GCM Message Delivery Confirmation

Question

I am implementing push notifications with Google Cloud Messaging. I am simply testing with their demo applicaitons on official site. All is working well. But, has anyone idea of how to gurantee the delivery of message, in anyway? Or can we invoke server to let know once the message are delivered in device, and will it be reliable approach?

Take a look at the answer on Android GCM delivery monitoring.

"They don't guarantee delivery but they try for a max of 4 weeks to deliver the message depending on the duration you set in the message you send to Google's GCM servers and if you wish to let Google keep the data for eventual delivery of msg to the device in case the device was offline when the message was to be delivered."
