android push notification in phone gap not getting notifications

Question

Hi I follow the steps below

1) I created the cordova project structure.
2) I added the platform( android).
3) I added the cordova plugin

cordova plugin add https://github.com/phonegap-build/PushPlugin.git#2.4.0

4) Bulid the cordova project.
5) Next I import the created app in android eclipse(4.4.2)
6) I wrote the code below in index.js file

 init: function(){
     alert("init");
    var pushNotification = window.plugins.pushNotification;

    pushNotification.register(successHandler, errorHandler, 
        {
            'senderID':'XXXXXXXXXX',
            'ecb':'onNotificationGCM' // callback function
        }
    );

    function successHandler(result) {
        console.log('Success: '+ result);
        alert(result);
    }

    function errorHandler(error) {
        console.log('Error: '+ error);
    }

     function onNotificationGCM(e) {
        alert("comming");
        if('registered' === e.event) {
            // Successfully registered device.
        }
        else if('error' === e.event) {
            // Failed to register device.
        }
    };

I am getting the respose as "OK".and i am not able call 'ecb': onNotificationGCM' // callback function

In Android console I am getting the bellow Message

This is the push notification flow:

1. your app request a registration to the remote Apple or Google server
2. if the registration is ok, the remove server returns a token, that identify this specific app on your device
3. you send this token to your server, saving it (eg on a db)
4. you send a push notification (from your server) calling Apple or Google services with the message and the tokens of the users you want to notify
5. these services push to your device/app a notification with the message

You must follow all these steps in order to have push notification working.

For android you need to catch the registration id (token) inside the registered event of the notification handler:

function onNotificationGCM(e) {
    alert("comming");
    if('registered' === e.event) {
        // Successfully registered device.
        console.log("regID = " + e.regid);
        // save/send this registration id on your server
    } else if('error' === e.event) {
        // Failed to register device.
    }
};

For iOS you need to catch it in the succesHandler of the register function.
