Life cycle of Android Activity after pressing Back button

Suppose there is an activity A, from which you launch activity B. If, while in activity B, you hit the back button, you are popping activity B off the stack and B will not be in the activity stack any longer.

Whenever you push an activity to the stack, onCreate is called, and if you press back button, onDestroy is called, which means that the activity is flushed away.

The following activity call back methods are called, after pressing back button.

onPause()onStop()onDestroy()

The activity is destroyed.

And it recreates when launched again. These are the callback methods when it launches again.

onCreate()onStart()onResume()

I know the answer is been accepcted, still if this helps someone I am putting it.

When app is opening for the first time, by clicking the Icon

onCreate()onStart()onResume()

When home button is pressed

onPause()onStop()

when app is again opened by clicking the app icon or launched from recent

onRestart()onStart()onResume()

when app is opened and then back button is pressed

onPause()onStop()onDestroy()
