title: Google Maps V2 setLocationSource removes blue MyLocation icon
body: <p>I'm working on an indoor GPS application and I have my own location provider that will give me lat and long.  I have google maps v2 working with my location provider by using</p>
  
  <pre><code>mMap.setMyLocationEnabled(true);
  mMap.setLocationSource(myLocationProvider);
  </code></pre>
  
  <p>My problem is as I set the location source to my custom provider, the little blue icon that displays onscreen location no longer functions.  Is this expected?  Shouldn't google maps just use the lat/long to display the current location, no matter where it comes from?</p>
