android - 当所有活动解除绑定时，是否会破坏有界服务？

Question

我在 android 有界服务的 onStartCommand() 中创建一个单独的线程，并使用 Runnable 的 Run() 中的条件检查来运行它，例如，当（条件）时，有一个活动正在使用这个有界服务，然后解除它的绑定。我读到有一条规则，如果没有绑定的活动，有界服务会自动销毁。我是否需要在 unbind 方法中翻转我的条件，否则服务将如何知道它现在必须终止？如果是，那么它由我的代码控制，而不是由 Android 本身控制

import android.app.Service;
import android.content.Intent;
import android.os.Binder;

public class ServiceDemo extends Service {

    private static final String TAG = "ServiceDemo";

    private boolean isRunning = false;
    private boolean isBound = false;
    private int counter = 0;
    private static final int MIN = 0;
    private static final int MAX = 100;

    IBinder myServiceBinder = new MyServiceBinder();

    public class MyServiceBinder extends Binder {
        public ServiceDemo getServiceInstance(){
            return ServiceDemo.this;
        }
    }

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        isBound = true;
        return myServiceBinder;
    }

    @Override

        Log.i(TAG, "onStartCommand executed in Thread : "+Thread.currentThread().getId());

                   counter++;
               }

        isBound = false;
        return super.onUnbind(intent);

    @Override
