title: Pending Intent types and the Alarm Manager
body: <p>I would like to set an alarm that will fire off once.</p>
  
  <p>There is a pendingintent flag named OneShot. It looks like that would be the right flag to use.</p>
  
  <p>But do I need to use that flag? If I use AlarmManager.SetTime(), then it should not repeat.</p>
  
  <p>What does OneShot offer?</p>
