            //string myVersionName = Application.Context.ApplicationContext.PackageManager.GetPackageInfo(Application.Context.ApplicationContext.PackageName, 0).VersionName;

            this.DisplayAlert(title: "App Details", message: "Note myVersionName='" + myVersionName + "' here.", cancel: "Ok");
