[android-developers] Unit testing methods containing Handler

@Override
public void run() {
super.run();
h.post(new Runnable() {

I'm using AndroidTestCase class, and my test looks like this :
@UiThreadTest
public void testOnStartIsCalled() {
mMyObject.start();
assertTrue(mMyObject.isRunning());
}
But the Runnable posted in the Handler has never ran.
How could I test that the callback has been called ?

This is not an android specific question. You just need to learn JNI,

Re: [android-developers] Re: Custom DialogPreference and PreferenceManager.setDefaultValues issue
Hi Ibendlin,
Thanks for helping me :)
I don't think the problem is in SeekBarPreference.onSetInitialValue()
function itself as it is never called (I have put a log in it to check).
There is certainly an issue somewhere in my implementation; when
setDefaultValues is called, only SeekBarPreference constructor is called.
I was suspecting the xml, but I don't see any problem in it
(android:defaultValue is set and android:persistent as well):
com.tlegras.tools.SeekBarPreference
android:key=preferences_epg_daytostore
android:title=@string/preferences_epg_daytostore_title
android:summary=@string/preferences_epg_daytostore_summary
android:dialogMessage=Nombre de journées à télécharger.
Attention, plus ce nombre est élevé, plus le chargement sera long et moins
l'application sera réactive.
android:text= jour(s)
android:defaultValue=4
android:max=5
android:persistent=true
/
2011/10/11 lbendlin l...@bendlin.us
it took me a few weeks to get that right. here's my example for a boolean
value. And yes, .setDefaultValues is actually working, despite what you may
think :-/
@Override
protected void onSetInitialValue(boolean restoreValue, Object
defaultValue) {
boolean temp = restoreValue ? getPersistedBoolean(false) :
defaultValue.toString().equals(true) ? true : false;
if (!restoreValue)
persistBoolean(temp);
this.oldValue = temp;

Thanks, it looks better when I added an alpha channel to the textures. But I don't see that glBlendFunc(GL_SRC_ALPHA, GL_ONE) made any difference. There are still black square quads, but less than before. I tried to remove the gl.glColor4f calls, but that made the black square quads much more visible. This is how it looks like now, with gl.glColor4f(1f, 1f, 1f, 0.4f); http://www.mobile-visuals.com/color4f04.png with gl.glColor4f(1f, 1f, 1f, 0.8f); http://www.mobile-visuals.com/color4f08.png with no with gl.glColor4f calls: http://www.mobile-visuals.com/noColor4f.png This shows that with higher alpha value in glColor4f, the more black square quads.

[android-developers] Re: Scenario where initLoader() does not call onLoadFinished()
Indeed, the loader manager destroy() method is called and the field mDestroyed is set to true. After this, the loader manager is not functional anymore. In onLoadComplete() it exits if mDestroyed is set to true. So i guess the problem is that the loader manager for that fragment is destroyed but our fragment is still alive. I would venture to say that this is a bug. It would be helpful if we find a workaround. I have a big app with a lot of fragments using loaders.

[android-developers] Re: SQLite concurrency
I just made the Database objects singletons as suggested by Mark. What a fantastic idea -- this solved so many of my problems and complexity in my app. My app deals with a user configurable number of databases (like files in a desktop app) and switching between them was a pain in the b*tt. This solved all my issues related to screen rotation, services accessing the database, etc. Highly recommended for anybody. The only problem is that the datrabase is never closed. But this is more of a pedentic observation as there seems to be no real side effects. I do wish there were a onDestory() on the Application object so I could close the databases before Android terminates my app, but alas, there isn't. Of course, creating a Content Provider is deseriable, but non- practicle. My app deals with very complex queries and since there is currently no reason to expose my data to the outside world, a Content Provider is not only very complicated to create, but it's also unneccessary.

[android-developers] It is possible to rotate a object from his own coordinates and not from the plane coordinates?
I am following the OpenGL es rotation examples from google to rotate a simple Square (not a cube) on my Android App, for example this code: gl.glRotatef(xrot, 1.0f, 0.0f, 0.0f); //X gl.glRotatef(yrot, 0.0f, 1.0f, 0.0f); //Y gl.glRotatef(zrot, 0.0f, 0.0f, 1.0f); //Z It works fine if you only rotate to one axis. But if you rotate to one axis, and after that, you rotate to other axis, the rotation is not fair.

