Hello,​

Welcome to our Microsoft Q&A platform!

i get this error "PushAsync is not supported globally on Android, please use a NavigationPage."

This is because Navigation.PushAsync method requires to be used in the navigation stack. To avoid this, try using the model page to perform navigation:

   Navigation.PushModalAsync(new NavigationPage(new Page1()));  

Or add the tabbedPage to the navigation stack and set the navigationbar invisible. Then it's available to call Navigation.PushAsync to perform navigation.

   public partial class App : Application  
   {  
       public App()  
       {  
           InitializeComponent();  
     
           MainPage = new NavigationPage( new TabbedPage1());  
       }  
   }  
     
   public partial class TabbedPage1 : TabbedPage  
   {  
       public TabbedPage1()  
       {  
           InitializeComponent();  
     
           NavigationPage.SetHasNavigationBar(this, false);  
       }  
   }  
     
    public partial class listofinterest : ContentPage  
    {  
        private async void Add(object sender, EventArgs e)  
        {  
            await Navigation.PushAsync(new NavigationPage(new MainPage()));  
        }  
    }
