What is the difference between Fragment and FragmentActivity?

Question

My question is apart from the obvious inheritance differences, what are the main differences between Fragment and FragmentActivity? To what scenarios are each class best sui

Answer 1

Well Fragment is good component that copy the basic behaviors of Activity, still not a stand-alone application component like Activity and needs to be attached to Activity in order to work.
