[android-developers] Android 2.3 Causes memory intensive app to crash
Hello all, I created an app which loads heavy 3d models into memory. This app runs fine on pre android 2.3 devices. However i updated my nexus one to Android 2.3, and now the app crashes. I get the error listed below. However this error is not really usefull. What should i do to fix this? Using less memory is difficult because i still need to load the 3d model into memory. 03-03 23:18:35.483: INFO/Min3D(17779): Renderer.onSurfaceCreated() 03-03 23:18:35.483: VERBOSE/Min3D(17779): RenderCaps - openGLVersion: 1.1 03-03 23:18:35.503: VERBOSE/Min3D(17779): RenderCaps - maxTextureUnits: 2 03-03 23:18:35.503: VERBOSE/Min3D(17779): RenderCaps - maxTextureSize: 4096 03-03 23:18:35.503: VERBOSE/Min3D(17779): RenderCaps - maxLights: 8 03-03 23:18:35.503: INFO/Min3D(17779): Scene.init() 03-03 23:18:35.503: VERBOSE/x(17779): ManagedLightList.reset() 03-03 23:18:35.503: DEBUG/WeaponDescripitonActivity(17779): initScene 03-03 23:18:35.503: INFO/Min3D(17779): Renderer.onSurfaceChanged() 03-03 23:18:35.543: ERROR/qsd8k.gralloc(96): /dev/pmem: no more pmem available 03-03 23:18:35.543: ERROR/qsd8k.gralloc(96): couldn't open pmem (Unknown error: 0) 03-03 23:18:35.543: ERROR/qsd8k.gralloc(96): gralloc failed err=Out of memory 03-03 23:18:35.543: WARN/GraphicBufferAllocator(96): alloc(800, 480, 1, 0303, ...) failed -12 (Out of memory) 03-03 23:18:35.543: DEBUG/GraphicBufferAllocator(96): Allocated buffers: 03-03 23:18:35.543: DEBUG/GraphicBufferAllocator(96): 0x3309b0: 1243.75 KiB | 800 ( 800) x 398 |1 | 0x0133 03-03 23:18:35.543: DEBUG/GraphicBufferAllocator(96): 0x351288: 544.00 KiB | 520 ( 544) x 256 |1 | 0x0133 03-03 23:18:35.543: DEBUG/GraphicBufferAllocator(96): 0x3c6a70: 1500.00 KiB | 800 ( 800) x 480 |1 | 0x0133 03-03 23:18:35.543: DEBUG/GraphicBufferAllocator(96): 0x3ef848: 1500.00 KiB | 800 ( 800) x 480 |1 | 0x0133 03-03 23:18:35.543: DEBUG/GraphicBufferAllocator(96): 0x3f63a0: 1243.75 KiB | 800 ( 800) x 398 |1 | 0x0133 03-03 23:18:35.543: DEBUG/GraphicBufferAllocator(96): 0x40f358: 723.75 KiB | 480 ( 480) x 386 |1 | 0x0133 03-03 23:18:35.543: DEBUG/GraphicBufferAllocator(96): 0x435788: 750.00 KiB | 480 ( 480) x 800 |4 | 0x0133 03-03 23:18:35.543: DEBUG/GraphicBufferAllocator(96): 0x47d640: 723.75 KiB | 480 ( 480) x 386 |1 | 0x0133 03-03 23:18:35.543: DEBUG/GraphicBufferAllocator(96): 0x4abf38: 1018.75 KiB | 800 ( 800) x 326 |1 | 0x0133 03-03 23:18:35.543: DEBUG/GraphicBufferAllocator(96): 0x4afd50: 1500.00 KiB | 480 ( 480) x 800 |2 | 0x0133 03-03 23:18:35.543: DEBUG/GraphicBufferAllocator(96): 0x4bd290: 118.75 KiB | 800 ( 800) x 38 |2 | 0x0133 03-03 23:18:35.543: DEBUG/GraphicBufferAllocator(96): 0x4d6cf0: 486.00 KiB | 375 ( 384) x 324 |1 | 0x0303 03-03 23:18:35.543: DEBUG/GraphicBufferAllocator(96): 0x4e0060: 1500.00 KiB | 480 ( 480) x 800 |2 | 0x0133 03-03 23:18:35.543: DEBUG/GraphicBufferAllocator(96): 0x504da0: 448.00 KiB | 432 ( 448) x 256 |1 | 0x0133 03-03 23:18:35.543: DEBUG/GraphicBufferAllocator(96): 0x506738: 1428.75 KiB | 480 ( 480) 03-03 23:18:35.543: ERROR/SurfaceFlinger(96): Layer::requestBuffer(this=0x63d530), index=1, w=800, h=480 failed (Out of memory) 03-03 23:18:35.543: ERROR/Surface(17779): Surface (identity=2407) requestBuffer(1, 0, 0, 1, 0203) returned a buffer with a null handle 03-03 23:18:35.543: ERROR/Surface(17779): getBufferLocked(1, 0, 0, 1, 0203) failed (Out of memory) 03-03 23:18:35.543: ERROR/Adreno200-EGL(17779): egliSwapWindowSurface: unable to dequeue native buffer 03-03 23:18:35.543: ERROR/qsd8k.gralloc(96): /dev/pmem: no more pmem available 03-03 23:18:35.543: ERROR/qsd8k.gralloc(96): couldn't open pmem (No such file or directory) 03-03 23:18:35.543: ERROR/qsd8k.gralloc(96): gralloc failed err=Out of memory -- You received this message because you are subscribed to the Google Groups Android Developers group.

