title: MapView in a Fragment (Honeycomb)
body: <p>now that the final SDK is out with google apis - what is the best way to create a Fragment with a MapView? MapView needs a MapActivity to work right.</p>
  
  <p>Having the Activity managing the Fragments inherit from MapActivity (bad solution because it goes against the idea that Fragments are self contained) and use a regular xml based layout does not work. I get a NullPointerException in MapActivity.setupMapView():</p>

  <p>My second idea was to create the MapView programmatically and pass the associated activity (via getActivity()) as Context to the MapView constructor. Does not work:</p>

  <p>Really there should be something like MapFragment that takes care of the background threads MapView needs I guess... So what is the current best practice to do this?</p>
