Cordova admob不展示广告

Question

我试图使用Cordova AdMob插件https://github.com/appfeel/admob-google-cordova使AdMob在可加载网页的Cordova Android应用上正常工作。

我将Google admob AppID赋予了代码的PublisherID。应用程序在移动设备上没有显示广告。

下面给出了代码。

var app = {
    // Application Constructor
    initialize: function() {
        document.addEventListener('deviceready', this.onDeviceReady.bind(this), false);
    },

    // deviceready Event Handler
    //
    // Bind any cordova events here. Common events are:
    // 'pause', 'resume', etc.
    onDeviceReady: function() {
        this.receivedEvent('deviceready');

        if (navigator.connection.type == Connection.NONE) {
            navigator.notification.alert('Check your internet connection!');
        } else {
        window.location="http://www.xxxxyyyyyzzzz.com";
        }


    // start of admob code
    admob.createBannerView({publisherId: "ca-app-pub-2275440647866479/xxxxxxxxxxx"});
    // end of admob code


    },

    // Update DOM on a Received Event
    receivedEvent: function(id) {
        var parentElement = document.getElementById(id);
        var listeningElement = parentElement.querySelector('.listening');
        var receivedElement = parentElement.querySelector('.received');

        listeningElement.setAttribute('style', 'display:none;');
        receivedElement.setAttribute('style', 'display:block;');

        console.log('Received Event: ' + id);
    }
};

app.initialize();

无错误消息。 android手机上没有广告。
