In my Android app, every other time I launch my app, it crashes with OutOfMemory Exception

I have an Android app that in the onCreate() method, preloads a lot of graphics.

When I test my app on my HTC Aria and launch it, it runs fine. However, if I press the back button to exit my app, and then launch the app again, it crashes with an OutOfMemoryError: bitmap size exceeds VM budget. If I then launch the app for the third time (right after it has crashed) it launches fine. Then if I close and re-launch it, it crashes again with out of memory. It continues this every-other-time-crashing pattern forever if I keep trying.

I checked to see what life cycle methods were being called and onStop() and onDestroy() are both being called when I exit the app, yet I have a feeling that something is not yet being cleaned up and that by "crashing" the app when I try to launch it the second time, it somehow free's the memory.

Any thoug开发者_Python百科hts on what could be happening or how to remedy this? Please let me know if you need me to post more info. Thanks!

Info:

My app is fairly simple and only has 1 activity that plays some frame animations.

Maybe you are unnecessarily holding onto Context references? Check Avoiding memory leaks for some tips, as well as Attacking memory problems.

It sounds like something in the Activity life cycle is not quite right. Are you sure you have every start covered? http://developer.android.com/reference/android/app/Activity.html

You have onStop but do you have onDestroy? You're probably missing one of those that you need.

You may find some useful information the many answers to this question: Strange out of memory issue while loading an image to a Bitmap object

Also, I second the "Avoiding Memory Leaks" blog post. Especially if you can trigger the same problem with orientation changes. Using "this" context when creating display objects is a sneaky way to leak the Activity context. In my own app, I managed to leak a whole chain of contexts, and would very rapidly run out of memory when doing orientation changes.
