title: map in webview add marker
body: <p>I want to add a map in my android, I can't extends MapActivity because the map is in a tab ant it extends Fragment.</p>
  
  <p>So I'm using a WebView, I followed this code:</p>
  
  <p><a href="https://developers.google.com/maps/articles/android_v3" rel="nofollow">https://developers.google.com/maps/articles/android_v3</a></p>
  
  <p>the problem is when I try to add a marker, in the html file I have:</p>
  
  <pre><code>  function createMarker(lat, lng){
  var latlng = new google.maps.LatLng(lat, lng);           
  var marker = new google.maps.Marker({
      position: latlng,
      map: map
  });
  
  return marker
  </code></pre>
  
  <p>I guess the problem is "map" because I don't know how to access to this.</p>
