# Go to File > Build Settings
# Click *Build and Run* button for Android Platform to install{*}{{*}}
# Open the Unity app.

Resolution Note (fix version 6000.0.0b15):
Android: In multi-window mode, when "Run in background" is true and "Mute Other Audio Sources" is false, Unity will run and sound will always play. When "Run in background" is true and "Mute Other Audio Sources" is true, Unity will always run, but you will only hear the Unity app's sound if its window has focus. Sound will be muted when the Unity window is not in focus.
In multi-window mode, if "Run in background" is false, Unity will not run and sound will stop playing.
