| <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> |

| <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 |
| playback keys.</dd> |
| |
| <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> |

| <dt><b><a href="audio-output.html">Dealing with Audio Output Hardware</a></b></dt> |
| <dd>Audio can be played from a number of sources. Learn how to find out where the audio is being |
| played and how to handle a headset being disconnected during playback.</dd> |
