title: How to implement Admob AdView in Android app
body: <p>I want to use Admob in my app. I've downloaded the SDK and followed the steps. Sometimes, I get an ad in return, but most of the time, I get an entry in LogCat that says "Server did not find any ads" or something to that effect. Test mode is enabled, says the Admob site. I think I might be doing something wrong. Where can I get a step-by-step guide to insert admob ads in Android apps? The Admob developer site is rather lacking.</p>
  
  <p>Also, let's assume that everything's gone well and that I'd now like to deploy the app. How do I turn off test mode for Admob ads?</p>
  
  <p>Thank you.</p>