If it does then specifying GL_SRC_ALPHA would apply the alpha once more causing transparent pixels to darken. You'd need GL_ONE in that case. gl.glTexEnvf(GL10.GL_TEXTURE_ENV, GL10.GL_TEXTURE_ENV_MODE, GL10.GL_MODULATE); I believe this is the default so you could just as well leave it out. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] How to store cookies in an application for future use?
Hi All, In my application, I get all the cookies from the post requests with the HttClient.getCookieStore method. I want to save these cookies so the next time the app is started, the user don't have to log in. I don't know how to save the cookies in an application. Because in the shared preferences, only primitive types (strings, integers, boolean values) can be stored. If I store the cookie value in the form of a string. I don't know how to set it to HttClient.setCookieStore(CookieStore); when the aplication starts again Please help me.

If you're really paranoid about it, you might rig up some sort of inactivity timer that closes the database, and organize your singleton to lazy-open the database if needed. This isn't a guarantee that it'll get closed, though, as Android could terminate the process first. Having multiple SQLiteDatabase objects is fine if (and only if) you're only using them from one thread at a time via your own synchronization.

Re: [android-developers] HorizontalListView inside a VerticalListView
My guess is that the reason you're seeing that effect is that your vertical list view comes before the horizontal one in the touch event sink chain. I think that once a touch event handler returns true no further processing on that event happens. Try making your primary view horizontal, and your secondary view vertical and see if that helps. Failing that, you'll probably have to handle the touch events yourself.

[android-developers] Re: OpenGL lockups in 2.2
Nope, 'fraid not. That code seems if anything to makes things a little worse for me = intermittent screen glitches, with rectangular areas garbled, and the less frequesnt hangup for a second or so, with the even less frequent reboot. I am using Samsung Galaxy S, 2.3.3, so clearly not restricted to HTC. All hangs seem to be locking problems in SharedBufferStack. glFlush calls have no effect on my problem. Switching from glDrawArrays to VBOs and glDrawElements had no effect. This bug is SO bad and i have spent SO long on it now that I am pretty much at the stage of junking many months of work and not publishing the openGL version of my app. This comes on top of unacknowledged problems in java 2d drawing routines, the ridiculous DirectBuffer problem in 3.0+ where it allocates 4* as much memory as you ask for.

[android-developers] Move vertical Seekbar thumb to the progress drawable height?
I have vertical seekbar.
In the class which extends Seekbar I have on touch listener
@Override
public boolean onTouchEvent(MotionEvent event) {
if (!isEnabled()) {
return false;
}
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
case MotionEvent.ACTION_MOVE:
case MotionEvent.ACTION_UP:
setProgress(getMax() - (int) (getMax() *
event.getY() / getHeight()));
onSizeChanged(getWidth(), getHeight() , 0, 0);
break;
case MotionEvent.ACTION_CANCEL:
break;
}
return true;
}
When I setProgress(value) expected output is the progress bar to
change, in my case only yellow surface moves to regular value but the
thumb does not.
I tried to make it move after setting progress to
setProgress(getMax() - (int) (getMax() * progressDrawableHeight /
getHeight()));
onSizeChanged(getWidth(), getHeight() , 0, 0);
which logically means that the thumb should be moved to progress
drawable height (the edge of the yellow surface)
Any ideas?

[android-developers] 1/3 sounds is distorted when played
Hi, I am making an update to my game. I am adding an additional sound (a voice saying Game Over) to the game. There are two other sounds in the game. When I play the game over sound it is very distorted and lasts much longer than it should. The other two sounds play perfectly. I edited the game over sound in Audacity.

The code I am using to play it is: mSoundPool.play(mGameOverSound, 0.5f, 0.5f, 0, 0, 1.0f); The sound has been loaded earlier and the sound pool has been prepared properly. The sound should play saying only Game Over. Instead it sounds like G-a-a-a-a-a-m-m-m-m-m-e-e-e-e-e- O-v-v-v-v-v-v-v-e-e-e-e-e. Any idea why only this sound distorts and how to fix it?