@davemac could you share your copy somehow? A lot of people cannot test against honeycomb now.

This can be done with one TextView using the following method: http://developer.android.com/guide/appendix/faq/commontasks.html#selectingtext The problem is that its a widget and i only have access to the ui elements using the RemoteViews: http://developer.android.com/reference/android/widget/RemoteViews.html I was thinking of using a layout manager for this, but its impossible because textviews are always rectangular. So how do i do this? I know you helped twitter build their application.

I forgot to mention it.. but the point is of course that i want tot style the Author field differently that the other field. Else string concatenation would be the -duh- solution.

[android-developers] Re: AppWidgetManager updateAppWidget throws NullPointerException
Well it worked if i just did it from the AppWidgetProvider.onUpdate. And this service i wrote uses the same approach as Jeff Sharkey (Android Team Developer) uses in his example Widget: http://code.google.com/p/android-sky/source/browse/trunk/Sky/src/org/jsharkey/sky/UpdateService.java So what am i doing wrong? Should i still submit it to a handler? Can you explain me how todo that? On Jul 14, 10:44 am, Kostya Vasilyev kmans...@gmail.com wrote: Are you calling updateAppWidget from the worker thread?

Here is my code in the AppWidgetProvider class:
@Override
public void onUpdate(Context context, AppWidgetManager manager,
int[] appWidgetIds) {
log(onUpdate);
// If no specific widgets requested, collect list of all
if (appWidgetIds == null) {
appWidgetIds = manager.getAppWidgetIds(

}
// Request update for these widgets and launch updater service
HyvesWidgetService.requestUpdate(appWidgetIds);
context.startService(new Intent(context,

}
And code from the IntentService
/**
* Start this service, creating a background processing thread, if
not
* already running. If started with {...@link #ACTION_UPDATE_ALL},
will
* automatically add all widgets to the requested update queue.
*/
@Override

if (ACTION_UPDATE_ALL.equals(intent.getAction())) {
AppWidgetManager manager =
AppWidgetManager.getInstance(this);
Log.d(TAG, Requested UPDATE_ALL action);
requestUpdate(manager.getAppWidgetIds(new
ComponentName(this, HyvesWidgetProvider.class)));
}
onUpdate();
}
onUpdate calls an asynchronous api call, and a callback updates tthe
widget.

Turn the Service into an IntentService, and get rid of your own
thread. IntentService gives you your work on a background thread
automatically. See:
http://github.com/commonsguy/cw-advandroid/tree/master/AppWidget/Micr...
But i get a NullPointerException? What am i doing wrong? The Service
is not in a different process..
That is impossible to say without seeing your code.

