title: Problem inflating MapView
body: <p>I'm going through the documentation at <a href="http://developer.android.com/guide/tutorials/views/hello-mapview.html" rel="nofollow">Hello, MapView</a> to add a MapView to my Activity.</p>
  
  <p>When I launch my Activity, I get an inflation error on the MapView.</p>
  
  <p>Here is the MapView in my layout xml:</p>
  
  <pre><code>&lt;com.google.android.maps.MapView
      android:id="@+id/mymap"
      android:layout_width="fill_parent"
      android:layout_height="200dip"
      android:clickable="true"
      android:apiKey="withheld"
      /&gt;
  </code></pre>
  
  <p>Here is the code in my MapActivity (the class is named ActivityDetails and extends MapActivity) class:</p>
  
  <pre><code>    MapView mMap;
      mMap = (MapView) findViewById(R.id.mymap);
      mMap.setBuiltInZoomControls(true);
  </code></pre>
  
  <p>Here is the error:</p>

  <p>As far as I can tell, I've done everything correct as described in the documentation. I've set my build target to Google APIs, I've added the uses-library tag to my Manifest, I'm running in an emulator with the Google API target...</p>