[android-developers] Package Browser: what does Restart button do?
I was playing around with the Package Browser on the Emulator while my app was paused. I located my app's package and noticed the Restart button at the top of the page. I clicked on this button and when I went back to my app it was on the same activity I had paused, but the display was a bit screwed up. What does this restart button do in terms of app and activity life cycles? Does it do something that the OS might do? Does the screwed up screen mean that I am not persisting my activity state properly?

[android-developers] display images in galleryview from sqlite database
Hi I have a sqlite database that has over 2000 low res thumbnails of pictures. The database itself is over 100MB in size.

I don't mind if these images are lazy loaded on to the gallery view in the background. I read somewhere that I will have to use an ImageAdapter to bind the images to the UI element dynamically.

Re: [android-developers] Re: OpenGL lockups in 2.2
It's insane to throw away months of work. Are you seeing this behavior in other 2 or 3d games running on that device? If so, it's probably a device fault that you simply can't get around, and should just be ignored. There are other devices in the world that, in theory, it should work on. In your market publish, just mention that you had problems with that device and that it's not recommended to be run there, then move on. If you aren't seeing the behavior elsewhere, then what you have is an application problem. Have you considered that plugging and unplugging the USB cable is introducing thread locking that is absent in your code? When you connect the USB cable, if you have development enabled, you instantly start reading out logging info, which may have locking in there that's fixing some problem you have.

[android-developers] Re: HTC and LG haven't implemented Android in the right way
I see, now I understand the color4f method. I can't sort the transparent sprites back-to-front,because they are all in one vertex array. It would be much slower if I had one vertex array for each quad, because it would be so many drawArray calls. I will only use one layer of quads from now on. But the particles in the animation are morphed, so one particle will sometimes be placed above another. Do you mean that this will always result in black quads?

By specifying (1,1,1, 1) you leave the hue alone but add 0.4f or 0.8f transparency. Smaller alpha means dull because whatever you draw becomes almost transparent.

[android-developers] Service to Activity communication with Broadcast Reciever every 1 sec . Is this right approach?
I'm creating media player application that will run on service and all
its action (all intent actions stated in the manifest file of course)
What I did is, I created Runnable in my service that will
sendBroadcast whenever I do handler.postDelayed(myRunnable, 1000);
private Runnable updateActivity = new Runnable(){
@Override
public void run() {
if(mediaPlayer!=null)
{
Intent toActivity = new
Intent(com.share.play.SharePlayService);
toActivity.putExtra(position, position);
//32bit
toActivity.putExtra(id,
mediaPlayer.getAudioSessionId()); //
32bit
toActivity.putExtra(progress,mediaPlayer.getCurrentPosition()); //
32bit
toActivity.putExtra(duration,
mediaPlayer.getDuration()); //
32bit
toActivity.putExtra(bands, totalbands); // 5
x 32bit
toActivity.putExtra(loop, mpLoop); // 1bit
toActivity.putExtra(shuffle, mpShuffle);
//1bit
MyPlayService.this.sendBroadcast(toActivity);
handler.postDelayed(updateActivity, 1000); //
post again and
again every 1 sec
}
}};
And in my Activity I have receiver that will take the duration, and of
course the currentPosition() of the playing.
BroadcastReceiver ServiceReciever = new BroadcastReceiver(){
@Override
public void onReceive(Context arg0, Intent arg1) {
Bundle b = arg1.getExtras();
if(b!=null)
{
seekbar.setMax(b.getInt(duration));
seekbar.setProgress(b.getInt(progress));
position=b.getInt(position);
sessionId = b.getInt(id);
if(b.getInt(position)(visual.size()-1))
//Changing album
art whenever the current playing position is different from the
previous
{
position-=1;
}
else{
if(position -1 visual.size()0
!visual.isEmpty())
{
playingArtist.setText(visual.get(b.getInt(position)));
Drawable drawable = null;
try {
drawable = getArtwork();
//drawable =
drawable.getCurrent().
} catch (FileNotFoundException
e) {
// TODO Auto-generated
catch block
e.printStackTrace();
} catch
(IllegalArgumentException e) {
// TODO Auto-generated
catch block
e.printStackTrace();
}
art.setImageDrawable(drawable);
}
}
userLoop = b.getBoolean(loop);
userShuffle = b.getBoolean(shuffle);
int Minutes = (b.getInt(progress) % (1000*60*60)) /
(1000*60);
int Seconds = ((b.getInt(progress) % (1000*60*60)) %
(1000*60)) / 1000;
int Minutes2= (b.getInt(duration) % (1000*60*60)) /
(1000*60);
int seconds2 = ((b.getInt(duration) % (1000*60*60)) %
(1000*60)) / 1000;
timeline.setText(Integer.toString(Minutes) + :+
Seconds
+/+ Minutes2 +:+ seconds2); //updates the time line.
}
}
};
More over, I unregister and register the receiver regularly whenever
the activity is visible to the user or not.
1. Is there are any side-effect of this approach?
2. Is this reasonable? Does the message queue get starved?
3. Is there any rather better approach than this one? Point me
some...

