They are using Fragments and Floating Action Buttons.

Also just for your information, unless you specifically call finish() on an activity, it will only get stopped when the new activity is started. When you return, it will go back to onResume() state.

Please look into activity life cycle and Fragment Life cycle to know about these things more clearly. The faster you have a clear idea about these, the easier it will be in the long run

NOTE: When it is on the home screen, It is an window running on top of the background service with a floating window , while inside the app it is a Fragment.
