title: "Timed out waiting for ad response", when trying add admob into my application
body: <p>I am trying to add admob banner ads into my Android application, but after I followed all the instructions from Google, and did all the things, I found no ads displayed in application. When I checked LogCat in Eclipse, I found the error below. I am sure that I did edit all the files correctly, because when I tried to test the <a href="https://google-mobile-dev.googlecode.com/files/BannerXMLExample_Play_1.0.zip">sample file</a>. I got the same error message.</p>
  
  <blockquote>
    <p>01-04 18:43:52.448: W/Ads(5936): Timed out waiting for ad response.</p>
    
    <p>01-04 18:43:52.448: I/Ads(5936): Scheduling ad refresh 60000 milliseconds from now.</p>
    
    <p>01-04 18:43:52.458: W/Ads(5936): Failed to load ad: 2</p>

  <h2>Could anyone give me some advice please? Many Thanks!</h2>

  <p>I have added the adUnitId into my layout file:</p>
  
  <pre><code>        &lt;com.google.android.gms.ads.AdView 
          android:id="@+id/adView"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_below="@+id/label_status"
          android:layout_marginTop="30dp"
          ads:adUnitId="ca-app-pub-1183612543061916/9999996585"
          ads:adSize="BANNER" /&gt;
  </code></pre>
  
  <p>and also, I added test device in my code:</p>
  
  <pre><code>        adView = (AdView) findViewById(R.id.adView);
          AdRequest adRequest = new AdRequest.Builder()
          .addTestDevice("F84FF00544A8000C28E55068B835F2BD")
          .build();
  
          adView.loadAd(adRequest);
  </code></pre>
