Playing a music file while downloading it

I'm developing a music download App that basically does webscraping across differents torrent platforms and get the torrents. I want to play some music torrent files while I'm downloading them. I have a Service that basically takes care of doing all this. I set a buffer that waits until the torrent file Its at least 25% downloaded, then I use the MediaPlayer class to start playing the file. The music starts playing OK, but It stops after a while, as if It couldn't play more than that 25%. I tried using both the Android's MediaPlayer class and the FFmpegMediaPlayer library. I tried using several configs:

MediaPlayer mediaPlayer = new MediaPlayer();
        FileInputStream fis = null;
        try {
            fis = new FileInputStream(mCurrentTrack);
            mediaPlayer.setDataSource(fis.getFD());
            mediaPlayer.setAudioStreamType(AudioManager.STREAM_RING);
            mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                @Override
                public void onPrepared(MediaPlayer mediaPlayer) {
                    mediaPlayer.start();
                }
            });
            mediaPlayer.prepareAsync();
        } catch (Exception e) {
            Log.w(APP_TAG, String.format("Something went wrong while trying to play the torrent stream: " + e.toString()));
        }

mCurrentTrack is the path to the mp3 file that I downloaded into my Download folder in the external storage.

I tried using AudioManager.STREAM_MUSIC. I tried using the sync prepare() method and then calling the start() method. I triead opening the file with a new File(mCurrentTrack) before start playing It and setting It as readeable and writable. I tried many combinations, but always is the same, the music plays a few seconds and then stops. When I check the external storage, the file ends up being fully downloaded without trouble.

The library that I'm using to download the torrent files is this one TorrentStream-Android

Any tip or idea about how play this file while its being downloaded in the fly, would be appreciated.

As someone pointed out here. Using the ExoMedia player library solved the issue. Here's the snippet that I used to get it working:

compile 'com.devbrackets.android:exomedia:3.1.0'

final EMAudioPlayer mediaPlayer = new EMAudioPlayer (getApplicationContext());
            mediaPlayer.setOnPreparedListener(new OnPreparedListener() {
                @Override
                public void onPrepared() {
                    mediaPlayer.start();
                }
            });
            mediaPlayer.setDataSource(getApplicationContext(), Uri.parse(mCurrentTrack));
            mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
            mediaPlayer.prepareAsync();
