title: AdMob Android Integration
body: <p>Issue #1: In the tutorials, that I've looked at, a lot of folks place this line of code:</p>
  
  <pre><code>AdManager.setTestDevices( new String[] {AdManager.TEST_EMULATOR});
  </code></pre>
  
  <p>into the onCreate override of the activity.  And sure enough, the test ad shows up.</p>
  
  <p>Am I supposed to leave this line when I actually submit my app to the App Store?
  Won't it show a test ad when the users actually use my app?</p>
  
  <p>Issue #2: I've also seen some examples where the code manually requests the ad:</p>
  
  <pre><code>AdView adView = (AdView) findViewById(R.id.ad);
  adView.requestFreshAd();
  </code></pre>
  
  <p>Do I actually need these lines?</p>
  
  <p>Unfortunately I don't have a device handy and can't test any of these assumptions?</p>
