sep 17 07:35:24 ron_frown: sampullman : The base thing is I cannot bundle these obejcts as extras since they are not parcelable or serializable Sep 17 07:35:41 sampullman: nothing but broadcast receivers! :) Sep 17 07:35:48 why isnt it serializable Sep 17 07:36:32 ron_frown: Because they comes from a closed source library Sep 17 07:36:40 sampullman - nothing... but I just wouldnt go loading it up with a ton of data Sep 17 07:37:00 kepe in mind the scope of application, android cant/wont do any cleanup after the activity goes bye bye Sep 17 07:37:11 right Sep 17 07:37:18 data may be floating around Sep 17 07:37:33 So, what do you guys think about Singletons? Sep 17 07:37:35 but as for the broadcast receiver thing, doesn't onReceive get a context? Sep 17 07:38:15 sunny_slls: is that GT-p7300 a honeycomb device ? Sep 17 07:38:17 sampullman: Yes it does but not application context as I see, but I can't figure it out very clearly from the docs either Sep 17 07:38:57 may be some android gurus can clear it for us. :) Sep 17 07:39:18 g00s: nope Sep 17 07:39:23 g00s: sorry yes Sep 17 07:39:33 g00s: 3.1 version Sep 17 07:40:03 does you mug manifest on ics or above ? Sep 17 07:40:08 *bug :) Sep 17 07:40:52 g00s: sorry i didn't get you Sep 17 07:41:19 sunny_slls: what are the other 2 tablets ? Sep 17 07:41:25 (android versions) Sep 17 07:41:49 Or the question can be rephrased as "Is it possible to refer the application context from a broadcast receiver?, is yes how?" Sep 17 07:42:24 g00s: the other 2 are version 3.1 and version 4.0.4 Sep 17 07:42:47 interesting, so the other 3.1 device does not show the problem Sep 17 07:43:40 g00s: the other tablet with OS version 3.1 has 32GB internal memory and 1 GB ram Sep 17 07:43:57 Most HC devoces have a 48mb heap Sep 17 07:44:05 ron_frown: sampullman : Or I will need to experiment if I can pass the activity context and then call getApplicationContext() on it. That should theoretically work, isn't it? Sep 17 07:44:31 napster: i'd imagine you can just cast the context in onReceive to Activity, then call getApplication Sep 17 07:44:32 mmmmeh Sep 17 07:44:36 I'll just back out Sep 17 07:44:41 I dont want to contribute to badness Sep 17 07:44:47 hahaha Sep 17 07:44:57 sampullman: Thats what exactly I was thinking, and I typed faster than you ;) Sep 17 07:45:22 ron_frown: err...! Why it is badness?? Sep 17 07:45:27 ron_frown is right, though..that's not so good Sep 17 07:45:27 g00s: SimonVT actually i extracted build.prop file and got these configuration data Sep 17 07:45:29 dalvik.vm.heapstartsize=5m dalvik.vm.heapgrowthlimit=64m dalvik.vm.heapsize=288m Sep 17 07:45:59 better to make the objects parcelable Sep 17 07:46:00 sampullman: ron_frown But you have moral obligation to say, 'Why?' :D Sep 17 07:46:20 because I think the solution you are shooting for is probalby not the way to solve this problem correctly Sep 17 07:46:31 I do think its fine to implement an application class Sep 17 07:46:49 but understandling lifecycles and scopes is important Sep 17 07:47:03 ron_frown: hmm, agreed Sep 17 07:47:06 you'll be preventing android from cleaning up resources Sep 17 07:47:23 Still, better memory management Sep 17 07:47:24 I mean when your app is killed, your application shit will go waway Sep 17 07:47:47 ron_frown: And how will be the case if I choose to use a Singleton? Sep 17 07:48:18 SimonVT: You think extending the application implies better memory management? Sep 17 07:48:22 depending on singleton route, you may be building static initializer, which will be lifetime of the app, a variable on the application Sep 17 07:48:29 No, this was for sunny_slls Sep 17 07:48:35 oh sorry Sep 17 07:48:37 variable on application = memory consumed lifetime of tha pp Sep 17 07:48:40 If he is getting outofmemoryexceptions, he needs better memory management Sep 17 07:48:49 