Authenticated MediaPlayer

Question

Trying to stream a video from an external server.

  _mediaPlayer = new MediaPlayer();
  _mediaPlayer.setDataSource( this, Uri.parse( _uri ) );

Works fine for an openly accessible server, but throws an Exception when the server requires authentication. I've looked at the code inside setDataSource and haven't found any way to set a cookie programmatically for a ContentResolver.

        ContentResolver resolver = context.getContentResolver();
        fd = resolver.openFileDescriptor(uri, "r");

Any thoughts?
