<p>If your app plays audio, it’s important that your users can control the audio in a predictable
|
||
manner. To ensure a great user experience, it’s also important that your app manages the audio focus
|
||
to ensure multiple apps aren’t playing audio at the same time.</p>
|
||
|
||
<p>After this class, you will be able to build apps that respond to hardware audio key presses,
|
||
which request audio focus when playing audio, and which respond appropriately to changes in audio
|
||
focus caused by the system or other applications.</p>

Playback</a></b></dt>
|
||
<dd>Learn how to ensure your users can control the volume of your app using the hardware or
|
||
software volume controls and where available the play, stop, pause, skip, and previous media

<dt><b><a href="audio-focus.html">Managing Audio Focus</a></b></dt>
|
||
<dd>With multiple apps potentially playing audio it's important to think about how they should
|
||
interact. To avoid every music app playing at the same time, Android uses audio focus to moderate
|
||
audio playback. Learn how to request the audio focus, listen for a loss of audio focus, and how to
|
||
respond when that happens.</dd>
