On: Android vendors, don’t kill my app

[Izkata]

That sounds way over-complicated. Why not just keep a flag in the database that's updated during the Activity lifecycle?

Sorry, I didn't understand. We need a service side service to keep track of ack's that we received from the device. I am not able to understand how a db flag would help.

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.
