AIDL（二）案例解析

1.目录结构 app服务端 aidlclient客户端

一.服务端代码

2.1 IMyAidlInterface.aidl

// IMyAidlInterface.aidl

package com.example.zb.adiltestdemo;

interface IMyAidlInterface {

//求和

int add(int num1,int num2);

}

2.2服务 MyService

public class MyService extends Service {

public MyService() {

}

/**

* 当客户端绑定到该服务的时候，会执行该方法

* @param intent

* @return

@Override

public IBinder onBind(Intent intent) {

return mIBinder;

}

private IBinder mIBinder=new IMyAidlInterface.Stub() {

@Override

public int add(int num1, int num2) throws RemoteException {

Log.i("TAG","收到了远程请求，输入的参数是"+num1+"和"+num2);

return num1+num2;

}

};

}

二。客户端代码

1.IMyAidlInterface.aidl

// IMyAidlInterface.aidl

package com.example.zb.adiltestdemo;

interface IMyAidlInterface {

//求和

int add(int num1,int num2);

}

注意：IMyAidlInterface代码跟服务端一致，包名必须也一致。
