1. 准备工具类

import android.content.Context;
import android.content.Intent;public class RestartAPPTool {/*** 重启整个APP* @param context* @param Delayed 延迟多少毫秒*/public static void restartAPP(Context context, long Delayed){/**开启一个新的服务，用来重启本APP*/Intent intent1=new Intent(context,killSelfService.class);intent1.putExtra("PackageName",context.getPackageName());intent1.putExtra("Delayed",Delayed);context.startService(intent1);/**杀死整个进程**///android.os.Process.killProcess(android.os.Process.myPid());System.exit(0);}/***重启整个APP*/public static void restartAPP(Context context){restartAPP(context,2000);}
}

1. 准备Service

import android.app.Service;
import android.content.Intent;
import android.os.Handler;
import android.os.IBinder;
import android.util.Log;import com.king.armytv.MainActivity;public class killSelfService extends Service {/*** 关闭应用后多久重新启动*/private static long stopDelayed = 50;private Handler handler;private String PackageName;public killSelfService() {handler = new Handler();}@Overridepublic int onStartCommand(final Intent intent, int flags, int startId) {stopDelayed = intent.getLongExtra("Delayed", 50);Log.i("killSelfService", "stopDelayed:" + stopDelayed);PackageName = intent.getStringExtra("PackageName");handler.postDelayed(new Runnable() {@Overridepublic void run() {Intent LaunchIntent = new Intent(killSelfService.this, MainActivity.class);LaunchIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);startActivity(LaunchIntent);Log.i("killSelfService", "启动app");killSelfService.this.stopSelf();}}, stopDelayed);return super.onStartCommand(intent, flags, startId);}@Overridepublic IBinder onBind(Intent intent) {return null;}}

3 需要权限（华为手机测试需要这两个权限，少了启动不了）

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>

<uses-permission android:name="android.permission.SYSTEM_OVERLAY_WINDOW" />

4 AndroidManifest.xml 注册Service

<service

android:process=":restart"

android:name=".util.killSelfService" />

5 调用 RestartAPPTool.restartAPP(this);
