How do you use fragments?

There are two ways to add a fragment to an activity: dynamically using Java and statically using XML. Before embedding a “support” fragment in an Activity make sure the Activity is changed to extend from FragmentActivity or AppCompatActivity which adds support for the fragment manager to all Android versions.

How does the lifecycle of fragments work?

Each Fragment instance has its own lifecycle. When a user navigates and interacts with your app, your fragments transition through various states in their lifecycle as they are added, removed, and enter or exit the screen.
