android aidl通信

Web端
定义接口MyAdil.aidl

package com.service_aidl_web;

interface MyAidl{

	int count(int num1,int num2);
	
	String say();

}

MyService.java

package com.service_aidl_web.service;

import com.service_aidl_web.MyAidl;

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

public class MyService extends Service {
	
	@Override
	public IBinder onBind(Intent intent) {
		// TODO Auto-generated method stub
		return new MyBinder();
	}
	private class MyBinder extends MyAidl.Stub{

		@Override
		public int count(int num1, int num2) throws RemoteException {
			// TODO Auto-generated method stub
			return num1+num2;
		}

		@Override
		public String say() throws RemoteException {
			// TODO Auto-generated method stub
			return "您好";
		}
		
	}
}

复制gen下的com.service_aidl_web/MyAidl.java连包一起复制到客户端src下


Client端调用
MainActivity.java

package com.service_aidl_Client;


import com.service_aidl_web.MyAidl;

import android.app.Activity;
import android.content.ComponentName;
import android.content.Context;

import android.os.IBinder;
import android.os.RemoteException;

import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;



public class MainActivity extends Activity implements OnClickListener {

	private ServiceConnection connection = new ServiceConnection() {

	};

	@Override
