title: Push Notifications Android. Application not running clarificaiton
body: <p>I'm developing an android app which implements push notifications using parse.</p>
  
  <p>I have a requirement that the app must 'still receive notifications if the app is not running', but what is 'not running' on android? from what I gather there are 3 ways in which an app can 'not run'.</p>
  
  <ol>
  <li>using the back button when the app is running</li>
  <li>going to applications->force quit</li>
  <li>holding down the back button and clearing the app from the list of recent apps </li>
  <li>using the home button.</li>
  </ol>
  
  <p>I have a broadcast receiver registered through manifest that fires only if the app has been closed using methods 1. and 4. </p>
  
  <p>Is that how it should work on android? or should my broadcast receiver trigger no matter how the app is closed?</p>
