Here is some useful info:

As far as when an activity is restarted -- if the process running the foreground activity goes away, the system will throw away that activity if it does not have a valid saved state for it (typically meaning it is paused and has given the system the result of onSaveInstanceState from before the pause). Once it has decided whether or not to throw away that activity, it will resume whatever activity is now at the top of the stack.
