| <p>To create a dynamic and multi-pane user interface on Android, you need to encapsulate |
| UI components and activity behaviors into modules that you can swap into and out of |
| your activities. You can create these modules with the {@link android.app.Fragment} class, which |
| behaves somewhat like a nested activity that can define its own layout and manage its own |
| lifecycle.</p> |
| |
| <p>When a fragment specifies its own layout, it can be configured in different combinations with |
| other fragments inside an activity to modify your layout configuration for different screen |
| sizes (a small screen might show one fragment at a time, but a large screen can show two or |
| more).</p> |
| |
| <p>This class shows you how to create a dynamic user experience with fragments and optimize your |
| app's user experience for devices with different screen sizes, all while continuing to support |
| devices running versions as old as Android 1.6.</p> |
