前面两片文章讲解了通过AIDL和Messenger两种方式实现Android IPC.而本文所讲的并不是第三种IPC方式,而是对前面两种方式进行封装,这样我们就不用直接把Aidl文件,java文件拷贝到客户端了,而是为客户端提供一个aar(Anroid Archive)包.通过这个aar包对AIDL或者Messenger进行封装,最终客户端就可以像调用一般的java类一样,而不用处理通信方面的内容.(实际上书中说是要打包成jar包,但是在新建的Java Library Module中,我没能成功…

Messenger类实际是对Aidl方式的一层封装.本文只是对如何在Service中使用Messenger类实现与客户端的通信进行讲解,对Messenger的底层不做说明.阅读Android Programming: Pushing the Limits -- Chapter 7:Android IPC -- AIDL了解如何使用Aidl的方式实现服务端与客户端的通信. 在Service中使用Messenger,大部分代码还是跟Android的消息机制打交道,具体一点就是跟Handler,Mes…

实现一个泛型的双端队列和随机化队列,用数组和链表的方式实现基本数据结构,主要介绍了泛型和迭代器. Dequeue. 实现一个双端队列,它是栈和队列的升级版,支持首尾两端的插入和删除.Deque的API如下 public class Deque<Item> implements Iterable<Item> { public Deque() // construct an empty deque public boolean isEmpty() // is the deque emp…
