Activity provides a number of lifecycle callback methods that allow it to know that a state has changed from being created to being destroyed. Based on these callbacks, you can decide the behaviour of Activity when the user enters, leaves, or re-enters the Activity.
In this coffee break codelab, you'll explore:
-
Overview of Activity and Android components