[android-developers] Re: AppWidgetManager updateAppWidget throws NullPointerException
Request update is a very fast method
/**
* Request updates for the given widgets. Will only queue them up,
you are
* still responsible for starting a processing thread if needed,
usually by
* starting the parent service.
*/
public static void requestUpdate(int[] appWidgetIds) {
synchronized (lock) {
for (int appWidgetId : appWidgetIds) {
HyvesWidgetService.appWidgetIds.add(appWidgetId);
}
}
}
Yeah the onUpdate (may) fork antother thread.
I now solved it by waiting in the IntentService thread on an object
using a lock:
lock.wait();
and then if it is done i call lock.notify().
This should work i think... i'm trying it out right now.

Wait, whoa, what? You are already in a background thread. Is
onUpdate() forking yet another thread?

I have no idea what:
HyvesWidgetService.requestUpdate(appWidgetIds);
does, but that would seem to be taking too long.
And code from the IntentService
/**

not
* already running. If started with {...@link #ACTION_UPDATE_ALL},
will
* automatically add all widgets to the requested update queue.
*/

requestUpdate(manager.getAppWidgetIds(new
ComponentName(this, HyvesWidgetProvider.class)));
}
onUpdate();
}
onUpdate calls an asynchronous api call, and a callback updates tthe
widget.
Wait, whoa, what? You are already in a background thread. Is
onUpdate() forking yet another thread?

[android-developers] Re: AppWidgetManager updateAppWidget throws NullPointerException
Okay i have that now and i still get the nullpointerexception on an Nexus One. I still use a separate thread because the client libray i use does a asyncrhonous api call. But i syncrhonize it by an object lock. So it should work fine.. but it doesnt.

Make sure that you keep your code that gets the AppWidgetManager, creates/populates the RemoteViews, and calls updateAppWidget() all in a contiguous block of code, called on one thread, and it should work fine (barring supplying null values to methods on RemoteViews or something). -- Mark Murphy (a Commons Guy)http://commonsware.com|http://github.com/commonsguyhttp://commonsware.com/blog|http://twitter.com/commonsguy _The Busy Coder's Guide to *Advanced* Android Development_ Version 1.9 Available! -- You received this message because you are subscribed to the Google Groups Android Developers group.

Im calling it from the IntentService onHandleIntent method which should run in its own worker thread as the apidocs explain. It works on the emulator.

[android-developers] Re: AppWidgetManager updateAppWidget throws NullPointerException
Thanks... it was not a threading issue... i was calling
views.setImageViewBitmap(R.id.profile_image, icon);
with a null icon Most stupid mistake ever.
But i think it would be better if android throws a better exception
with a clear message.
Anyways... solved!
And a lot learned today!
Thanks to you all!

That is, updateAppWidget starts writing the RemoteViews object into a
Parcel, and crashes. Obviously the onUpdate() never returns, thus the ANR.
This runs on a separate thread, as can be seen further in the stack trace:
07-14 10:30:36.796: ERROR/AndroidRuntime(12077): at
com.hyves.android.widget.HyvesWidgetService.run(HyvesWidgetService.java:

07-14 10:30:36.796: ERROR/AndroidRuntime(12077): at
java.lang.Thread.run(Thread.java:1096)
Either it's really a threading problem, or else some data related to
RemoteViews is null (such as updateViews.setTextViewText(R.id.xxx,
null), or even the RemoteViews object itself is null). The latter one
should be easy to check by stepping through in the debugger.

This should only happen if onUpdate() of your AppWidgetProvider is
taking too long. This may be tied to some of the funky thread locking
you're trying to do.

