自定义的操作
在 AIDL 当中, 可以传递自定义的对象, 例如自己定义的 Person 类的对象, 也是可以传递的。 但是对于自定义的 Person 类, 需要做出相关的设置: （1）需要实现接口 android.os.Parcelable A. 重写了方法 describeContents B. 构造方法 Person C. 写数据的方法 writeToParcel D. 内部类的对象 CREATOR （2）需要定义读数据的方法 readFromParcel
关于自定义对象的操作
1. IN 输入 2. OUT 输出 3. INOUT 输入输出
加法的操作，关于服务端的处理 hello.svip.server
加法的操作，关于客户端的处理 hello.svip.client
关于 IN 的操作，关于服务端的展示数据 hello.svip.server
关于IN的操作，关于客户端的展示数据 hello.svip.client
关于 OUT 的操作，关于服务端的展示数据 hello.svip.server
关于 OUT 的操作，关于客户端的展示数据 hello.svip.client
关于 INOUT 的操作，关于服务端的展示数据 hello.svip.server
关于 INOUT 的操作，关于客户端的展示数据 hello.svip.client

1. 客户端和服务端, 当中都需要拥有 HelloAIDL.aidl 文件 和 Person.aidl 文件 2. 客户端和服务端, 当中都需要拥有 Perosn.java 文件, 另外他们的是包名称都是 hello.svip.server.Person 文件
关于 Person.java 类的实现当中： 1、需要实现接口 android.os.Parcelable 2、除了自己的 getter 和 setter 方法外, 还需要有以下五部分内容: A. describeContents B. Person 新增构造方法 C. writeToParcel 写数据的方法 D. readFromParcel 读数据的方法 E. CREATOR 内部类的对象
