title: Handling push notification while application is on background
body: <p>I am trying to fire a procedure or service when receiving a push notification, however I want to do this while the application is running in the background.</p>
  
  <p>I have already tested that it works with the application on foreground, but also need it to do some work when in background if receiving the notification.</p>
  
  <p>I have asked around and have been told that cannot be done, however i would like to ask here to confirm it, thanks in advance.</p>
