关于Service引起ANR的有关问题

关于Service引起ANR的问题
这是我自己写的服务，用来启动一个广播接收器

MyService.java

Java code

package zzx.Android;

import android.app.Activity;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;

public class MyService extends Service{

    private ShutDownReceiver sr = null;
    
    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        
        

        MyService.this.sr = new ShutDownReceiver();

                
        return Service.START_CONTINUATION_MASK; 
        
    }

    @Override
    public IBinder onBind(Intent intent) {
        // TODO Auto-generated method stub
        return null;
    }
    
}

log：

  为什么这个服务总会引起ANR呢？是因为Service中不能执行耗时操作，要在新的线程中执行吗？
可是我只是启动了一个广播接收器，不算耗时操作吧？

  初学Android，麻烦各位高手帮忙！

可以使用IntentService
