My ExoPlayer Methods which used to initialize exoplayer

 public void initializePlayer(Uri uri){
        Log.d(TAG,"Init Player Calling");

        if (player==null){
            Log.d(TAG,"Player Is Null Setting Up Player");
            player= ExoPlayerFactory.newSimpleInstance(
                    new DefaultRenderersFactory(context),
                    new DefaultTrackSelector(),
                    new DefaultLoadControl());
            playerView.setPlayer(player);
            player.addListener(componentListener);
            player.setPlayWhenReady(playWhenReady);
            player.seekTo(currentWindow,playbackPosition);

            MediaSource mediaSource=buildMediaSource(uri);
            player.prepare(mediaSource,true,false);
        }
    }

    private MediaSource buildMediaSource(Uri uri){
        return new ExtractorMediaSource(uri,
                new DefaultHttpDataSourceFactory("ua"),
                new DefaultExtractorsFactory(),null,null);

    }

I tried to Uri.parse(path) and file way as above but it still giving me ClassCastException . Please guide me how to play local storage file in exoplayer.

If you are not using HTTP, perhaps `DefaultHttpDataSourceFactory` is the problem. See also `FileDataSource`: http://google.github.io/ExoPlayer/doc/reference/com/google/android/exoplayer2/upstream/FileDataSource.html — CommonsWare, Nov 01 '17 at 00:15
I'm need to play streaming files and local files with audio. — androidXP, Nov 01 '17 at 08:23

I got the answer from google official Exoplayer repository that

The DefaultDataSource supports both local and Http sources. It automatically detects which one to use.

So i changed

private MediaSource buildMediaSource(Uri uri){
        return new ExtractorMediaSource(uri,
                new DefaultHttpDataSourceFactory("ua"),
                new DefaultExtractorsFactory(),null,null);

    }

to this

private MediaSource buildMediaSource(Uri uri){    
        return new ExtractorMediaSource(uri,
                new DefaultDataSourceFactory(context,"ua"),
                new DefaultExtractorsFactory(),null,null);

    }

DefaultDataSourceFactory detect streaming or local storage file automatically where DefaultHttpDataSourceFactory only works on streaming request.

UPDATE: As new version introduced (2.9.0). Some classes are deprecated also media sources. I am using new version of media source which plays almost every type of files (MP3,MP4,AVI and more)

 private MediaSource buildMediaSourceNew(Uri uri,int buildType){    
                DataSource.Factory datasourceFactroy = new DefaultDataSourceFactory(context, Util.getUserAgent(context,"Your App Name"));
                return new ExtractorMediaSource.Factory(datasourceFactroy).createMediaSource(uri);
}

`ExtractorMediaSource()` is deprecated, you should use `ExtractorMediaSource.Factory(DefaultDataSourceFactory(context, "ua")).createMediaSource(uri)` — Francis, Sep 17 '18 at 13:27
Yes and tried and tested on most of the format (audio/video) but not sure how to stream Youtube video in Exoplayer — androidXP, Sep 02 '19 at 22:56
Now the whole `ExtractorMediaSource` class is depreciated ("use ProgressiveMediaSource instead"). Dang, this player was already completed to use and all these continued fast changes are like salt to injury. — Damn Vegetables, Sep 17 '19 at 14:10

At the time of writing, ExtractorMediaSource is also deprecated.

The following solution works for me:

private MediaSource buildMediaSource(Uri uri) {
        MediaItem mediaItem = MediaItem.fromUri(uri);
        return new ProgressiveMediaSource.Factory(new DefaultDataSource.Factory(context)).createMediaSource(mediaItem);
    }

Example usage:

MediaSource mediaSource = buildMediaSource(Uri.parse(source));
exoPlayer.setMediaSource(mediaSource);
exoPlayer.setRepeatMode(repeat ? Player.REPEAT_MODE_ALL : Player.REPEAT_MODE_OFF);
exoPlayer.prepare();
exoPlayer.setPlayWhenReady(true);

Where source is the full path to a file in the private app data folder of my application, for example:

/data/data/com.example.someapp/files/demo.mp4

For me it does not work for files on the sdcard, for example: /mnt/sdcard/Movies/demo.mp4.
