MismatchSenderId error from GCM (using GCM push no

Question

when I try to send message (from server to mobile using GCM push notification) I am getting following error. I have tried the all the solutions that have given in other posts in stackoverflow

{"multicast_id":xxxxxx,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"MismatchSenderId"}]}

1. I have done my registration in GCM

   Server key 1: xxxxxxxxxx Project ID: xxxxxx

2. In my android code I have set following (my package name is com.revu.revu)

   a. Manifest file:

        // When notification received from GCM, then activate this service
        <service
            android:name=".PushNotificationService"
            android:exported="false">
            <intent-filter>
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            </intent-filter>
        </service>

        <receiver
            android:name="com.google.android.gms.gcm.GcmReceiver"
            android:exported="true"
            android:permission="com.google.android.c2dm.permission.SEND">
            <intent-filter>
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
                <category android:name="com.revu.revu" />
            </intent-filter>
        </receiver>

<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<permission android:name="com.revu.revu.permission.C2D_MESSAGE"
    android:protectionLevel="signature" />
<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="com.revu.revu.permission.C2D_MESSAGE" />

b. I have got the registration ID from GCM server and I stored in my server.

c. When I try to send message to registration id with the API key (server key), I am getting above error (mismatchsenderId).

I have used following php code to send message

<?php
// API access key from Google API's Console
define( 'API_ACCESS_KEY', 'xxxxxxxxxxxxxxxxx');
$regId = "APA91bFidqJmnqm0GGmWRmkwB8Kn4fLJ0WPUTbWo3l2bbgQGNnzqbiYKyB4QJ-_JlvoA2tHFhgON2egA_1eJ82TA2sm38qdJVeP2Qk4CW1poxMcFu0emUC1Y_Lf3otKy6U5YAnn2ralS"; 
$registrationIds = array($regId);
// prep the bundle
$msg = array
(
	'message' 	=> 'here is a message. message',
	'title'		=> 'This is a title. title',
	'subtitle'	=> 'This is a subtitle. subtitle',
	'tickerText'	=> 'Ticker text here...Ticker text here...Ticker text here',
	'vibrate'	=> 1,
	'sound'		=> 1,
	'largeIcon'	=> 'large_icon',
	'smallIcon'	=> 'small_icon'
);
$fields = array
(
	'registration_ids' 	=> $registrationIds,
	'data'			=> $msg
);
 
$headers = array
(
	'Authorization: key=' . API_ACCESS_KEY,
	'Content-Type: application/json'
);
 
$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'https://android.googleapis.com/gcm/send' );
curl_setopt( $ch,CURLOPT_POST, true );
curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode( $fields ) );
$result = curl_exec($ch );
curl_close( $ch );
echo $result;

?>

Please help me, am I missing any step here.

I think it has something to do with the way you have set up API access for your project in the Google Developer Console,

Mismatched Sender ID is tied to a certain group of senders. when an application registers for GCM usage, it must specify which senders are allowed to send messages. Make sure you're using one of those when trying to send messages to the device. If you switch to a different sender, the registration IDs don't work. Happens when error code is 'MismatchSenderId'.
