title: How do I use Admob Live ads on my app?
body: <p>I have an app ready to be published on store on which I've used Banner Ads from Admob and I've been using a Test ID as of late. I have my Admob ID with me, but can I update the test ID with the real ID and run it on the emulator once for updating the code? As far as I know the changes aren't reflected back in the .apk file until the project isn't run again on the emulator. </p>
  
  <p>I fear since this is a live ad, I cannot use it for development purpose. Also, what changes would I need to make in an order to get the app working with live ads? Any help will be highly appreciated.</p>
