The AudioManager class has a method abandonAudioFocus() and another method requestAudioFocus(). I wonder what is audio focus? And what happens if an AudioManager object gets the audio focus or lost the audio focus?
Thank you!

Audio focus in Android 8. 0 through Android 11. Beginning with Android 8.0 (API level 26), when you call requestAudioFocus() you must supply an AudioFocusRequest parameter. The AudioFocusRequest contains information about the audio context and capabilities of your app.
Audio Manager in android is a class that provides access to the volume and modes of the device. Android audio manager helps us adjust the volume and ringing modes of devices based on our requirements. The modes that are well known to us, that are Ringing, Vibration, Loud, Silent, etc.
You can easily control your ringer volume and ringer profile i-e:(silent,vibrate,loud e.t.c) in android. Android provides AudioManager class that provides access to these controls. In order to use AndroidManager class, you have to first create an object of AudioManager class by calling the getSystemService() method.
It has to do with priority when using the speakers, to prevent playing many things at once or being overridden. If you requestAudioFocus(), you're declaring that you want control. You can then listen with onAudioFocusChange(int focusChange) to see if anything else tries to play a sound. You may forcefully lose focus (like during a phone call) but then you can gain it later. You should abandonAudioFocus() when you're finished.
