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.

Answer 1

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);
}
