android 前台service

android studio启动了一个前台服务，但是在手机上查看正在运行的服务只显示1个进程和0个服务，我在服务中开启了线程循环打印能够打印，但是我不知道为什么会显示0个服务，正常难道不是应该显示1个进程和1个服务吗，这是为什么

下边是代码


Intent intent = new Intent(this, ForegroundSrv.class);
                if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O){
                    this.startForegroundService(intent);
                }else {
                    this.startService(intent);
                }
