title: Xamarin.Forms Maps crashing app
body: <p>I'm having a hard time trying to show a map on my Xamarin Forms app. This is the error I get everytime I open the page with the map:</p>

  <p>This is the code for creating the page:</p>
  
  <pre><code>var topLayout = new StackLayout
  {
      Children =
      {
          new Map(MapSpan.FromCenterAndRadius(new Position(37,-122), Distance.FromMiles(0.3)))
          {
              IsShowingUser = true,
              HeightRequest = 100,
              VerticalOptions = LayoutOptions.FillAndExpand
          }
      }
  };
  
  var bottomLayout = new StackLayout { Children = { ... }  }; //shortened for readability
  
  Content = new StackLayout
  {
      Children = { topLayout, bottomLayout }
  };
  </code></pre>
  
  <p>I'm saying the problem is the map, because if I change the "new Map" line for a Label, for instance, it works.</p>
  
  <p>I'm instantiating the Maps FW as said here: <a href="http://developer.xamarin.com/guides/cross-platform/xamarin-forms/working-with/maps/" rel="nofollow">http://developer.xamarin.com/guides/cross-platform/xamarin-forms/working-with/maps/</a></p>
  
  <pre><code>protected override void OnCreate(Bundle bundle)
  {
      base.OnCreate(bundle);
  
      global::Xamarin.Forms.Forms.Init(this, bundle);
      Xamarin.FormsMaps.Init(this, bundle);
      LoadApplication(new FullHelp.App());
  }
  </code></pre>