The other activity can add items to the list but when a new item is added the data service needs to fetch data for it. The task to fetch data is in my main activity because it is bound to the service already. i want the main activity to observe the list so that when the other activity adds an item to the list it can run the async task to fetch data for that item. Is this the correct way to do this? If So how do i get my main activity to observe my singleton list that extends Observable? Any help would be great.

I can't sort the transparent sprites back-to-front,because they are all in one vertex array. It would be much slower if I had one vertex array for each quad, because it would be so many drawArray calls. Think about your problem from the depth sorting perspective. Again, I don't know what exactly you are doing but your geometry looks quite regular to me - perhaps the depth sorting, once established, never changes? If you're drawing everything in a single glDrawArrays() call then all of your quads share the same transformation (the same values you pass to glTranslate()/glRotate()/glScale()). If that's the case your geometry is likely pre-transformed (you transform vertices of each quad before putting them into the array) - could you sort the quads as you transform them? Try to take advantage of any problem-specific knowledge you have (and I don't). In my experience it's rather unlikely that you're unable to do the required depth sorting. I will only use one layer of quads from now on. But the particles in the animation are morphed, so one particle will sometimes be placed above another. Do you mean that this will always result in black quads? Unfortunately yes. When using translucency with depth buffering I don't know of any other solution, in general. To understand this consider you draw a partially transparent quad, just like one of yours. Its transparent pixels will not change the frame buffer since they are transparent - the corresponding frame buffer pixels will stay at your clear colour. However, the quad also writes into the depth buffer. Now, consider another quad comes that (partially) overlaps with the first one and should be visible where the first quad had transparent parts. Also consider that this second quad can be further away from the camera which can well happen since your quads are *not* back-to-front sorted. The second quad will be prevented by depth test from writing to any pixels touched by the first quad. This means your clear colour remains where the first sprite was transparent/translucent. Hence your black rectangle - a quad close to camera comes first and blocks other quads further away from the camera from writing over it. I'm afraid you will have to figure out how to depth-sort your geometry properly. As I said before, it shouldn't be *that* tough. ;-) I will only use star1.png for testing,since you said that image was correct. I used this guide to add the alpha channel: http://fabiovisentin.com/tutorial/gimp_transparent_image/gimp_how_to_make_transparent_image.asp That is a fine tutorial, however you will notice the example image has (perhaps apart from some anti-aliasing) sharp edges. The process they describe there is appropriate for that sort of images. However, your stuff is supposed to smoothly blend into its surroundings, with no defined edge, pretty much. The process from the tutorial is not well suited for this kind of image. Consider getting rid of the black component in your art for instance by loading it into Gimp, then going to Colours-Colour to Alpha... and setting the colour to black. I checked and even star1.png seems to have more black in it than would look right ... Only you know what you're trying to achieve so this might or might not be an appropriate fix. To me, your art fixed like this looks about right and ready for some serious blending. ;-) -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: OpenGL lockups in 2.2
Difficulties with one device I have no way of knowing how many makes/models of device this problem is on. I know that it happens all the time on my Samsung Galaxy (I9000). Others report exactly the same thing as being a feature of a number of HTC devices - these two make up a major part of the market I believe. I think I may well have two faults - one is the standard eglSwapBuffers hang, which none of the suggested fixes have had any effect on -square textures, different GLSurfaceView, wait, flush, finish etc. The second one, which I think might be related, is my intermittent framebuffer corruption, I am willing to accept this may be my fault in some way I have been unable to pinpoint. http://www.fordartworks.co.uk/dodgyS.png - the ractilinear dodgy area just above the left and right arrow buttons. smacks of throwing the baby out... At the moment, I am just hugely frustrated by the long list of problems I have faced with Android - halts on writing to SD card, gradients that don't work at one particular angle and so on. I have been a software designer and developer for over 25 years - parallel architecture research, trading room systems, real time etc (assembler, Fortran, Prolog, Occam, C, C++, Java) and I have never been so frustrated by any system - there has always been a different way of doing things, getting round problems. With this /these? OpenGL problem(s) it appears to be a black box. Without a genuine understanding of what is wrong, any fix is pure conjecture. should just be ignored I am extremely reluctant to put out an App that looks flakey or, much worse, shuts down people's phones. Ignoring a problem that I can't get round is not a viable solution I feel. plugging and unplugging the USB cable The USB cable stuff was a problem I had with very jerky OpenGL performance when the rendering load was heavy - this was caused by the CPU clock reducing when the GPU was active, I believe. seeing the behavior elsewhere I haven't experienced this problem with other programs on this phone. (I have not detected the problem on my Asus Transformer either, but I have tested that far less. It will also have very different performance characteristics.) I don't play games, 2D or 3D. Many of the openGL demonstrators, testers or benchmarkers don't stress the system sufficiently - i can get 50 or 60 fps. The problem is very timing dependent- i have one picture definition for my App that fails vaguely regularly - i have 2 or 3 others that do very occasionally, and I have 100+ that i haven't seen go wrong yet.

