What is the usage of MediaSession in Android?

MediaSession is a class provided by Android for managing audio playback. It offers a seamless way to synchronize audio playback status with the user interface and media controllers.

MediaSession allows you to achieve the following functions:

1. Manage the audio playback status, including options such as play, pause, stop, fast forward, and rewind.
2. Receive control commands from media controllers such as headphone control, notification bar, lock screen interface, etc.
3. Send the media controller information about the audio playback status and current progress.
