Playing getExternalFilesDir mp3 using exoplayer

Question

I am fairly new to exoplayer and I having some difficulties playing audio files (specifically mp3) via external files directory in android.

        val trackSelector = DefaultTrackSelector(this)
        trackSelector.setParameters(
            trackSelector.buildUponParameters().setMaxVideoSizeSd()
        )
        val player : SimpleExoPlayer = SimpleExoPlayer.Builder(this).setTrackSelector(trackSelector).build()


        videoView.player = player
        // Create a data source factory.
        val dataSourceFactory: DataSource.Factory = DefaultDataSourceFactory(this)
        // Create a progressive media source pointing to a stream uri.
        val mediaSource: MediaSource = ProgressiveMediaSource.Factory(dataSourceFactory)
            .createMediaSource(MediaItem.fromUri(Uri.fromFile(getExternalFilesDir("app_tracks/helloaudio.mp3"))))

        player.setMediaSource(mediaSource)
        player.playWhenReady = true
        player.seekTo(0, 0)
        player.prepare()

And it gave me an error - Source error

I check the audio file whether is exists using isExist method, and it return true to me.

I appreciate your help.

What is the android version? You getting file not found exception< looks like you trying to get your file wrong way or it is not exist. If you are using android 8+ you suppose to use FileProvider to get Uri, not Uri.fromFile() code example:

final Uri uri = (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) ?
                FileProvider.getUriForFile(context, packageName + ".provider", file) : Uri.fromFile(file);

in manifest:

xml/file_paths (in res folder):
