On: Android vendors, don’t kill my app

[Izkata]

If all you need is to detect it on the next boot to notify the user, as the prior comment said, then for example:

onCreate - check "running" flag, then set to true

onDestroy - set flag to "ended"

If onCreate saw the flag was already "running" before it was set, then you have a crash to recover from or a kill to notify the user about.
