Native heap android OOM hardware acceleration

hardware-acceleration

first off I'm using a Nexus 7 (the 2013 one with the 1080p screen) running android 4.4(kitkat) and using eclipse with the adb pluggin for windows(64bit I think). My apps minSdkVersion is set to 11 and only operates in the landscape orientation.

The problem is I keep getting a OOM error after leaving my app run for a while. My dalvik heap remains constant at around 25~MB but using Debug.getNativeHeapAllocatedSize() and Debug.getNativeHeapSize() it says my native heap size is constantly increasing until the app crashes from a OOM error.

I'm using hardware acceleration by declaring android:hardwareAccelerated="true" in my manifest and using setLayerType( View.LAYER_TYPE_HARDWARE , null ) in my SurfaceView constructor to set it to be hardware accelerated.

(Using setLayerType( View.LAYER_TYPE_HARDWARE , null ) was my problem, I removed it and the memory leak stopped).

Weird thing is once I press the home button then go back to my app the native heap resets back to its initial value.

My proof the dalvik heap is remaining constant and the native heap is growing is from these messages in LogCat:

debug.native heap : allocated 191.45MB of 191.73MB (0.28MB free) debug.VM heap memory: allocated 23.00MB VM Heap Size: 31.00MB MaxHeapSize: 192.00MB : availMemory 634.95MB , lowMemory? false , threshold 96.00MB : canvas.isHardwareAccelerated() = true : GC_FOR_ALLOC freed 4566K, 30% free 22608K/32236K, paused 32ms, total 32ms : debug. ================================= : debug.native heap : allocated 197.01MB of 197.27MB (0.26MB free) : debug.VM heap memory: allocated 22.00MB VM Heap Size: 31.00MB MaxHeapSize: 192.00MB : availMemory 629.38MB , lowMemory? false , threshold 96.00MB

Then once the native heap is full i get the error:

I want to know how to prevent native heap memory leaks since i have no idea how to alloc on the native block over the dalvik heap.

I solved the issue by the way, just want to write it out to help other people since I couldn't find an answer to this from days of searching.

I spent days looking for a solution to why my native heap was increasing and my dalvik heap remained constant. After many questions and android documentation pages read i eventually tried to shut off hardware acceleration since I came across a OOM question relating the two already.

I removed the line setLayerType( View.LAYER_TYPE_HARDWARE , null ) from my SurfaceView and the problem went away. I added that line after some advice from some suggestions on trying to get hardware acceleration turned on and i never really understood what i was doing there. For some reason that line caused about 1mb/2seconds to be added to the native heap until my program crashed.

So to anyone who's looking for solutions to problems try one thing at a time and understand what your trying before you copy paste it to your code.

I still don't know why that caused the native heap to constantly increase though.

I hope this helps someone with OOM native heap issues.
