When I am testing the Parse Push to my Android phones the push notification come through as long as the app runs. 
If the app is closed: I just get a message saying `<App name> has stopped.` - I don't receive any of the pushes - but still got the stop notification popup. I have followed the Quickstart guide from Parse step by step.
