title: Admob works doesn't gives me money
body: <p>I added admob to my android app, the banners are sometimes shown sometimes are not but that is okey. The thing that is weird for me is that when I logging to admob.com page and I check my account I see that the field for requests is increasing and in the moment is 30, the eCPM is 0$ and the RPM is 0$, also the fill rate field is something like 5%.</p>
  
  <pre><code>Requests       30
  eCPM           0$
  Fill Rate      5%
  RPM            0$
  </code></pre>
  
  <p>I have many questions, but my main question is why I do not get any money ?</p>
  
  <p>I guess I didn't done something in my code so I do not earn money...
  I do not know what I am missing. I take the publisher ID from the admob, and I putted in the code to the right place, and obviously it works cause the requests are increasing. But why I do not get any money ? Did I need to do something else ? some other permission or something ?</p>
  
  <p>I really do not have experience with admob, maybe this is not the place to ask questions but still I asked cause I think the problem is in my code , I think that I am missing something.</p>
  
  <p>NOTE:
  my app is not published in the market, is that the problem ? Is it requirement app to be published to the marked so the admob can works ? </p>
