Serious honeycomb hardware-acceleration memory issues

Im currently creating an app for honeycomb, but i'm getting significant problems i'm suspecting is with memory used by the openGL renderer.

Situation is i've got a scrollview that holds multiple container views (can be somewhat much, like 20); those container views each consist of like 6 custom views that have their layertype set to hardware accelerated by this.setLayerType(View.LAYER_TYPE_HARDWARE, null); (if I don't set it everything gets rendered all messed up with images missing or being drawn at wrong places etc). I also have a videoview that shows a video.

Now when I the app gets destroyed and created again (particularly on rotation) the app just dies a seriously horrible death without any debuggable errors except that the logs show a lot of GCs and loads of other stuff concerning graphics buffers being out of memory and all kinds of stuff dying:

So the question is, how can i make sure this doesn't happen? And specifically:

• Do i need to take particular care of caches and such, how?
• Do i have to limit my amount of hardware accelerated views?

Hardware layers are very costly in terms of memory. You should only enable them temporarily on views (for the duration of an animation for instance.) To get in the state you are describing your app must use more than 256+32 MB of video memory on a Xoom tablet. Also, if you are using WebView, be careful as it uses quite a bit of memory itself.
