MusicPlayer

MusicPlayer using glide, exo-player and dagger-hilt

App:

Layout:

1. MainActivity
2. HomeFragment
3. SongFragment

• when app launches MainActivity will be shown first. The part above bottom bar in the MainActivity is HomeFragment. HomeFragment is the starting point of the app.
• SongFragment is responsible for displaying song detail page. User can change seekbar position by moving cursor over it.

Connection between the ui and service:

• MusicServiceConnection is the class responsible for connecting ui and service.
• In MusicServiceConnection we call MediaBrowserCompat() which will Create a media browser for the specified media browse service.
• we call connect() along with it which will Connect to the media browse service. Internally, it binds to the service.
• after connect() is invoked callbacks provided to MediaBrowserCompat will be called .i.e. MediaBrowserCompatConnectionCallback().
• MediaControllerCompat is invoked in MediaBrowserCompatConnectionCallback.onConnected().
• MediaControllerCompat Allows an app to interact with an ongoing media session. Media buttons and other commands can be sent to the session. A callback may be registered to receive updates from the session, such as metadata and play state changes.
• MediaControllerCallback we listen to app interactions such as onPlaybackStateChanged, onMetadataChanged, etc. And update our ui accordingly.
