initiAdMob();
showAdMobInterestitial();
showAdMobBanner();
};

document.addEventListener("deviceready",onDeviceReady,false);

function initAdMob(){
if(window.plugins && window.plugins.AdMob){
var admob_key_banner = "xxxxxxxxxxxx";
var admob_key_interstitial = "xxxxxxxx";
window.plugins.AdMob.setOptions({
publisherId: admob_key_banner,
bannerAtTop: true, //set to true put banner at top
overlap: false, //set to true, to allow banner overlap webview
offsetTopBar: true,//set to true to avoid ios? stutus bar overlap
intertitialAdid: admob_key_intertitial,
autoShow: true, //autoshouw intertitial ad
isTesting: false // receiving test ad
});
}else{
    
    alert("AdMob plugins not ready");
    
}
}
function showAdMobBanner(){
    
    window.plugins.AdMob.createBannerView();
    
}
function showAdMobInterestitial(){
    
    window.plugins.AdMob.createInterestitialView();
}
</script>
