Media3 Android Sample 🎥 📸 📺

The code is for an Android app that plays videos using ExoPlayer, a media player library for Android. The app has a single activity, MainActivity, which is responsible for creating and managing the player, as well as handling playback events.

Importing Necessary Packages:

The code begins by importing the necessary packages, including the core Android packages, the ExoPlayer library, and the data binding library.

Creating the Data Source Factory:

A data source factory is created using the DefaultHttpDataSource.Factory class. This factory will be used to create data sources for the player, which are responsible for fetching video data from the internet.

Initializing the Player:

The initPlayer() function initializes the ExoPlayer instance. It first creates a new ExoPlayer object using the ExoPlayer.Builder class. Then, it creates a MediaSource object based on the provided media URL. The media URL can be either a regular MP4 file or an HLS playlist. Finally, it sets the media source on the player, prepares the player, and adds a listener to handle playback events.

Handling Media Source Creation:

The getHlsMediaSource() and getProgressiveMediaSource() functions create MediaSource objects for HLS playlists and regular MP4 files, respectively. Both functions use the dataSourceFactory to create data sources for fetching video data.

Managing Player Playback:

The releasePlayer(), pause(), and play() functions are used to control the playback of the video. The releasePlayer() function releases the player resources, the pause() function stops playback, and the play() function resumes playback.

Restarting the Player:

The restartPlayer() function seeks the player to the beginning of the video and then resumes playback. This function is called when the playback ends.

Handling Playback Events:

The playerListener object implements the Player.Listener interface and is used to handle playback events. The onPlaybackStateChanged() method is called when the playback state changes. It handles the following playback states:

STATE_ENDED: Restarts the video playback STATE_READY: Starts playback and sets the player view STATE_BUFFERING: Does nothing STATE_IDLE: Does nothing

Defining Media URLs:

The MEDIA_URL and MEDIA_URL_HLS constants define the URLs of the videos to play. The MEDIA_URL is for a regular MP4 file, while the MEDIA_URL_HLS is for an HLS playlist.

Summary:

The provided code demonstrates how to use ExoPlayer to play videos in an Android app. It covers the creation of the player, handling of media sources, playback controls, and event management
