title: Asynchronous android GAE communication using restlet
body: <p>I would like to repeatedly (every second) ask for the message (object or value) to GAE (if android client did not create or change something there) from another android device. I need to check it pretty fast, but I know that it happens aproximately once in hour.</p>
  
  <p>I use restlet and I don't want to create new thread and poll by get from this thread every second, because this is very battery consuming. I also don't want to use C2DM. </p>
  
  <p>Is it somehow possible to do this? I have found something about NIO nonblocking http connectors here:

  <p>But here is described only the client side and I also don't know if this solution would even be possible to use on GAE and how. Does anyone know more about this approach? </p>
  
  <p>Thank you very much in advance.</p>
