title: SignalR - notifying a message when the application is in background or even killed
body: <p>The SignalR with the Java library is a great choice for realtime communication.
  Though it is possible to subscribe to hub on the onCreate and to close it.
  But what happens when the application is killed ( manually or automatically) or even the activity is dead.
  One solution is to use a service - that is basicly same as creating a GCM, OR the other one is to make juggling with push notifications, and send them also and than synchronize what is already sent to the user(bad thing)</p>
  
  <p>Suggestions ?  </p>
