title: GCM not received at after idle
body: <p>My app receives the GCM messages instantly if the phone is connected to the network. But the devices does not receive the messages when user turns off the network and reconnects after a long gap (around 2 hrs).</p>
  
  <p>I have not added TTL, so assuming it would be 4 weeks.</p>
  
  <p>Sample message being sent :</p>
  
  <pre><code>{
      "registration_ids":["APA9xxx........."],  
      "delay_while_idle":false,  
      "collapse_key":"New Message",  
      "restricted_package_name":"com.sample.gcm",  
      "data":{  
          "app":2,  
          "product":"message",  
          "notif":"03lm9h"
      }
  }
  </code></pre>
  
  <p>Am I missing something do make it work when delivery is delayed?</p>
  
  <p>Kindly, point me to links which can help me in solving this problem.</p>
  
  <p>Thanks in Advance.</p>