[android-developers] Re: Garbage Collection Infinit Loop: clamp GC FOR MALLOC Grow heap loop
I am still not 100% sure what caused it but i solved it as follows.
I created a Service with a Handler. However that Handler was not in
its own thread.
So i had someting like:
public class ImageUploadService extends IntentService {
private Handler handler = new Handler()
The service was not run in its own process. This caused the handler to
be executed in the ui thread.
The solution was to wrap the handler in a thread like this:
class UploadLooperThread extends Thread {
public Handler mHandler;
public void run() {
Looper.prepare();
mHandler = new Handler();
Looper.loop();
}
}

That's all you need. I've found that the actual tick time doesn't
matter but the difference between the last tick and this tick is all
you need to have correct physics and most any update I've had to write
so far.
Game physics can work like this
updateGame(12) // moves physics 12ms forward
updateGame(15) // moves physics 15ms forward
updateGame(22) // moves physics 22ms forward
That's exactly what you want the tick delta for. I use that for all
movement, sound, collisions, animations and timers.
There's one exception - if your game cares about time of day. Then
you need the actual time of day calculated out to use for it, but
otherwise if the game runs in its own time, that'll do.

Hi all. What is most efficient way of keeping a check on time within a

Currently I create a new Date() when the game starts, and was thinking
of creating another Date() within the game thread and comparing it
with the first one. But with a screen refreshing at around 60fps
(hence a new date object each time), I can't help thinking this is
rather inefficient. What other ways are there of doing this?

Android 2.1 has API support for creating live wallpapers. This means that we can implemente our own live wallpapers w00t! However what i like to see is a Tutorial on creating such a live wallpaper. Is there going to be added one? What about battery live? Or maybe a link to the sourcecode to one of the live wallpapers in Nexus One? When i run a 2.1 emulator and choose a live wallpaper it says: No live wallpapers -- Anyway thanks for this nice peace of software. -- You received this message because you are subscribed to the Google Groups Android Developers group.

The SpriteMethodTest application shows the benefits of opengl,
the main benefit is:
If you have a lot of sprites / a lot of things happening at the same
time it is better to use opengl.
I am porting my game to opengl now. It was too slow on only the Canvas

[android-developers] Application Resources on SDCARD on install!! MUST HAVE, GOOGLE DO SOMETHING!!
A lot of developers and this problem: All resources in an APK are stored in the memory of the phone, it is impossible to force some resources to be saved on the sdcard. For example, check this use-case: I am creating a game with multiple levels a lot of sounds, menumusic and sprites. The size unpacked is now 6MB and the game is not even finished Users are already complaining: http://www.cyrket.com/package/com.tjerk.spacewars The only current solution is to download the data after installation on the sdcard and load the data from the sd card (requires your own data handling code, the convenience R class cannot be used). This solution is a no-go for a lot of developers because they simply donot have a server. The users may also find it weird that they have to install stuff after they installed the app. Another solution is to have a linux partition on your sdcard, but this requires a rooted phone and is only for advanced users. I know they are a lot of issues with installing part of the app on the sdcard (piracy etc). However if you only install application data on the sdcard, then there would be no problem. I suggest to create a .appname directory for each application that requires to save resources on the sdcard. Window users will not see that directory. If they delete the directory and restart the app they should get an alertbox that forces them to reinstall (or remove) the app. Seriouzly google, you have to add a feature that solves this problem, the android platform is a no-go for big games. And users can install a limited number of apps. What i want to now: Is this going to be implemented in the future? Or should i implemented the download-from-server solution. If you are going to implemented it in the next release than i will not waste time on implementing the download-from-server solution.

[android-developers] Sounds + Accelerometer = Weird accelerometer values: BUG?
I am developing a game. In which the user controls movement using the accelerometer. Sounds effects can also be enabled. However when laying the phone flat down and playing the game without the accelerometer gives nice 0,0,0 values. However when play WITH SOUNDS on, i get a buch of weird values: while the phone is NOT moving. This is really a big bug that makes life hard for Game Developers. I tried to take an avarge of the last 5 values from the sensor.. but this is not enough.. The harder the sounds plays: the higher the weird sensor values. When using the headphones: almost no weird values. Seems that sounds interferes with the accelerometer sensor.

