title: Android: admob only works in emulator
body: <p>I set up admob for one of my apps, and it only recieves ads on my emulator, never on my phone.</p>
  
  <p>Set it up the xml way (<a href="http://code.google.com/mobile/ads/docs/android/banner_xml.html" rel="nofollow">http://code.google.com/mobile/ads/docs/android/banner_xml.html</a>), and everything shows up fine when i run the emulator, but as soon as i try it with my phone, it never recieves an ad.</p>
  
  <p>Weird thing is, my admob account has like 1000 request and a 60% fill rate. I can just never see them I guess.</p>
  
  <p>Why do you think it doesnt work on my phone? Thanks</p>
  
  <p>xml to create it:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:ads="http://schemas.android.com/apk/res/com.EricLunty.i90xLITE"
  android:layout_width="fill_parent" android:layout_height="wrap_content"
  android:orientation="vertical"&gt;
  &lt;com.google.ads.AdView android:id="@+id/adView"
      ads:adUnitId="a14dbddfe120711" ads:adSize="BANNER" android:layout_height="50dip" android:layout_width="320dip"/&gt;
  &lt;ListView android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@+id/mainList"&gt;&lt;/ListView&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>attrs xml:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;resources&gt;
  &lt;declare-styleable name="com.google.ads.AdView"&gt;
      &lt;attr name="adSize"&gt;
          &lt;enum name="BANNER" value="1" /&gt;
          &lt;enum name="IAB_MRECT" value="2" /&gt;
          &lt;enum name="IAB_BANNER" value="3" /&gt;
          &lt;enum name="IAB_LEADERBOARD" value="4" /&gt;
      &lt;/attr&gt;
      &lt;attr name="adUnitId" format="string" /&gt;
  &lt;/declare-styleable&gt;
  &lt;/resources&gt;
  </code></pre>
  
  <p>calls this during oncreate()</p>
  
  <pre><code>adView = (AdView) findViewById(R.id.adView);
  adView.loadAd(new AdRequest());
  </code></pre>
