Android Push Problem with gcmjs Module

Hello, i'm using the "iamyellow gcmjs" module to receive push notifications on Android. The PHP-Script for sending works fine and Google Servers say no Error, but the message i've sended doesn't appear on the Phone. I know that in the ti.CloudPush module you have to turn the Pushnotifications on, to receive the push notifications. Do i have to do this in that modul, too? And if yes, how? Thanks!

gcm.registerForPushNotifications({
    success: function (ev) {
        // on successful registration
        alert('Success! your device Token is: ' + ev.deviceToken);        
    },
    error: function (ev) {
        // when an error occurs
        alert('******* error, ' + ev.error);
    },
    callback: function () {
        // when a gcm notification is received WHEN the app IS IN FOREGROUND
        alert('hellow yellow!');
    },
 
    data: function (data) {
 
        alert('******* data (resumed) ' + JSON.stringify(data));
    }
});