[android-developers] Re: Sounds + Accelerometer = Weird accelerometer values: BUG?
Here is my damper.
HOWEVER: IT DOES NOT SOLVE THIS PROBLEM.
I am going to set the damping windows size to 3 or 4,

impossible with sounds on.
So Google Developers: What is causing this problem,
and how is it solved.???
Here my sensor damper:

* by damping them over an window of previous sensor values.
*
* The new sensor values are the average over all sensor values
* in the window.
*
* This class can be used as a workaround for the
* accelerometer sensor+sound bug in Android.
*
* A biger window means less fluctuation in the sensor values.
* However a side-effect of a large window is that it takes
* there is a delay in movement detection.

[android-developers] Dialog (built using AlertDialog.Builder) not complete when showing dialog in runOnUiThread
I have a game activity in which i have a dialog which is created in
the onCreateDialog method of the activity:
case VICTORY_DIALOG:
String[] items={Next Level, Play Again,
Exit};
AlertDialog.Builder builder = new
AlertDialog.Builder(this);
builder.setMessage(You won!)
.setCancelable(false)
.setItems(items, new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface
dialog, int id) {
if(id==0) {
SpaceWarsActivity.this.nextLevel();
} else if(id==1) {
SpaceWarsActivity.this.loadGame();
} else if(id==2) {
SpaceWarsActivity.this.onFinishGame();
}
}
});
dialog=builder.create();
break;
When the game ends i open this dialog from the game thread (not the ui
thread) with the following code:
activity.runOnUiThread(new
Runnable() {
public void run() {
activity.showDialog(VICTORY_DIALOG);
}
});
However... the dialog is just a small empty rectangle. No title, no
items, nothing!
The buttons (setPositiveButton,setNegativeButton,setNeutralButton) are
working though.
Wat am i doing wrong?
Thanks in advance

[android-developers] Re: Dialog (built using AlertDialog.Builder) not complete when showing dialog in runOnUiThread
Ok i solved it myself.
I use setMessage together with setItems.. this does not work
One should use setTitle in stead of setMessage.
I think the builder show throw an exception if somebody uses
a illegal combination of parts (in my case: message + items)
Anyway its a small issue, but a nasty bug if you dont see it :-)

SpaceWarsActivity.this.onFinishGame();
}
}
});
dialog=builder.create();
break;
When the game ends i open this dialog from the game thread (not the ui
thread) with the following code:
activity.runOnUiThread(new
Runnable() {
public void run() {
activity.showDialog(VICTORY_DIALOG);
}
});
However... the dialog is just a small empty rectangle. No title, no
items, nothing!
The buttons (setPositiveButton,setNegativeButton,setNeutralButton) are
working though.
Wat am i doing wrong?
Thanks in advance

I check the styles.xml that comes with android and found the following item name=windowBackground@android:drawable/ screen_background_dark/item However even this gives me the error message?!!@ What am i doing wrong?

