Android onStop() not being called when starting a new activity in multi window mode

Issue

I am trying Android N multi window feature and I have found myself confused when starting a new activity. The problem is that when I start a new Activity, the onStop() callback is not being fired and when I press the back button from this new activity to return to the previous one, the previous one's onStart() callback is not being fired either.

Does anyone know what is happening?

--- Edited

It seems like that ActivityOptionsCompat.makeSceneTransitionAnimation has something to do with it.

Solution

Here is the android-lifecycle:

If you call another app in multi window mode, your application is still "partially visible", so onPause() is being called, but onStop() not.

At restart it's the same: onResume() is being called, but onStart() isn't.
