How to terminate a Xamarin application?

Question

How to terminate a Xamarin application from any of the activities?

I have tried both System.Environment.Exit(0) and System.Environment.Exit(1) as well as Finish() and killing all the activities.

It still opens one blank page with default activity name and a black screen.

Is there any specific solution for this?

Answer 1

If you are using Xamarin.Forms create a Dependency Service.

Interface

public interface ICloseApplication {     void closeApplication(); } 

Android : Using FinishAffinity() won't restart your activity. It will simply close the application.

public class CloseApplication : ICloseApplication {     public void closeApplication()     {         var activity = (Activity)Forms.Context;         activity.FinishAffinity();     } } 

IOS : As already suggested above.

public class CloseApplication : ICloseApplication {     public void closeApplication()     {         Thread.CurrentThread.Abort();     } } 

UWP

public class CloseApplication : ICloseApplication {     public void closeApplication()     {         Application.Current.Exit();     } } 

Usage in Xamarin Forms

var closer = DependencyService.Get<ICloseApplication>();     closer?.closeApplication();

A simple way to make it work cross platform is by this command:

System.Diagnostics.Process.GetCurrentProcess().CloseMainWindow(); 

Got it from this link.

EDIT: After using it for a while, I discovered that .CloseMainWindow() don't kill the application, only Closes it (well, thats obvious). If you want to terminate the app (kill), you shoud use the following:

System.Diagnostics.Process.GetCurrentProcess().Kill();