[android-developers] SoundPool in Android 1.5: Still problems
A lot of developers where using the soundpool in 1.1: http://groups.google.com/group/android-developers/browse_thread/thread/b84abc998ad02aa2/1a92b99355ae623f?lnk=gstq=SoundPool#1a92b99355ae623f http://groups.google.com/group/android-developers/browse_thread/thread/e2f18cd7d53bcdfb/afb26f53697d222e?lnk=gstq=SoundPool#afb26f53697d222e In 1.5 it is nicely documented and Dave Sparks says the issues where resolved in 1.5: http://groups.google.com/group/android-developers/browse_thread/thread/b84abc998ad02aa2/1a92b99355ae623f?lnk=gstq=SoundPool#1a92b99355ae623f However my game (with 10 sounds) shows some erattic behaviour when using the soundpool. It looks like the sounds hiccup constantly. Also the sensor does not react that fluently. You can see the behaviour here: http://www.youtube.com/watch?v=X2JF-Sdm6jUeurl=http://www.youtube.com/user/lmjabreufeature=player_embedded The game works fine with the sounds turned of.. So probably this is a performance problem? I do not have a android phone now so i cant test it myself. But somebody recognizes this behaviour? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] android.util.SparseArray space time complexity properties
I need a map from int to certain objects. I wanted to use the HashMap, but in the documentation of SparseArray it says that SparseArray is intented to be *more efficient*: http://developer.android.com/reference/android/util/SparseArray.html However i think the documentation is not entirely correct and needs more info: When reviewing the sourcecode of SparseArray and comparing it with the HashMap i come to the following conclusion Source code of Sparse Array: http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob_plain;f=core/java/android/util/SparseArray.java;hb=HEAD For SpareArray: Time complexity for reads and writes on a map of size N is log2(N) + 1, However the time complexity for a HashMap of size N is C*N (where C is a constant) (according to the javadoc http://java.sun.com/j2se/1.4.2/docs/api/java/util/HashMap.html) So maybe SparseArray is more efficient with respect to space complexity it is not for time complexity. So for programs that need high performance a HashMap may be better. At least thats what i think. Am i right? Am i wrong? I need a very fast implementation for my game :-) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Loading bitmap: java.lang.OutOfMemoryError: bitmap size
Somebody tested my game (see http://spacewarsgame.wordpress.com) on a
real device,
however occasionaly this exception is thrown when running the main
game Activity.
This activity loads a lot of resources in GamePainter.init.
(I know it is better to load resources in a separate thread, i'm
woking on it,
however this exception is unrelated to that (i think))
I dont now what the cause of this exception is, some VM memmory
allocation problem.
Is there not enough memory? If so, why does it run sometimes and other
times not?

[android-developers] Events not catched on real device using Activity.dispatchEventType
Hello all!
I am creating a game in which the user can control a ship by
- Using DPAD
- Using touchscreen
- Using trackball
- And even using orientation events (roll pitch etc)
It all works on the emulator but when i open the game on a real device
then
the events (touch, trackball) do not work anymore.
I am catching evetns by overriding the dispatchEventType() methods.
This is the code in my Activity class that catches the events:
public boolean dispatchKeyEvent(KeyEvent e) {
super.dispatchKeyEvent(e);
return controller.onKeyEvent(e.getKeyCode(), e);
}
public boolean dispatchTrackballEvent(MotionEvent e) {
if(settings[2] || settings[3]) {
return controller.onTrackballEvent(e);
} else {
return super.dispatchTrackballEvent(e);
}
}
public boolean dispatchTouchEvent(MotionEvent e) {
if(settings[1]) {
return controller.onTouchEvent(e);
} else {
return super.dispatchTouchEvent(e);
}
}
I think the dispatchKeyEvent(..) method works fine, but the other ones
do not work on a real device.
They work without problems on the emulator.
What am i doing wrong?
I really do not understand it.
Thanks in advance.

[android-developers] Re: sound effect using SoundPool
By the way: try to use .ogg files, they are played better by android.
Also i had problems with playLoop(int resid),
sometimes the sample is looped, and sometimes it is not.
A possible usage of the SoundEffects class is by subclassing it.
The code from my example ( i am making a col game! :-) :
public class GameSounds extends SoundEffects {
private static GameSounds INSTANCE;
public static GameSounds getInstance(Context ctx) {
//return new GameSounds(ctx);
if(INSTANCE==null || INSTANCE.released)INSTANCE=new
GameSounds(ctx);
return INSTANCE;
}
private GameSounds(Context context) {
super(17, context);
addSound(R.raw.engage);
addLoopSound(R.raw.alarm2);
addSound(R.raw.fire);
addSound(R.raw.explosion1);
addSound(R.raw.explosion2);
addSound(R.raw.smallexplosion);
addSound(R.raw.mediumexplosion);
addSound(R.raw.lasergun);
addLoopSound(R.raw.machinegun1);
//addSound(R.raw.);

//addSound(R.raw.bigexplosion);
//addSound(R.raw.shortshoot1);
addSound(R.raw.shortshoot2);
//addSound(R.raw.gunload);
}
public void smallExplosion() {
play(R.raw.smallexplosion);
}
public void explosion() {
play(R.raw.mediumexplosion);
}

play(R.raw.explosion2);
}

play(R.raw.engage);
}
public void heal() {
play(R.raw.heal);
}
public void nextWave() {
play(R.raw.heal);
}
public void fireVoice() {
play(R.raw.fire);
}
public void fire() {
play(R.raw.smallexplosion);
}
public void fire1() {
//play(R.raw.shortshoot1);
}
public void fire2() {
//play(R.raw.shortshoot1);
}
public void startFire() {
playLoop(R.raw.machinegun1);
}
public void stopFire() {

For this and many other reasons, every developer should run their application on real hardware before considering it to be ready for for release to the public.

