title: Android admob can't see
body: <p>Admob code can't see on device.</p>
  
  <p>I followed the instructions here: <a href="http://www.admob.com/docs/AdMob_Android_SDK_Instructions.pdf" rel="nofollow">http://www.admob.com/docs/AdMob_Android_SDK_Instructions.pdf</a></p>
  
  <p>everything ok, but the 6. not clear for me</p>

    Step 6 </p>
    
    <p>When integrating AdMob ads into your application it is
    recommended to use test mode. In test mode test, ads are always
    returned. Test mode is enabled on a per-device basis. To enable test
    mode for a device, first request an ad, then look in LogCat for a line
    like the following: To get test ads on the emulator use
    AdManager.setTestDevices... Once you have the device ID you can enable
    test mode by calling AdManager.setTestDevices:</p>
  </blockquote>
  
  <pre><code>AdManager.setTestDevices( new String[] { AdManager.TEST_EMULATOR, //    Android emulator 
  "E83D20734F72FB3108F104ABC0FFC738", // My T-Mobile G1 Test Phone 
  } ); }
  </code></pre>
  
  <p>"</p>
  
  <p>What is that long number on the code? How do I get that number?</p>
  
  <p>In the oncreate method I put this code:</p>
  
  <pre><code>AdManager.setTestDevices(new String[] { AdManager.TEST_EMULATOR } );
  </code></pre>
  
  <p>(into the help activity, not into the main activity)</p>
