DependencyService 退出App

DependencyService 使用

1. 共享项目中创建接口

    using System.Collections.Generic;
    using System.Text;
   
    namespace OutAppDemo
    {
        public interface IAppManager
        {
            void CloseApp();
        }
    }
   

2. 在各个平台上分别实现此接口
   安卓平台

   
    using Android.OS;
    namespace OutAppDemo.Droid
    {
        public class AppManager : IAppManager
        {
            void IAppManager.CloseApp()
            {
                Process.KillProcess(Android.OS.Process.MyPid());
            }
        }
    }
   

   iOS

   using System;
   using System.Collections.Generic;
   using System.Linq;
   using System.Text;
   
   using Foundation;
   using UIKit;
   
   namespace OutAppDemo.iOS
   {
       public class AppManager : IAppManager
       {
           void IAppManager.CloseApp()
           {
               System.Threading.Thread.CurrentThread.Abort();
           }
       }
   }
   

   UWP

    省略
   

3. 注册各平台实现
   各平台接口实现类中，添加如下代码

    using Android.OS;
    using Xamarin.Forms; <--此处添加
   
    [assembly: Dependency(typeof(OutAppDemo.Droid.AppManager))] <--此处添加
    namespace OutAppDemo.Droid
    {
        public class AppManager : IAppManager
        {
            void IAppManager.CloseApp()
            {
                ......
            }
        }
    }
   

   安卓最终现实

   using System;
   using Android.OS;
   using Xamarin.Forms;
   
   [assembly: Dependency(typeof(OutAppDemo.Droid.AppManager))]
   namespace OutAppDemo.Droid
   {
      public class AppManager : IAppManager
      {
          void IAppManager.CloseApp()
          {
              Process.KillProcess(Android.OS.Process.MyPid());
          }
      }
   }   
   

4. 使用

   
    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;
    using Xamarin.Forms;
   
    namespace OutAppDemo
    {
        public partial class MainPage : ContentPage
        {
            public MainPage()
            {
                InitializeComponent();
            }
   
            private void Button_Clicked(object sender, EventArgs e) <--此处使用
            {
                //此处使用
                var manager = DependencyService.Get<IAppManager>();
                manager.CloseApp();
            }
        }
    }
