SandboxedPlayer player = new SandboxedPlayer(context, surfaceView);
player.setObserver(this, isReady -> {
    if (isReady) {
        player.loadVideoSource("http://example.com/video.mp4", null);
        TrackInfo textTrackInfo = player.getTextTrackInfo();
        if (textTrackInfo != null) {
            Log.d("Client", "Selected text track index: " + textTrackInfo.getSelectedIndex());
            Log.d("Client", "Number of text tracks: " + textTrackInfo.getTracks().size());
        }
    }
});

Return
