title: AFMA_ReceiveMessage is not defined
body: <p>I am integrating AdMob in my android app. The code for the add part is pretty simple and almost straight from Google Developer's guide. I am trying to implement Interstitials. The ads are showing fine but I am getting this in stackTrace in red:</p>
  
  <blockquote>
    <p>E/Ads(21443): JS: Uncaught ReferenceError: AFMA_ReceiveMessage is not defined (null:1)</p>
  </blockquote>
  
  <p>Can anyone tell me what it means? Is it ok to release the app with this error as it doesn't crash the app?</p>
  
  <p>EDIT: I just noticed that this error is being received for a specific ad and not for the other(just getting two ads in my country for now). So maybe it's just something missing from Publisher end.</p>
