    public static  int NOTIFICATION_ID = 1;
    private NotificationManager mNotificationManager;
    NotificationCompat.Builder builder;
    public static final String TAG = "GCM Demo";

    public GcmIntentService() {
        super("GcmIntentService");
        // TODO Auto-generated constructor stub
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        // TODO Auto-generated method stub
        Bundle extras = intent.getExtras();
        String msg = intent.getStringExtra("message");
        GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
        String messageType = gcm.getMessageType(intent);

         if (!extras.isEmpty()) {

             if (GoogleCloudMessaging.
                        MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {
                    sendNotification("Send error: " + extras.toString());
                } else if (GoogleCloudMessaging.
                        MESSAGE_TYPE_DELETED.equals(messageType)) {
                    sendNotification("Deleted messages on server: " +
                            extras.toString());
                // If it's a regular GCM message, do some work.
                } else if (GoogleCloudMessaging.
                        MESSAGE_TYPE_MESSAGE.equals(messageType)) {
                    // This loop represents the service doing some work.
                    for (int i=0; i<5; i++) {
                        Log.i(TAG, "Working... " + (i+1)
                                + "/5 @ " + SystemClock.elapsedRealtime());
                        try {

                    Log.i(TAG, "Completed work @ " + SystemClock.elapsedRealtime());
                    // Post notification of received message.
                    //sendNotification("Received: " + extras.toString());
                    sendNotification(msg);

    }

   }

my Receive Activity

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_receive);
    Intent intent = getIntent();

    name = (TextView) findViewById(R.id.name);
    deal = (TextView) findViewById(R.id.deal);
    valid = (TextView) findViewById(R.id.valid);
    address = (TextView)findViewById(R.id.address);
    String message = intent.getExtras().getString("message");
    try {
        json = new JSONObject(message);

        name.setText(stime);

        String slecturename = json.getString("deal");
        deal.setText(slecturename);

        String sroom = json.getString("valid");
        valid.setText(sroom);

        String sfaculty = json.getString("address");
        address.setText(sfaculty);


    } catch (JSONException e) {

        e.printStackTrace();
    }



      }

That's incorrect :

    mNotificationManager.notify(NOTIFICATION_ID++, mBuilder.build());

    mBuilder = new NotificationCompat.Builder(
            this).setSmallIcon(R.drawable.ic_stat_gcm)
            .setAutoCancel(true)
            .setContentTitle("GCM Notification")
            .setStyle(new NotificationCompat.BigTextStyle()
             .bigText(msg))
            .setContentText(msg);
    mNotificationManager.cancel(NOTIFICATION_ID);

You don't have to create another notification builder for cancelling the notification. You simply have to call mBuilder.setAutoCancel(true) for the original builder before calling mNotificationManager.notify.

Therefore you should replace that code with :

    mBuilder.setAutoCancel(true)
    mNotificationManager.notify(NOTIFICATION_ID++, mBuilder.build());

please check this code:

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
    .setSmallIcon(R.drawable.notification_icon)
    .setContentTitle("Event tracker")
    .setContentText("Events received")
NotificationCompat.InboxStyle inboxStyle =
        new NotificationCompat.InboxStyle();
String[] events = new String[6];
// Sets a title for the Inbox style big view
inboxStyle.setBigContentTitle("Event tracker details:");
...
// Moves events into the big view
for (int i=0; i < events.length; i++) {

    inboxStyle.addLine(events[i]);
}
// Moves the big view style object into the notification object.
mBuilder.setStyle(inBoxStyle);
...
// Issue the notification here.
