<p>The <a href="https://developer.android.com/design/get-started/ui-overview.html#system-bars">
|
||
|
|
system bars</a> are screen areas dedicated to the display of notifications, communication
|
||
|
|
of device status, and device navigation. Typically the system bars (which consist of the status
|
||
|
|
and navigation bars, as shown in figure 1) are displayed
|
||
|
|
concurrently with your app. Apps that display immersive content, such as movies or images,
|
||
|
|
can temporarily dim the system bar icons for a less distracting experience,
|
||
|
|
or temporarily hide the bars for a fully immersive experience.</p>
|
||
|
|
|
||
|
|
<p>If you're familiar with the <a href="{@docRoot}design/index.html">Android Design
|
||
|
|
Guide</a>, you know the importance of designing your apps to conform to standard Android UI
|
||
|
|
guidelines and usage patterns. You should carefully consider your users'
|
||
|
|
needs and expectations before modifying the system bars, since they give users a
|
||
|
|
standard way of navigating a device and viewing its status.</p>
|
||
|
|
|
||
|
|
<p>This class describes how to dim or hide system bars across different versions of Android
|
||
|
|
to create an immersive user experience, while still preserving easy access to the system
|
||
|
|
bars.
