As Kostya obliquely pointed out, it is onPause() that should be called, not onStop(). There is the natural pair: onResume() and onPause(). If you are in the Resumed state, you should expect the phone to call onPause() before it ever calls onStop() (as it will when the Activity goes invisible).
Theoretically (that is, according to the strict wording of the lifecycle document), there are exceptions (onPause is killable), but they are very rare. Even on my memory-starved phone I have always seen onPause() called first. Many Activities will have nothing to do for onStop() anyway: serious data saving should have already been done on onPause(). But if you are using a BroadcastReceiver unique to your app, then you would unregister it in onStop().
