            SetContentView(Resource.Layout.Main);
            TabHost host = new TabHost(this); // assuming inside Activity..
            TabHost.TabSpec spec;     // Resusable TabSpec for each tab   
            Intent intent;            // Reusable Intent for each tab   
            // Create an Intent to launch an Activity for the tab 
            intent = new Intent(this, typeof(MyHelloView));
            intent.AddFlags(ActivityFlags.NewTask);
            // Initialize a TabSpec for each tab and add it to the TabHost   
            spec = host.NewTabSpec("MyHelloView");
            spec.SetIndicator("Hello",
Resources.GetDrawable(Resource.Drawable.Icon));
