First of all, there are quite a few issues with the above code. var mPlayer = new MediaPlayer(activity); var mPlayer = MediaPlayer.create(context, "five.mp3"); The mPlayer variable is declared twice, which doesn't make much sense. Also, the second parameter of the "create" method is from the type Uri or int, not String. Finally, the URL of the player item has to be constructed natively, which is not as simple as providing the file name as in Titanium. Please follow the native Android docs to do this, as this is no Titanium- or Hyperloop related issue.
