LibGDX game crash without errors (maybe AssetManager)

Question

i have a problem with my game. It's a endless run shooter/platform made with LibGDX (Scene2d and box2D).

I do tests with LG G2, LG G3, Galaxy s4, desktop and android emulator and i have no one problem, but when i try to start my game on Galaxy s3 i have a very strange problem. The game crashes with no error in android and no error in android studio, simply crashes... i think its very strange because i'm developing it since a year and i always got wich error makes it crashes.

I think it's AssetManager fault because crashes often happens during loading or just finished loading (sometimes after 20-30 seconds of playing), so i tried to load less stuff and its work. I added one piece per time and at a certain point i always got a crash. In total my assets are 11mb... not so much i think. The biggest asset is the background, 2 pieces 1920*1080, near 2*70kb (yes, 70kb)...

i have in Android Studio monitor, cpu use 10~20% kernel and 10~20%user and 10~12mb memory

Here it is where the crash happens, i hope to solve soon... Thanks guys!

Answer 1

When you use the Assetmanager , you should dispose the loaded textures after the use. This can be done by implementing the Disposable and AssetErrorListener interfaces .This way you get the method called dispose() to dispose the Assetmanager. Here is a quick example:

 public class gh implements Disposable,AssetErrorListener {

@Override
public void error(AssetDescriptor asset, Throwable throwable) {
    // TODO Auto-generated method stub

}

@Override
public void dispose() {


  //so you can release the AssetManager
    AssetManager.dispose;
    // TODO Auto-generated method stub

}

   }

In my experience, Box2D is a little fussy about dealing with things such as line lengths that are shorter than a hard-coded lower limit. I don't recall the lower limits, but you can find the checks in the Box2D source. Box2D will throw an exception which is unable to cross the JNI boundary and brings the whole process down with no explanation. Maybe add some of your own checks at points where you make calls to Box2D to make sure data is within the limits it will accept?
