My guess would be that you have an SQLite cursor that you're not releasing when your Activity loses focus. I believe you have two options.
You say that you've tried to handle this in callback functions onRestart, onResume, etc. The problem is you're looking at the wrong end of the lifecycle. When the user hits the 'back' key, onPause is called. In onPause you should handling releasing resources and any other tear-down you need to do. I'd suggest reviewing the Activity lifecycle information ( http://code.google.com/android/reference/android/app/Activity.html ) . The other option is to use a managed cursor. To do this call Activity.startManagingCursor(yourCursor).
