如何将回调放入 Intent 中？
我想启动一个带有包含回调的意图的服务。我怎样才能做到这一点？我想使用startService(...)，而不是绑定机制。

我建议使用由服务发送的自定义广播。您可以在您的活动中注册该广播并收听该广播。这将是服务回调的标准解决方案。您不能将复杂的数据（如引用）放入您的意图中，只能将简单和原始的数据放入...

如何解释此演示文稿 然后（幻灯片 11，左下角的数字角落）？
在本例中，他们使用了服务助手。我认为他们用
startService启动服务器来象征服务应该保持唤醒状态。当绑定活动被销毁时，bindService将停止服务。无论如何，服务助手都会调用bindService，因为它显示10。活页夹回调。因此，最终帮助程序似乎是请求活动的绑定包装器，因此活动不必处理整个服务通信。这就是我的解释方式...
I would recommend to use a custom broadcast which will be sent by the service. You can register for that broadcast in your activity and catch that. That would be the standard solution for a service callback. You can't put complex data (like references) in your intent, simple and primitive data only...

How to interpret this presentation then (slide 11, number in bottom left corner)?
In this case they're using a service helper. I think they start the server with
startServiceto symbolize that the service should stay awake. AbindServicewould stop the service when the binding activity is destroyed. The service helper will callbindServiceanyway because it says10. Binder callback. So in the end the helper seems to be a bind wrapper for the requesting activity so the activities have not to deal with the whole service communication.That's the way I would interpret it...
