title: Xamarin Listview data loading is slow on the Android side
body: <p>For example, when I want to open the city list, when I tap on the menu, the other page is loaded with the listview web service. On the ios side, the transition to the next page is fast. There is a slight wait on the Android side. What is the reason?</p>

  <pre><code>Device.BeginInvokeOnMainThread(() =&gt;
          {
              switch (Device.RuntimePlatform)

                      LoadItems();
                      activity.IsVisible = false;
