  <p>I've only found the way of setting default melody for notifications:</p>
  
  <pre><code>RingtoneManager.setActualDefaultRingtoneUri(
                          SetSongDialogActivity.this,
                          RingtoneManager.TYPE_NOTIFICATION,
                          Uri.parse(songUrlStr));
  </code></pre>