sure you can nullify etc Sep 17 07:49:07 but ideally you keep references to your data as short as you can get away with them Sep 17 07:49:38 hmm, ok. So what do you suggest? Sep 17 07:50:55 get your objects serializable Sep 17 07:51:00 which is easy enough to do Sep 17 07:51:04 or make them parcelable Sep 17 07:51:16 whats the nature of the data Sep 17 07:51:45 shit very worst case scenario, you should be able to json serialize that shit and deserialize Sep 17 07:51:49 I mean thats overhead you shouldnt need Sep 17 07:51:55 ron_frown: It is practically hard to make them extend. As you may know I'm using the Parse library. And these are parseObjects Sep 17 07:52:08 I dont know what parse is Sep 17 07:52:15 this is worst case, trust me Sep 17 07:52:30 just use gson to serialize deserialize to json Sep 17 07:52:38 at least once the flow is complete, the data is gone Sep 17 07:52:51 but I would choose parcelable or something before that Sep 17 07:53:06 ok Sep 17 07:53:21 dont be afraid to use application for stuff Sep 17 07:53:37 and hell if what you are sending across is tiny, I suppose it wouldnt be problematic Sep 17 07:53:54 but its kinda round about Sep 17 07:54:00 ok, the size of the data does matter Sep 17 07:54:54 ok, let me give it a try. Thanks a lot ron_frown & sampullman Sep 17 07:55:25 napster I didnt mean to sound harsh, but I'm trying to help save you from some of the mistakes I made when I was new Sep 17 07:55:47 ron_frown: no problem mat, I understand e :) Sep 17 07:55:53 theres a lot of shit that happens behind the scenes and it seems like any time I'd try to come up with workarounds they'd frequently bite me in the ass in the end Sep 17 07:56:09 hmm Sep 17 08:17:43 hello all, I create a surface view that just draws a bitmap continuously. Due to the performance issue, I set the bitmap and rescale the bitmap such that the size is fit the size of the Surfaceview. However, when I call getWidth and getHeight in SurfaceView, it returns zeros so that I cannot know the size of the view. How can I tackle this problem? Sep 17 08:18:12 getMeasuredWidth? Sep 17 08:20:07 alex_PP: what is the difference between measured width and width? Sep 17 08:23:22 it doesn't help Sep 17 08:25:24 when are you calling it? Sep 17 08:25:49 getWidth will return 0 until it's parent is measured Sep 17 08:25:53 its* Sep 17 08:26:50 i.e. when you call getWidth or getMeasuredWidth in onCreate Sep 17 08:28:33 surface views have holders. holders have the callback, which fires when it's sized Sep 17 08:28:37 I think that is the way Sep 17 08:30:05 you can override onSizeChanged and do it there Sep 17 08:30:56 Hi guys. Does anyone know how to fix this fucking INSTALL_FAILED_INSUFFICIENT_STORAGE issue with adb? I have sufficient storage space. I even put the android:installLocation="preferExternal" in the manifest. Each time I reboot, try again, and that works. I'm not on the emulator neither. Sep 17 08:31:01 It happens randomly. Sep 17 08:31:40 pcboy_: maybe there's a clue in logcat about what more specifically went wrong Sep 17 08:31:54 hello, I'm trying to use "adb pull" to get the .apk of an app I developed and put on my tablet, but it's not under /system directory (I guess it's for pre-installed apps only), but I can't find my app anywhere ... Sep 17 08:32:12 sampullman: I think it is called after onCreate Sep 17 08:32:41 sampullman: I have a button that open a Image.Pick intent to allow user to pick an image. Sep 17 08:32:43 yeah, do you absolutely need it in oncreate? Sep 17 08:33:20 sampullman: I don't call it onCreate Sep 17 08:33:25 oh Sep 17 08:33:43 I set the bitmap in onActivityResult Sep 17 08:33:56 if you can see the view, getMeasuredWidth should work Sep 17 08:33:57 that means, when the user selected an image Sep 17 08:34:51 I don't know, this is ok for fast device. For slow device, the