Navigation.Popasync() does not work when used as an option to exit the application

Question

I have a one-screen app, a "Contentpage".

I can’t get out of the app with "Popasync()".

I’m debugging on a Samsung J6 device.

// página instanciada
MainPage = new NavigationPage(new Inicio());

// opção usada para sair do aplicativo
private async void Sair(object sender, EventArgs e)
{
  await Navigation.PopAsync();
}

Answer 1

Hello @Domingos Neto,

As has already been said, Navigation.PopAsync() is a method to pop windows in your application, since there is only one window such method will not be useful.

Regarding your "programmatically close app" approach, what I can say is that this is not an approach recommended by stores primarily by Apple (more details through the link), because such behavior can be seen by the user as a crash (unexpected failure), so your app may even be rejected during the posting attempt.

I have already gone through this, and explained to my superiors what I said above and such "functionality" was disregarded.

Answer 2

I advise not to use internal methods to close the application, Apple will bar the application and have a chance google do the same.

Answer 3

Hello. I use the code below to exit and close an App.

// opção usada para sair do aplicativo
private async void Sair(object sender, EventArgs e)
{
  System.Diagnostics.Process.GetCurrentProcess().Kill();
}