[android-developers] Re: OpenGL lockups in 2.2
Difficulties with one device I have no way of knowing how many makes/models of device this problem is on. I know that it happens all the time on my Samsung Galaxy (I9000). Others report exactly the same thing as being a feature of a number of HTC devices - these two make up a major part of the market I believe. I think I may well have two faults - one is the standard eglSwapBuffers hang, which none of the suggested fixes have had any effect on -square textures, different GLSurfaceView, wait, flush, finish etc. The second one, which I think might be related, is my intermittent framebuffer corruption, I am willing to accept this may be my fault in some way I have been unable to pinpoint. http://www.fordartworks.co.uk/dodgyS.png - the ractilinear dodgy area just above the left and right arrow buttons. smacks of throwing the baby out... At the moment, I am just hugely frustrated by the long list of problems I have faced with Android - halts on writing to SD card, gradients that don't work at one particular angle and so on. I have been a software designer and developer for over 25 years - parallel architecture research, trading room systems, real time etc (assembler, Fortran, Prolog, Occam, C, C++, Java) and I have never been so frustrated by any system - there has always been a different way of doing things, getting round problems. With this /these? OpenGL problem(s) it appears to be a black box. Without a genuine understanding of what is wrong, any fix is pure conjecture. should just be ignored I am extremely reluctant to put out an App that looks flakey or, much worse, shuts down people's phones. Ignoring a problem that I can't get round is not a viable solution I feel. plugging and unplugging the USB cable The USB cable stuff was a problem I had with very jerky OpenGL performance when the rendering load was heavy - this was caused by the CPU clock reducing when the GPU was active, I believe. seeing the behavior elsewhere I haven't experienced this problem with other programs on this phone. (I have not detected the problem on my Asus Transformer either, but I have tested that far less. It will also have very different performance characteristics.) I don't play games, 2D or 3D. Many of the openGL demonstrators, testers or benchmarkers don't stress the system sufficiently - i can get 50 or 60 fps. The problem is very timing dependent- i have one picture definition for my App that fails vaguely regularly - i have 2 or 3 others that do very occasionally, and I have 100+ that i haven't seen go wrong yet. I simply haven't the time to sit and fiddle about with a 3rd party app on the off-chance of catching a glitch. If I did - that would prove relatively little.

Alternatively, if you only have a few preferences, you should be able to
address them via their key directly.

You may want to check out a foreground service if you need a high priority service like playing music, etc. http://developer.android.com/reference/android/app/Service.html#startForeground%28int,%20android.app.Notification%29 This should make it a foreground application and help keep it from being destroyed for needed memory.
