  I did some JavascriptInterfacing a while back, where I had to make a dummy .java file with the methods and signatures needed for the interfaces and used JNI to make a wrapper for C#. You can look in https://github.com/Cheesebaron/MonoDroid.WAToolkit/tree/master/MonoDroid.WAToolkit.Library/Login for a sample.

  public class WebViewActivity {

  protected override void OnCreate (Bundle savedInstanceState) {
      var _RL = new RelativeLayout (Activity);
      RelativeLayout.LayoutParams _params = new RelativeLayout.LayoutParams (RelativeLayout.LayoutParams.FillParent, RelativeLayout.LayoutParams.FillParent);
  
      WebView _WV = new WebView (Activity);
      _WV.Id = 0X10000;
      _WV.LayoutParameters = _params;
      _WV.Settings.JavaScriptEnabled = true;
      _WV.AddJavascriptInterface (new JsObject (Activity), "JsObject");
      _RL.AddView (_WV);
      _WV.LoadData ("", "text/html", null); //Must !! Load anything before target url
      _WV.LoadUrl (YourUrl);
      _WV.LoadUrl ("javascript:document.write(JsObject.GetString())");
  }
  

  }

  public class JsObject : Java.Lang.Object {

  Context context;
  
  public JsObject (Context context) {
      this.context = context;
  }
  
  public JsObject (IntPtr handle, JniHandleOwnership transfer) : base (handle, transfer) {
  }
  
  [Export ("GetString")]
  [JavascriptInterface]
  public string GetString () {
      return "Ooooops!!";
  }
  

  }

  It's work for API Level 17 & 18
