The code below works on Windows Phone but when running on Android I am getting the following exception : android.view.ViewRootImpl$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.
public ButtonLoggerPage()

};

tbSyncItemLbl = new Label { };
// Assemble the page.
this.Content = new StackLayout
{
Children = { button,new ScrollView { VerticalOptions = LayoutOptions.FillAndExpand,
BackgroundColor = Color.Gray,
Content = loggerLayout}
}
};
}
