android - What method is being called when I close an app

Question

I read all about the activity lifecycle and it's methods.

I still couldt find an answer: When I close my app, from the "open apps" menu (in galaxy4 it's a long press on the home button, in nexus5 it's the right button ...) what method is being called? if any?

In other words, my activity is launching a service. I want to terminate the service if the app (activity) is being closed. (onDestory is not reliable at all as said many times here before)

Thanks in advance!

Answer 1

onPause() is the only method that is called always. From onPause() state Android OS can kill this app for many reasons bypassing onStop and onDestroy. I don't think we can control this behavior of unexpected termination smoothly. Service can check for the state of the application periodically.