screen is black, and then exception throw Sep 17 08:35:23 well, what does the stacktrace say? Sep 17 08:35:52 the stack trace is about Bitmap.createBitmap with zero size Sep 17 08:36:01 the size I input is the surface view size Sep 17 08:36:16 that's why I said the getWidth and getHeight return zero to me Sep 17 08:36:50 and you have tried getMeasuredWidth/height? Sep 17 08:37:12 yep, the same result Sep 17 08:37:56 alankila: Good call. I have a Failed to unmount container error. Device or resource busy. It can't unmount my app to replace it. Now I'm just wondering why. Sep 17 08:38:41 well, if the view isn't rendered at that point, they would return 0. otherwise, i don't know Sep 17 08:41:25 hello, I'm trying to use "adb pull" to get the .apk of an app I developed and put on my tablet, but it's not under /system directory (I guess it's for pre-installed apps only), but I can't find my app anywhere ... Sep 17 08:41:32 Morning All! Sep 17 08:42:04 Morning! Sep 17 08:42:09 getWidth wont return the width until the layout pass has executed (View.onLayout is called).. getMeasuredWidth wont return the width until the measure pass has executed (View.onMeasure is called) Sep 17 08:46:58 SimonVT: umm, but I still don't know why it returns 0 when I can getWidth in the view when onActivityResult Sep 17 08:49:16 Because your views have already been measured and laid out before you start the new activity, maybe Sep 17 08:50:59 then it should not be zero I think if the views have already been measured. Sep 17 08:52:44 I don't know what you're doing. Look, unless your view has been measured and laid out, getWidth/Height will return 0 Sep 17 08:54:34 Override the appropriate methods if you need to know when that happens Sep 17 08:56:09 SimonVT: ok, let me explain. I start an activity with a surface view which is invisible first. a button to ask user to select image. After selected image, onActivityResult is called and I call getWidth in the surface view. It returns zero for the width of the surfaceview. Sep 17 08:58:37 If it's invisible (View.GONE or View.INVISIBLE), then it's not being laid out Sep 17 08:58:45 If it's View.GONE, then it's not being measured Sep 17 09:00:08 If it's not being measured, getMeasuredWidth will return 0.. If it's not being laid out, getWidth will return 0 Sep 17 09:00:58 ok, let me try if this is visible Sep 17 09:04:28 the same problem…. : ( Sep 17 09:06:44 hello. Have anyone had any succes connecting an android 4.0 device to a bluetooth low energy peripheral? Sep 17 09:10:18 Jesper_: from what i can tell, android does not support BLE although some phones have BLE capable chipsets Sep 17 09:11:10 but iOS and WP8 do, fyi Sep 17 09:14:44 why is lint showing me an error message I fixed 5 days ago whenever I start eclipse? It's easy enough to get rid of it, but it's still annoying. Sep 17 09:16:07 g00s: yeah that was my conclusion as well. I have 2 test phones here with bluetooth 4.0 which should support BLE, but since the connection protocol is different from regular bluetooth, i cant use them :P Sep 17 09:16:59 http://imsresearch.com/press-release/Is_the_Google_Platform_Delaying_the_Bluetooth_Smart_Train Sep 17 09:18:19 i think its a big fuck up on google's part. two areas of mobile which are emerging are the shifting boundaries between phone / environment, and phone / human. sensors, which would be low power (Zigbee, BLE, etc) are not supported. this means android basically is incapable of participating in these trends at the moment Sep 17 09:21:39 g00s: just read the article, you're right. this is a fatal thorn in my eye :P my boss is kinda disappointed i havent gotten it to work yet, but that should shed some light on why at least :P Sep 17 09:26:14 ive got a list on my actionbar (abs), and it works etc, but itseems a little odd, when i first go into the screen the top