本文介绍了一个使用AIDL（Android接口定义语言）实现的服务绑定示例，详细展示了如何创建和使用AIDL文件，以及如何在客户端和服务端进行交互。

绑定service需要在上一讲中，新创建一个AIDL。

// AppServiceRemoteBinder.aidl
package com.example.yabushan.aidsservice;

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

interface AppServiceRemoteBinder {
    /**
     * Demonstrates some basic types that you can use as parameters
     * and return values in AIDL.
     */
    void basicTypes(int anInt, long aLong, boolean aBoolean, float aFloat,
            double aDouble, String aString);
}

　　在服务类中的onBind方法返回这个新创建的AIDL(可能需要rubuild project)

package com.example.yabushan.aidsservice;

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

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

    @Override
    public IBinder onBind(Intent intent) {
        return  new AppServiceRemoteBinder.Stub(){

            @Override
            public void basicTypes(int anInt, long aLong, boolean aBoolean, float aFloat, double aDouble, String aString) throws RemoteException {

            }
        };
    }

    @Override
    public void onCreate() {
        super.onCreate();
        System.out.println("service on start");
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        System.out.println("service deastroy");
    }
}

package com.example.yabushan.anotherapp;

import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.IBinder;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;

public class MainActivity extends AppCompatActivity implements View.OnClickListener, ServiceConnection {

    private Intent serviceIntent;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        serviceIntent=new Intent();
        serviceIntent.setComponent(new ComponentName("com.example.yabushan.aidsservice","com.example.yabushan.aidsservice.AppService"));
        findViewById(R.id.startService).setOnClickListener(this);
        findViewById(R.id.stopService).setOnClickListener(this);
        findViewById(R.id.BindService).setOnClickListener(this);
        findViewById(R.id.unBindService).setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()){
            case R.id.startService:

                startService(serviceIntent);
                break;
            case R.id.stopService:
                stopService(serviceIntent);
                break;
            case R.id.BindService:

                bindService(serviceIntent,this, Context.BIND_AUTO_CREATE);
                break;
            case R.id.unBindService:
                unbindService(this);
                break;

        }

    }

    @Override
    public void onServiceConnected(ComponentName name, IBinder service) {
        System.out.println("bind service");
        System.out.println(service);
    }

    @Override
    public void onServiceDisconnected(ComponentName name) {

    }
}
