ngCordova and $cordovaAdMob

ngCordova is a very useful and well done project, but unfortunately some extensions are not well documented.
Personally I found a bit of difficulty installing the module AdMob
First I used this plugin:
https://github.com/floatinghotpot/cordova-plugin-admob
and not the version “pro” that appears in the documentation
Thereafter, you must add the following code just after:

ionicPlatform.ready $ (function ()
 …. 

the code in question is:

var ad_units =
  ios: {
     banner: ‘app-ca-pub-1499928428419652/751861492' 
  } 
 }; 
 var options = {
      publisherID: ad_units.ios.banner, 
      bannerAtTop: false, // Set to true, to put banner at top 
      overlap: false, // True to allow banner overlap webview 
      offsetTopBar: true, // True to avoid ios7 status bar overlap 
      isTesting: true, // receiving test to 
      Autoshow: true // auto show interstitial When loaded to 
 }; 
//prepare the banner view
 $cordovaAdMob.createBannerView(options, 
             function () {
                console.log (“success”); 
             }, 
             function (){
                console.log (“error”); 
             } 
 ); 
//show the banner
 $cordovaAdMob.showAd(true, 
             function () {
               console.log (“success”); 
             }, 
             function () {
               console.log (“error”); 
             } 
 ); 

options can be changed according to your needs