item of the list is automatically called in opnItemSelected, and if i hit it again it wont call, only seems to call onItemSelected when i touch another option and go back Sep 17 09:26:16 Jesper_: yeah, hopefully your boss understands. its been a thorn in my eye also :P enough to cause me to switch to another platform Sep 17 09:26:34 Gaaaaaaaaaz Sep 17 09:26:39 is your game done yet :P Sep 17 09:26:41 :) Sep 17 09:26:44 did you get paid :P Sep 17 09:26:44 no :( Sep 17 09:26:55 g00s: yeah unfortunately I can't switch platform as that is not my decision to make Sep 17 09:26:55 still waiting for pay from client, working for new one now Sep 17 09:27:16 goos: found this though; http://code.google.com/p/broadcom-ble/downloads/list Sep 17 09:27:17 game hasnt done much but im demoing it at indie game movie premier in taiwan :) Sep 17 09:27:19 this week Sep 17 09:27:43 Jesper_: cool, thanks Sep 17 09:27:53 cant understand these lists on actionbars, theyre more like modes than list items Sep 17 09:28:11 id expect if u hit same one that is already selected it would simply call onItemSelected again Sep 17 09:30:13 Why are you assuming behavior when you can just read how it works Sep 17 09:30:23 Jesper_: if you are around sometime i'd like to ping you to see if this worked. Sep 17 09:30:26 well im not sure this is documented Sep 17 09:30:31 wher ewould i read it Sep 17 09:30:37 Javadocs? Sep 17 09:31:38 seems pointless that this feature behaves like this to me Sep 17 09:33:45 g00s: just found out that the HTC one S im working with now uses a Qualcomm, not a broadcomm bluetooth modem. "The HTC One X and One S use a Qualcomm Bluetooth chip, not Broadcom. Therefore the Broadcom SDK would not be expected to work" Sep 17 09:34:32 yeah, i would think the kernel and bluez need to support this, as well as the Bluetooth service in the framework Sep 17 09:54:14 hey guys when should we use the subclass the Application class and use it? Becasue we can do that via singleton class also Sep 17 09:56:40 but that singleton wouldn't be a context Sep 17 09:57:17 I use the application context as singleton and for caching data Sep 17 10:00:57 Is there a linux command which will tell you the manufacturer and model of an internal hard drive? Sep 17 10:02:42 Ankhwatcher, hdparm Sep 17 10:03:04 or smartctl Sep 17 10:03:13 EPG: format hdparm /dev/sdd? Sep 17 10:03:32 mephju: so that's means that i can use that application context anywhere right. Sep 17 10:03:45 hdparm -I /dev/sda Sep 17 10:03:52 mephju: what if i am not using that application context ? Sep 17 10:04:05 anywhere Sep 17 10:04:06 EPG, Leeds thanks Sep 17 10:04:39 <[deXter]> Ankhwatcher, Also, hwinfo --disk Sep 17 10:07:21 hey if i am calling one activity from another activity should i use this global context or should i pass the "this" (activity context)? Sep 17 10:07:56 calling one? you mean startActivity? Sep 17 10:12:43 sunny_slls, I always use the kind of context which is closest to the code I am writing Sep 17 10:13:22 also it's important to start activities always from an activity context... Sep 17 10:13:38 at least without setting flags in ur intent Sep 17 10:14:30 I got a question myself... 9 patch graphics don't work properly on my device but do so in the layout editor...anyone else experiencing this? Sep 17 10:14:49 mephju: but then we can always get global context from Context.getApplicationContext() Sep 17 10:15:08 mephju: why to subclass application for that ? Sep 17 10:15:55 to get ur own loging in there... Sep 17 10:16:01 logic Sep 17 10:16:07 not loging ;) Sep 17 10:17:14 mephju: i am not clear with this. can you please explain more Sep 17 10:18:05 i can have a singleton class for caching data Sep 17 10:18:08 right Sep 17 10:18:12 for example if you want to store some objects in the application context you have to subclass it Sep 17 10:18:57
