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
