How to implement Exoplayer 2.11.1 in android?
I also faced this problem and this my solution
Declaration
private val exoPlayer: SimpleExoPlayer by lazy { SimpleExoPlayer.Builder(this).build()}
Play Song
private fun prepareExoPlayerFromURL(url: String) {
val dataSourceFactory =
DefaultDataSourceFactory(this, Util.getUserAgent(this, resources.getString(R.string.app_name)), null)
val extractorsFactory = DefaultExtractorsFactory()
// val audioSource = ExtractorMediaSource(uri, dataSourceFactory, extractorsFactory, null, null)
val concateMediaSource = ConcatenatingMediaSource()
// to play from song list
for (i in mSongList) { // song list song arraylist
val mediaSource = ProgressiveMediaSource
.Factory(
DefaultDataSourceFactory(this, dataSourceFactory),
DefaultExtractorsFactory()
)
.createMediaSource(Uri.parse(i.musicFile)/*Uri.parse(i.uri)*/)
concateMediaSource.addMediaSource(mediaSource)
}
// to play single song
/* val audioSource = ProgressiveMediaSource
.Factory(
DefaultDataSourceFactory(this, dataSourceFactory),
DefaultExtractorsFactory()
)
.createMediaSource(Uri.parse(url))*/
exoPlayer.prepare(concateMediaSource/*audioSource*/)
exoPlayer.seekToDefaultPosition(songPosition)
exoPlayer.playWhenReady = true
setNotification()
}
to set listener of player and notification
private fun setListoner() {
exoPlayer.addListener(object : Player.EventListener {
override fun onPlayerStateChanged(playWhenReady: Boolean, playbackState: Int) {
when (playbackState) {
Player.STATE_BUFFERING -> Log.e(TAG,"STATE_BUFFERING")
Player.STATE_ENDED -> Log.e(TAG,"STATE_ENDED")
Player.STATE_IDLE -> Log.e(TAG,"STATE_IDLE")
Player.STATE_READY ->{
if (playWhenReady) {
Log.e(TAG, "PlaybackStatus.PLAYING")
} else {
Log.e(TAG, "PlaybackStatus.PAUSED")
}
}
else -> Log.e(TAG,"PlaybackStatus.IDLE")
}
}
})
}
to Kill player
private fun onDestroy() {
if (exoPlayer != null) {
exoPlayer.release()
exoPlayer = null
mediaSource = null
}
}
for more detail you can see official documentation
The Universal Music Player uses ExoPlayer for local audio playback.

For Java Guys (Long Live Java)
In Activity
private PlayerView epPlayerView = findViewById(R.id.design_reference);
The Public Function
public static void runExoPlayer(PlayerView epPlayerView,
String url,
Context context) {
Uri videoUri = Uri.parse(url);
SimpleExoPlayer exoPlayer = new SimpleExoPlayer.Builder(context).build();
epPlayerView.setPlayer(exoPlayer);
MediaItem mediaItem = MediaItem.fromUri(videoUri);
exoPlayer.clearMediaItems();
exoPlayer.setMediaItem(mediaItem);
exoPlayer.prepare();
exoPlayer.setPlayWhenReady(true);
}
Build Gradle

With the new update, you can create a simple player instance using SimpleExoPlayer.Builder
:
simpleExoplayer = SimpleExoPlayer.Builder(context).build()
You can also supply the Builder
with different arguments. See https://exoplayer.dev/doc/reference/com/google/android/exoplayer2/SimpleExoPlayer.Builder.html
You can use this simple custom class I created to help you get started.
class ExoPlayerHelper(
private val playerView: PlayerView,
onError: (ExoPlaybackException) -> Unit,
onPlayerBuffer: (Boolean) -> Unit
) {
private var exoPlayer: ExoPlayer? = null
private var mediaSource: ProgressiveMediaSource? = null
private val playerListener = object : Player.EventListener {
override fun onPlayerError(error: ExoPlaybackException) {
super.onPlayerError(error)
onError(error)
}
override fun onPlayerStateChanged(playWhenReady: Boolean, playbackState: Int) {
super.onPlayerStateChanged(playWhenReady, playbackState)
onPlayerBuffer(playbackState == Player.STATE_BUFFERING)
}
}
fun initializePlayer(url: String) {
exoPlayer = SimpleExoPlayer.Builder(playerView.context).build()
exoPlayer!!.repeatMode = Player.REPEAT_MODE_ALL
exoPlayer!!.addListener(playerListener)
playerView.player = exoPlayer
val userAgent =
Util.getUserAgent(playerView.context, playerView.context.getString(R.string.app_name))
mediaSource = ProgressiveMediaSource
.Factory(
DefaultDataSourceFactory(playerView.context, userAgent),
DefaultExtractorsFactory()
)
.createMediaSource(Uri.parse(url))
exoPlayer!!.prepare(mediaSource!!, true, false)
exoPlayer!!.playWhenReady = true
}
private fun killPlayer() {
if (exoPlayer != null) {
exoPlayer!!.release()
exoPlayer = null
mediaSource = null
playerView.player = null
}
}
}
