title: Correct JSON format for GCM message
body: <p>heres my JSON</p>
  
  <pre><code>   var postData = 
                       "{ \"registration_ids\": [ \"" + pushNotificationState.RegistrationId + "\" ], "+
                           "\"data\": {\""+ pushNotificationState.NotificationData.NotificationData + "\"}";
  </code></pre>
  
  <p>registration Id and notification data are variables. I'm getting a 400 response from the GCM sever saying JSON is incorrect format. Can anyone pick where I have gone wrong?</p>
  
  <p>Cheers</p>
