using System.Text;
using COCApp;

using Xamarin.Forms;

namespace COCApp

    {

            MainPage = new NavigationPage(new MainPage());
        }

        protected override void OnStart()
        {
            // Handle when your app starts
        }

        protected override void OnSleep()
        {
            // Handle when your app sleeps …
