<p>If your app plays audio, its important that your users can control the audio in a predictable
manner. To ensure a great user experience, its also important that your app manages the audio focus
to ensure multiple apps arent 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>

<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
