title: Geolocation cannot be load on webview
body: <p>I want to load Geolocation into my webview on android 2.1. The geolocation works well on my browser, but it does fail on webview.</p>
  
  <pre><code>public class WebPageLoader extends Activity implements GeolocationPermissions.Callback{
  
      WebView webview;
      String geoWebsiteURL = "http://hngu.naf.cs.hut.fi/current_location.html";
      public WebPageLoader() {
      }
  
      /**
       * Called with the activity is first created.
       */
      @Override
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
  
          setContentView(R.layout.main);
  
          webview = (WebView) findViewById(R.id.webview);
          webview.getSettings().setJavaScriptEnabled(true);
          webview.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
          webview.getSettings().setGeolocationEnabled(true);  //seems like if i set this, the webview should prompt when I call navigator.geolocation.getCurrentPosition
          GeoClient geo = new GeoClient();
          webview.setWebChromeClient(geo);        
          String origin = ""; //how to get origin in correct format?
          geo.onGeolocationPermissionsShowPrompt(origin, this);  //obviously not how this is meant to be used but expected usage not documented
          webview.loadUrl(geoWebsiteURL);        
  
      }
  
      public void invoke(String origin, boolean allow, boolean remember) {
  
      }
  
      final class GeoClient extends WebChromeClient {
  
      @Override
      public void onGeolocationPermissionsShowPrompt(String origin,
      Callback callback) {
      // TODO Auto-generated method stub
      super.onGeolocationPermissionsShowPrompt(origin, callback);
      callback.invoke(origin, true, false);
      }
