Service进程间

服务器

创建一个Service

package com.example.aidl_server;

import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.os.RemoteException;


public class AudkService extends Service {
    public AudkService() {
    }

    //服务器 提供a+b的运算，并返回运算的值
    IBinder iBinder = new IMyAidlInterface.Stub() {
        @Override
        public int add(int a, int b) throws RemoteException {
            return a+b;
        }
    };



    @Override
    public IBinder onBind(Intent intent) {
        return iBinder;
    }
}

创建一个文件夹aidl中右键创建IMyAidlInterface

// IMyAidlInterface.aidl
package com.example.aidl_server;

// Declare any non-default types here with import statements

interface IMyAidlInterface {
    int add (int a ,int b);
}
