在下面例子中04Service中添加aidl包包里定义好接口 接口文件名后缀为.aidl

package com.example.aidl;

interface IRemoteService

{

void print(String msg);

String getName();

}

在04 client中也有这样一个包 这个包就成为一个接口   Service里实现接口  client中可以调用注意

Service中定义好service的action  client中绑定服务时用这个action

<service android:name=".RemoteService">

<intent-filter >

<action android:name="com.example.service04aidl.RemoteService"/>

</intent-filter>

</service>

绑定时用到

bindService(new Intent("com.example.service04aidl.RemoteService"),conn,BIND_AUTO_CREATE);

客户端每次绑定都会创建一个与客户端activity绑定的Service  activity销毁服务也会销毁
