title: Empty space after AdMob disappear
body: <p>I have layout structure:</p>
  <pre><code>&lt;LinearLayout
    xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
    android:layout_width=&quot;fill_parent&quot;
    android:layout_height=&quot;fill_parent&quot;
    android:orientation=&quot;vertical&quot; &gt;
    &lt;com.google.ads.AdView 
     android:layout_width=&quot;fill_parent&quot;
     android:layout_height=&quot;wrap_content&quot;
     ads:adSize=&quot;BANNER&quot;
    /&gt;
      
    &lt;LinearLayout style=&quot;@style/TitleBar&quot;
     android:layout_width=&quot;fill_parent&quot;
     android:layout_height=&quot;45dip&quot;
      // title bar
    &lt;/LinearLayout&gt;
    
  &lt;RelativeLayout
    android:layout_width=&quot;fill_parent&quot;
    android:layout_height=&quot;fill_parent&quot;
    android:orientation=&quot;vertical&quot;
    // main layout with all needed elements and background!&quot; &gt;
    
  &lt;/RelativeLayout&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
  <p>Everything look fine, until my AdMob disappered. Then I can see empty black region with admob size.</p>
  <p>UPDATE: my screen shot:
