Does onDestroy() or finish() actually kill the activity?

Question

Actually I know i am asking about the simple and basic concept of Android. But I am a little bit confused about these finish() and onDestroy() meth

Answer 1

Finish() will literally finish your activity and if no references are present a GC will recover resources. onDestory() is actually a method that the system will call when it is destroying your activity and you are supposed to implement this function. You dont need to worry avout destroying your app , android does it for you.
