<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>
