title: Android GCM not receiving messages when killing from task manager
body: <p>I implemented GCM push notifications for Android and I noticed that when I close the app from my Samsung Galaxy S3 task manager push notifications are not received anymore. The weird thing is that if I close the app by swiping it, it is also not visible anymore in the task manager but using the latter method I still receive the push notification.</p>
  
  <p>Also, if I restart the phone I still receive it. However if I close the app and restart the phone I do not receive the push.</p>
  
  <p>Does Android close more resources when closing the app from the task manager rather than by swiping? It is still strange however as when I restart the phone I am thinking that the app is still completely closed. Could it be that the Android system knows after a restart that it was not closed from the task manager?</p>
  
  <p>I search a bit around this issue and from what I found it looks like closing it from the task manager should still enable you to receive the push notification. Only when force closing the app the notifications would not be received.</p>
  
  <p>Any thoughts and workarounds maybe?</p>
