Answer 1

I’m not sure I completely understand your goals but I will take my best shot.

When you start a new activity B and then finish it, activity A will follow the activity lifecycle.

It sounds like you want your code in onCreate to run after B finishes but onCreate is only called during activity initialization. Perhaps if you move your switch logic to onResume(), which will be called after Activity B finishes, you will get the result you want.
