title: Xamarin: open Google Maps App from a Android WebView App
body: <p>I have created a WebView App with VS2015 / Xamarin.
  The WebView loads an external webiste (the pages are not included in the APP).
  One of the website pages contains an html link of this kind:</p>
  
  <pre><code>&lt;a href="geo:42.374260,-71.120824"&gt;
  </code></pre>
  
  <p>I would like to make sure Android opens Google Maps App when a user clicks on the link.
  I have made use of ShouldOverrideUrlLoading in this way:</p>
  
  <pre><code>public class WebClient : WebViewClient
          {
              public override bool ShouldOverrideUrlLoading(WebView view, string url)
              {
  
                  //Click on a georeferenced link
                  if (url.IndexOf("geo:")&gt;-1)
                  {
                      var geoUri = Android.Net.Uri.Parse("geo:42.374260,-71.120824");
                      var mapIntent = new Intent(Intent.ActionView, geoUri);
                      StartActivity(mapIntent);
                      return true;
                  }
  
                  //Click on a generic link
                  view.LoadUrl(url);
                  return true;
              }
          }
  </code></pre>
  
  <p>Now, problem is, the StartActivity line returns an error: <em>An object reference is required for the non-static field, method, or property 'ContextWrapper.StartActivity(Intent)'</em></p>
  
  <p>Could you suggest which is the right syntax I should use to avoid this error ? </p>
