When does android activity finish starts

问题

When we call activity.finish() will the next android life cycle method be executed?

1) Lets say user clicks on a button
onUserInteraction() we have called activity.finish()
will the action dispatched to the onClicked listener of the button?

2) lets say onStart() we have called activity.finish()
will activity.OnResume() be called?

When the Activity first time loads the events are called as below:

onCreate()
onStart()
onResume()

When you click the back button OR try to finish() the activity the events are called as below:

onPause()
onStop()
onDestroy()

When you click on Phone button the Activity goes to the background & below events are called:

onPause()
onStop()

Exit the phone dialer & below events will be called:
