在活动和服务中注册接收者的缺点?

• 活动可以查询服务以查看是否正在运行
• 活动可以查询服务中的变量值

• 服务可以发送对活动的响应

• 服务可以在活动调用时响应活动

LocalBroadcastManager 有点像:

public class MyActivity extents Activity{

   private void receiver = new BroadcastReceiver(){
      onReceive(){
        //Handle Message from Service
      }
  }

  onResume -> LocalBroadcastManager.registerReceiver(receiver);
  onPause  -> LocalBroadcastManager.unregisterReceiver(); 
} 

public class MyService extents Service{

   private void receiver = new BroadcastReceiver(){
      onReceive(){
        //Handle Message from Activity
      }
  }

  onStart-> LocalBroadcastManager.registerReceiver(receiver);
  onDestroy-> LocalBroadcastManager.unregisterReceiver(); 
} 

这将允许避免应用程序组件之间的绑定或其他通信方法,但同时允许发送意图和侦听观察者。这种方法有缺点吗?
