title: why google Admob ads not showing up
body: <p>I just create an android app and wants to integrate ads from my google AdMob account. but Ads do not show up.<br>
  But when I test my app from the developer's guidance as they provide sample id's for banner and interstitial ads and also for app id the app work fine but as soon as I put banner id, interstitial ads id and app id from my Admob account then the problem occurred. I did not publish my app till now to play store and I just created my AdMob account does it take time to verify or any suggestion why ads not showing up.</p>
