In Chapter 4, “Building User Interfaces,” you learned how to use Activities, Fragments, layouts, and Views to construct a user interface (UI). To ensure that your UI is stylish, easy to use, and provides a user experience consistent with the underlying platform and other applications running in it, this chapter looks at ways to expand the user experience beyond the UI elements you design.

You'll start with the Action Bar, introduced in Android 3.0, a system UI component used to provide a consistent pattern for branding, navigation, and displaying common actions within your Activities. You'll learn how to customize the look of the Action Bar, as well as how to use it to provide navigation with tabs and drop-down lists.
