How do I detect if the user has left my app?

Question

I am developing an Android app and I want to detect when the user exits my app either by clicking the Back button or the Home button.

Also, an event like onIn

Answer 1

Yes, check the lifecycle of the app - when a user minimizes or leaves a couple of methods get called onPause() onStop() and onDestroy()
