title: Interstatial Admob using PhoneGap not working
body: <p>I'm trying to display interstitial Ad in my PhoneGap app but it's not working; it's not displaying the ad at all. I followed the instructions <a href="https://developers.google.com/mobile-ads-sdk/docs/admob/android/interstitial" rel="nofollow">here</a>.</p>
  
  <p>Apart from trying to make it work, what I also need to do is to show the interstitial at a particular time (probably when the game is over) but I dont know how to refer to the Java code from JavaScript code to show the loaded interstitial ad.</p>
  
  <p>Please help.</p>
