Monodroid Javascript Call-back

Question

I\'m trying to use monodroid with webkit to create an app. I am having a problem with letting the html page call a javascript method, which would be an interface to a method

Answer 1

I found that calling LoadData after AddJavascriptInterface was necessary. Also, with this change, assigning a WebChromeClient was not needed. For example, the modified version below runs fine:

public class Activity1 : Activity
{
    const string html = @"
    
    
    
This is a paragraph.
    Click Me!
    
    ";

    protected override void OnCreate (Bundle bundle)
    {
        base.OnCreate (bundle);

        SetContentView (Resource.Layout.Main);

        WebView view = FindViewById (Resource.Id.web);
        view.Settings.JavaScriptEnabled = true;

        view.AddJavascriptInterface (new Foo (this), "Foo");
        view.LoadData (html, "text/html", null);
    }

    class Foo : Java.Lang.Object, Java.Lang.IRunnable
    {
        Context context;

        public Foo (Context context)
        {
            this.context = context;
        }

        public void Run ()
        {
            Toast.MakeText (context, "This is a Toast from C#!", ToastLength.Short).Show ();
        }
    }
}
