title: GCM - Notification Payload shown but how to handle "click"
body: <p>Ive implemented GCM using <a href="https://developers.google.com/cloud-messaging/concept-options#notifications_and_data_messages" rel="nofollow">GCM Messaging Concepts and Options - Notifications and data in the message payload</a>. </p>
  
  <p>Only-Data Payloads works well as expected. But now iam sending data and notification payload. The notification is shown on the device as expected. 
  BUT how to handle the user clicks/touches the notification. I know how to do that using the <code>data</code> payload. How is this done using the <code>notification</code> payload?</p>