Re: I thought about decoupling the movement from the framerate (speed = pixels/second), but this requires the use for floats, which make the calculation rather slow. In a game you should never tie the speed of movement to the frame rate, because that will of course vary across different hardware. Even if we were doing a google phone and completely controlling the hardware, we'd want to release new hardware in the future that goes faster, and your game then wouldn't work well with it. I understand that. Also there should be no reason to need floats to deal with this, you can use fixed point integers. How should i do it. Supposei have the following: int BULLET_SPEED=30; // 30 pixels/second // then on a frameDraw long deltaT=thread.getFrameTime(); // the time it took to move to a new frame, in millis int movement=(BULLETSPEED*deltaT)/1000; /// v*t = d The problem here is that movement is always zero because the devision is done with 1000 (1 second). So either i use this: int movement=(int)((BULLETSPEED*deltaT)/(float)1000); Which required FLOATING POINT calculation. Or i make the bullet speed a float. But this also requires floating point calculation. So how is it done, without the need of floating points? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Does SoundPool work or has anyone successfully used it?
I also wanted to use the soundpool, but lack of documentation made it
impossible to use.
I tried it they way i would think it would work, but it didn't.
I am using mediaplayers now, i cannot play the same sound multiple
times concurrently, Too bad.
On 12 okt, 19:32, Robert Green [EMAIL PROTECTED] wrote:
I have a few more comments on this class.
1) Is it going to be officially supported?
2) Here are some problems I've found with it and workarounds I used:
Bug #1) Looping an mp3 crashes around the 8th loop but looping waves
seems to work fine.
Bug #2) SoundPool.stop(streamId) immediately crashes the app.
Bug #3) setRate() with a rate over 1.5 either doesn't work or also
crashes the VM with no exception.
My new workaround for lack of stop():
to stop a stream, call setLoop(streamId, 0) then setVolume(streamId,
0f, 0f). This will stop a loop after it's done but drop the volume so
it seems to the user to have quit right then. After that, you don't
need to call stop() because the stream will clean itself up from the
loop stopping. This worked for me.
Even if they haven't readied it for public use, it's the only suitable
API forsoundin games. I looked into using MediaPlayers but if you
have more than a couple of sounds and you need to be able to play the
samesounda few times concurrently, it's just not a feasible
solution.
I'm really surprised that there is no access to the audio buffer. How
are we supposed to write dynamic audio generation apps?
Androidreally needs 2 things to be competitive with the audio side:
1) Public access to the media decoders (so a dev can decode an mp3
into raw)
2) Public access to asoundstream output buffer (so a dev can pipe in
rawsounddata)

[android-developers] Playing Sounds, What is the fastest? PCM MP3?
I am playing sounds from resources using the MediaPlayer, the point is that multiple sounds play simultanously. This decreases the performance of the game, i used stereo 44100 hz mp3 sound. Now i changed it to WAV PCM 33800 (i think) mono. However this increases performance only a little (on the emulator). So what sounds-formats/codecs should i use.

[android-developers] Emulator Performance VS Real Phone Performance
I am writing a game, the movement in that game is based on the framerate. (speed = pixels/frame) The framerate depends on the speed of the device. I have the feeling that my emulator is running relatively slow compareed to a real phone, ( for example sound stutters). I am getting max 30 fps in a simple 2d game. How do i know wether the performance of the emulator really emulates the performance of a real phone? Or is it phone dependand? ( cause android is decoupled from a real phone ) ?
