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);
    }
}

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();
    }

    @Override
    public 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() {
            @Override
            public 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);
    }


    @Override
    public 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);文章来源地址https://www.toymoban.com/news/detail-568140.html
