title: How do I stop the currently playing ringtone?
body: <p>I'm writing an app that sometime fires reminders that are supposed to play ringtones. I can start the ringtone OK, but can't stop it.
  I have a dismiss method in my fragment that should stop the currently playing ringtone and close the activity, but it doesn't work right.
  Here's what it does:</p>
  
  <pre><code>    RingtoneManager ringMan = new RingtoneManager(getActivity());
      ringMan.stopPreviousRingtone();
      getActivity().finish();
  </code></pre>
  
  <p>The method does get executed and the activity closes, but the ringtone just keeps on playing. What am I doing wrong?</p>
