Re: [android-developers] Re: Problem with gradle build version 0.3 and signing (signingConfigs)
2013/3/1 Jonathan S xfsuno...@gmail.com
Okay, I fixed this.
signingConfigs {
myConfig {
storeFile file(signingStoreLocation)
storePassword signingStorePassword
keyAlias signingKeyAlias
keyPassword signingKeyPassword
}
}
buildTypes {
release {
signingConfig signingConfigs.myConfig

}
Thank you, that fixes my issue.

Re: [android-developers] how to download several apps automatically from the play-store
I hate to say it, but if you just google android market crawler you'll find tons of material. Whether that works with the most recent version of Google Play I'm not sure. http://code.google.com/p/android-marketplace-crawler/ https://www.bionicspirit.com/blog/2011/12/15/crawling-the-android-marketplace-155200-apps.html etc... I'm not sure how many of those still work, but I'm guessing at least one does.

[android-developers] Is there any way of knowing the screen size before rotation occurs?
Hi, I am trying to figure out the screen size I will have in portrait and in landscape at the beginning of my app. I can get the real display size using Display.getRealSize() and then calculate the navigation bar height in case there is one. However, in devices with 600dp or less the navigation bar can have different heights (depending on orientation) and may even move to the right in landscape mode. My app would needs to know these paramters when it begins (the app is connected to a cloud server that receives these dimensions when it connects - so I really need to know these before the app starts doing things). My current solution is this: id = res.getIdentifier(navigation_bar_height, dimen, android); int navigation_bar_height = res.getDimensionPixelSize(id); Although this works, it is never a good practice to use android's internal resources. Is there any other way of knowing the dimensions of the screen in a different orientation BEFORE you rotate the device? -- -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] request.queue crashing
Hi!
I am trying an USB host connection, and so far I've managed to make
connection with a interrupt endpoint. The problem lays on trying to read
data from this endpoint. Everytime i call request.queue the application
crash. The code is as folllows:
@Override
public void run() {
// STARTS EXECUTING THE CONNECTION
ByteBuffer buffer = ByteBuffer.allocate(5);
// read data from the interrupt endpoint. For IN endpoints,
// the endpoint will attempt to read the given number of bytes
// into the specified buffer.
UsbRequest request = new UsbRequest();
request.initialize( connection, ep );
while (true){
textView6.setVisibility(View.VISIBLE);
// queue a request on the interrupt endpoint
request.queue(buffer, 5);
// requestWait() a completed USB request, or null if an error occurred
if (connection.requestWait() == request) {
byte[] data = buffer.array();
String str = new String( data);
textView6.setText( str );
} else {
Toast toast = Toast.makeText(getApplicationContext(), Request for data
failed., Toast.LENGTH_SHORT);
toast.show();

[android-developers] Re: Is there any way of knowing the screen size before rotation occurs?
If you dont want to base on pre-existing values you can just measure your existing views. This will need to happen AFTER the rotation... so your best bet is to refactor your code to work after rotations and not before (which is kind how it should be). Why is doing it before the rotation is important to you?

[android-developers] Setting up APK Expansion files for update releases
Hi, I need some clarification on using APK Expansion files. I have tested and will be releasing my Android app using APK Expansion files for the first time. My app versionCode is 61. My main expansion file is main.61.com.my.package.obb. There is no patch file. In planning ahead for my first update with expansion files, I'm a little unclear on the numbering for the expansion files and what I would load to Google Play. My next releases versionCode will be 62. There will be no changes to the main expansion file, but I need the main file. Do I use main.61.com.my.package.obb? There will be a patch file: patch.62.com.my.package.obb.

[android-developers] how to tell why Activity.onPause() is called
Hello, I would like to be able to tell if Activity.onPause() was called because the user is leaving the app, or simply because another Activity within the same app is coming up. I have a main Activity and a PreferenceActivity. The main Activity needs to handle onPause() differently depending on why it's called. If the user is leaving the app, it needs to stop helper threads, close various things like analytics session, deal with GL, save data to SD card etc. However, if onPause() is just to display prefs most of that should happen, and a bunch of other things should be done instead.

It works very well; actually better than I had expected because it runs even if other apps are running a foreground activity. Now I'm familiar with the Android Activity Lifecycle but I guess this means that Android (I'm using 2.33) can run many activities at once. Even when I'm running a very active GPS tracking application that is writing layers on a mapview, my no-display app starts does his work and sends the results out on an SMS message. The tracking app that was running never even blinked. I don't have any problem (at least not programming related), I'm just curious why this works.

Re: [android-developers] Re: two activities running at same time
A Service is a lot like an Activity w/o a UI, but the lifecycle is different: you have to override a rather different set of callbacks, for example.

Re: [android-developers] Re: two activities running at same time
You're right, and I've corrected my explanation about services in subsequent posts (with an eye to exactly this scheduling behavior!). That was misworded, but even so I think people conflate activities vs. services as having different threading semantics (they don't, things both run on the main thread). *This* is really what the OP fails to get right in his app, regardless of it being run in a service, broadcast receiver, activity. The point is that you really shouldn't be running blocking operations on a main thread.

[android-developers] Samsung S2 Support For Dynamic Layout

[android-developers] cost of view instantiation versus memory bloat
I have a widget that potentially uses many Views. In looking at the source for other view-intensive widgets (like ListView), I understand that it's a fairly computationally expensive process to instantiate Views. I see they're recycling children - creating them on demand, then caching them, and re-using them with updated properties when one is required. My concern is that in my case (with so many potential Views) that the cost of keeping references to them in memory might be worse than the cost of instantiating them. I'm tracking the total number of Views in the cache and see it reach as much as 60-70 at times. The requirement is such that I can't reduce the number of Views used. When the number is as high as I've mentioned, is caching and recycling Views still a better prospect than new instantiation on-demand? I believe that if I did not cache, the unused Views would be garbage-collected properly (there shouldn't be any references that I'm not catching).

Re: [android-developers] Re: Is there any way of knowing the screen size before rotation occurs?
It is important since the cloud server I am working with needs to know the layout I am using before I start my session.

However, in devices with 600dp or less the navigation bar can have different heights (depending on orientation) and may even move to the right in landscape mode. My app would needs to know these paramters when it begins (the app is connected to a cloud server that receives these dimensions when it connects - so I really need to know these before the app starts doing things). My current solution is this: id = res.getIdentifier(navigation_**bar_height, dimen, android); int navigation_bar_height = res.getDimensionPixelSize(id); Although this works, it is never a good practice to use android's internal resources.

[android-developers] Re: cost of view instantiation versus memory bloat
Your best bet is to just analyze your app memory and processing wise... see how long it takes you to initialize a view and how much memory they all use.. then find a proper balance between the two that makes sure your app is both responsive and without a risk of memory issues. My guess - unless initializing your views is something very complicated that takes a while (which might mean you'll need to redesign them since they might not be done the best), re-using will be the proper way to go.
