How to implement Exoplayer 2.11.1 in android?


i am trying to implement exoplayer this is my exoplayer version

implementation 'com.google.android.exoplayer:exoplayer:2.11.1'

i am creating a music player app and i don't know anything about exoplayer i am trying to implement exoplayer from last 2 days but it's not working. i couldn't understand anything in the official documentation .

i find many example and tutorial but it's all about playing video using exoplayer. many example's are using deprecated methods.

I am trying to implement using this tutorial but many of methods are deprecated so it's not working EX.

simpleExoplayer = ExoPlayerFactory.newSimpleInstance(
            DefaultRenderersFactory(this),
            DefaultTrackSelector(adaptiveTrackSelectionFactory),
            DefaultLoadControl()
        )

can anyone suggest me where to start or how do i build music streaming app using latest version of exoplayer.

Any help would be highly appreciated.


Solution

  • 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
            }
        }
    }
