title: Flurry:Ad server responded but sent no ad units
body: <p>I am Using Flurry ads in my android  Application.
  I have created one AdSpace on flurry server and accessing it in my application.
  And I don’t have any Campaign as I want ads only from AppCircle. However, I am able to get test ads, But when I trying to get actual ads using flurry AppCircle(by setting <code>enableTeastAds(false)</code>) it shows following error,</p>
  
  <pre><code>Ad server responded but sent no ad units.
  </code></pre>
  
  <p>How can i solve it? do i need to configure Campaign to receive ads from flurry Appcircle?</p>
  
  <p>this is my logcat output.</p>
