Connect My Exist Server To Gcm

I developed a client on android app and a server, but now I discovered the GMC- 'Google Cloud Messaging for Android' Is there any way to connect the GCM to my server, without chang

Solution 1:

You can send GCM messages from your Java Server. The simplest way is to use the server library supplied by Google (gcm-server.jar).

The code for sending a message is as simple as :

Sendersender=newSender(apiKey);
Messagemessage=newMessage.Builder()
    .delayWhileIdle(true)
    .addData("key1", "value1")
    .addData("key2", "value2")
    .build();
Resultresult= sender.send(message, registrationId, numOfRetries);

In addition, you'd have to check the result, to see if your message was accepted or rejected by GCM server.

This example shows how to send a message to a single device. There's a similar way to send the same message to multiple devices.

Finally, you'll have to implement some web service that accepts a registration ID from your app, and saves it in your DB.
