Android绑定(bind)服务和AIDL服务

Question

我读到了bound service和 AIDL based service Android 开发者指南

两者似乎都允许其他组件绑定(bind)并执行进程间通信

Bound service allows components (such as activities) to bind to the service, send requests, receive responses, and even perform interprocess communication (IPC).

AIDL (Android Interface Definition Language) is similar to other IDLs you might have worked with. It allows you to define the programming interface that both the client and service agree upon in order to communicate with each other using interprocess communication (IPC).

那么有什么区别呢？

Answer 1

AIDL 只是与绑定(bind)服务通信的一种方式。不存在“基于 AIDL 的服务”这样的东西，它只是一个绑定(bind)服务，返回一个基于 AIDL 接口(interface)生成的 Binder。
