Bug in Livewallpaper test #1132

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
This happens with the Livewallpaper.java in libgdx tests.

Everytime I enter Settings - Display - Wallpapers - Home screen wallpaper - 
Live wallpapers - MyWallPaper -> A new instance of the wallpaper is created. 
The old instances don't seem to get destroyed. This happens with the 
Livewallpaper.java in libgdx tests. The end result is that the wallpaper takes 
more and more memory, which does not seem to get released.

The following is taken by "Dump HPROF file" in eclipse after visiting few times 
the menu:

8 instances of "com.badlogic.gdx.tests.WaterRipples", loaded by 
"dalvik.system.PathClassLoader @ 0x405153d0" occupy 1 347 200 (36,45%) bytes. 

Biggest instances:
•com.badlogic.gdx.tests.WaterRipples @ 0x40514028 - 168 400 (4,56%) bytes. 
•com.badlogic.gdx.tests.WaterRipples @ 0x40526ac0 - 168 400 (4,56%) bytes.

•com.badlogic.gdx.tests.WaterRipples @ 0x40687870 - 168 400 (4,56%) bytes. 

These instances are referenced from one instance of 
"java.util.HashMap$HashMapEntry[]", loaded by "<system class loader>"

Can you share more information about the device you are using to test this and 
the Android version?

The problem is the commented row in the AndroidLiveWallpaperService.java

// app.onDestroy()

but if we use it we have some other problem.

I have workaround, it is kill the app if we change the wallpaper at least:

if (runningEngines == 0) {
   app.onDestroy();
}
