How to add Subtitles(.SRT files) to video in Exoplayer android?

i am working on a project where i should play .srt files along with video in android. I was working through the samples of Exoplayer but cant able to play .srt files with video.

The code i used is,

MediaSource mediaSource = new HlsMediaSource(Uri.parse("https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8"),
                mediaDataSourceFactory, mainHandler, null);

         Format textFormat = Format.createTextSampleFormat(null, MimeTypes.APPLICATION_SUBRIP,
                null, Format.NO_VALUE, Format.NO_VALUE, "en", null);

        Uri uri = Uri.parse("http://www.storiesinflight.com/js_videosub/jellies.srt");


        MediaSource subtitleSource = new SingleSampleMediaSource(uri, mediaDataSourceFactory, textFormat, C.TIME_UNSET);
// Plays the video with the sideloaded subtitle.
        MergingMediaSource mergedSource =
                new MergingMediaSource(mediaSource, subtitleSource);

        player.prepare(mergedSource);

Can anyone please suggest me solution for this or any tutorial links for the same. Your help is very much appreciated !

I know it's too late to answer this question, but if someone else falls for it, try this :

public class MainActivity extends AppCompatActivity {
SimpleExoPlayerView exoPlayerView;
SimpleExoPlayer exoPlayer;
String videoURL = "http://blueappsoftware.in/layout_design_android_blog.mp4";
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    exoPlayerView = (SimpleExoPlayerView) findViewById(R.id.exo_player_view);
    try {


        BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
        TrackSelector trackSelector = new DefaultTrackSelector(new AdaptiveTrackSelection.Factory(bandwidthMeter));
        exoPlayer = ExoPlayerFactory.newSimpleInstance(this, trackSelector);

        Uri videoURI = Uri.parse(videoURL);
        Uri subtitleUri=Uri.parse("https://firebasestorage.googleapis.com/v0/b/findandfix-2f4a9.appspot.com/o/Despacito%20Remix%20Luis%20Fonsi%20ft.Daddy%20Yankee%20Justin%20Bieber%20Lyrics%20%5BSpanish%5D.srt?alt=media&token=63344d04-af1c-4e2c-9d15-381bf7159308");
        DefaultHttpDataSourceFactory dataSourceFactory = new DefaultHttpDataSourceFactory("exoplayer_video");

        ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
        MediaSource mediaSource = new ExtractorMediaSource(videoURI, dataSourceFactory, extractorsFactory, null, null);

        // Build the subtitle MediaSource.
        Format subtitleFormat = Format.createTextSampleFormat(
                null, // An identifier for the track. May be null.
                MimeTypes.APPLICATION_SUBRIP, // The mime type. Must be set correctly.
                null,
                Format.NO_VALUE,
                Format.NO_VALUE,
                "en",
                null); // The subtitle language. May be null.

        MediaSource subtitleSource =new SingleSampleMediaSource(subtitleUri, dataSourceFactory, subtitleFormat, C.TIME_UNSET);

        MergingMediaSource mergedSource =
                new MergingMediaSource(mediaSource, subtitleSource);

        exoPlayerView.setPlayer(exoPlayer);
        exoPlayer.prepare(mergedSource);
        exoPlayer.setPlayWhenReady(true);
    }catch (Exception e){
        Log.e("MainAcvtivity"," exoplayer error "+ e.toString());
    }

}

I have given a lots of efforts for this and finally concluded to the solution...
Sharing here for the reference

Srt file format ref link - http://www.storiesinflight.com/js_videosub/jellies.srt

Solution which finds a way for me - https://github.com/google/ExoPlayer/issues/3869#issuecomment-367067013

Adding Exoplayer code here

// initialize exoplayer
private void initializeExoPlayer() {
    if (player == null) {
        video_view = (PlayerView) findViewById(R.id.video_view);

        // 1. Create a default TrackSelector
        LoadControl loadControl = new DefaultLoadControl(
                new DefaultAllocator(true, 16),
                VideoPlayerConfig.MIN_BUFFER_DURATION,
                VideoPlayerConfig.MAX_BUFFER_DURATION,
                VideoPlayerConfig.MIN_PLAYBACK_START_BUFFER,
                VideoPlayerConfig.MIN_PLAYBACK_RESUME_BUFFER, -1, true);

        BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
        TrackSelection.Factory videoTrackSelectionFactory =
                new AdaptiveTrackSelection.Factory(bandwidthMeter);
        TrackSelector trackSelector =
                new DefaultTrackSelector(videoTrackSelectionFactory);
        // 2. Create the player
        player = ExoPlayerFactory.newSimpleInstance(new DefaultRenderersFactory(mContext), trackSelector, loadControl);
        video_view.setPlayer(player);

    }
}


public void buildMediaSource(String videoUrl, final String questionVideoThumbnail) {


    Uri mUri = Uri.parse(videoUrl);
    Uri srtUri = Uri.parse("http://www.storiesinflight.com/js_videosub/jellies.srt");

    // Measures bandwidth during playback. Can be null if not required.
    DefaultBandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
    // Produces DataSource instances through which media data is loaded.
    DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(mContext,
            Util.getUserAgent(mContext, getString(R.string.app_name)), bandwidthMeter);
    // This is the MediaSource representing the media to be played.
    MediaSource videoSource = new ExtractorMediaSource.Factory(dataSourceFactory)
            .createMediaSource(mUri);
    // Prepare the player with the source.

    Format textFormat = Format.createTextSampleFormat(null, MimeTypes.APPLICATION_SUBRIP,
            null, Format.NO_VALUE, Format.NO_VALUE, "en", null, Format.OFFSET_SAMPLE_RELATIVE);
    MediaSource textMediaSource = new SingleSampleMediaSource.Factory(dataSourceFactory)
            .createMediaSource(srtUri, textFormat, C.TIME_UNSET);
    MergingMediaSource mediaSource = new MergingMediaSource(videoSource, textMediaSource);

    player.prepare(mediaSource);
    player.setPlayWhenReady(true);
    player.addListener(this);

I just edit exoplayer example in there Player activity such like... and its working for me...

SubtitleView subtitleView=(SubtitleView)findViewById(com.google.android.exoplayer2.R.id.exo_subtitles); 
player.setTextOutput(new ComponentListener());

public class ComponentListener implements TextRenderer.Output{
  @Override
  public void onCues(List<Cue> cues) {
    if (subtitleView != null) {
        subtitleView.onCues(cues);
    }
  }

}

To show/hide the subtitleView:

subtitleView.setVisiblity(Visible/Gone);
