How to send a customized message through gcm and get its response?

I want to send customized message through gcm like a question with options and get the reply of that question from the receiver. In simple terms I want to make a voting app which uses GCM service for asking questions and getting response.

Have you checked Sending Upstream Messages? A code Block from the source Link:

try {
    Bundle data = new Bundle();
    data.putString("my_message", "Hello World");
    data.putString("my_action","SAY_HELLO");
    String id = Integer.toString(msgId.incrementAndGet());
    gcm.send(SENDER_ID + "@gcm.googleapis.com", id, data);
    msg = "Sent message";
}
catch (IOException ex) {
    msg = "Error :" + ex.getMessage();
}

You can add your Votes in data. Also you might wanna send your GCM token, that you receive in RegistrationIntentService.onHandleIntent(). This token can then be used by the server to uniquely identify you and send messages to you directly via GCM.

Check Downstream Messaging Via HTTP Post, your JSON will look something like this.

https://gcm-http.googleapis.com/gcm/send
Content-Type:application/json
Authorization:key=AIzaSyZ-1u...0GBYzPu7Udno5aA

{
    "data": {
        "score": "5x1",
        "time": "15:10"
     },
     "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1..."
}

Where "to" has the device's token.
