title: When would you use PendingIntent?
body: <p>I am trying to understand from the API the purpose of <code>PendingIntent</code>.</p>
  
  <p>Sometimes some methods I use requires this, I still did not get the idea right.</p>
  
  <p>Can anyone could explain? why can't i just use context?</p>
  
  <p>Thanks,</p>
