IPerson.aidl

package com.zzl.test;
interface IPerson { 
	void setName(String name);
	void setAge(int age);
	String display();
	
}

IPersonImpl

package com.zzl.test;

import android.os.RemoteException;

public class IPersonImpl extends IPerson.Stub{
	private String name;
	private int age;
	@Override
	public String display() throws RemoteException {
		return "name="+name+"age="+age;
	}

	@Override
	public void setAge(int age) throws RemoteException {
		this.age = age;
		
	}

	@Override
	public void setName(String name) throws RemoteException {
		this.name = name;
		
	}

}

MyRemoteService

package com.zzl.test;

import com.zzl.test.IPerson.Stub;

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

public class MyRemoteService extends Service{
	private Stub iPerson = new IPersonImpl();
	@Override
	public IBinder onBind(Intent intent) {
		// TODO Auto-generated method stub
		return iPerson;
	}

}

MainActivity

package com.zzl.test;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity {
    private Button btn_start;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        btn_start = (Button) findViewById(R.id.button1);
        
        btn_start.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View v) {
				Intent intent = new Intent(getApplicationContext(),MyRemoteService.class);
				startService(intent);
				btn_start.setText("服务器已启动");
			}
		});
    }
}

res/layout/main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
	xmlns:android="http://schemas.android.com/apk/res/android"
	android:orientation="vertical"
	android:layout_width="fill_parent"
	android:layout_height="fill_parent">
	<TextView
		android:layout_width="fill_parent"
		android:layout_height="wrap_content"
		android:text="@string/hello" />
	<Button
		android:text="启动服务器"
		android:id="@+id/button1"
		android:layout_width="wrap_content"
		android:layout_height="wrap_content" />
</LinearLayout>

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.zzl.test"
      android:versionCode="1"
      android:versionName="1.0">
    <uses-sdk android:minSdkVersion="10" />

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".MainActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        
       <service android:name="MyRemoteService"
				 android:process=":remote">
			<intent-filter>
        		<action android:name="com.zzl.test.MyRemoteService"></action>
    		</intent-filter>
		</service>

    </application>
</manifest>

注意：gen 下的 com.zzl.test下的文件时自动生成的。

这里的src下的com.zzl.test这个包是从服务器拷过来的。
MainActivity:

package com.zzl.client;
import com.zzl.test.IPerson;

import android.app.Activity;
import android.app.Service;
import android.content.ComponentName;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.Bundle;
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 {
	private IPerson iPerson;
    private Button btn_start;
    private ServiceConnection conn = new ServiceConnection(){

		@Override
		synchronized public void onServiceConnected(ComponentName name, IBinder service) {
			iPerson = IPerson.Stub.asInterface(service);
			if(iPerson!=null){
				try {
					//RPC方法调用
					iPerson.setName("无敌小鸡鸡");
					iPerson.setAge(6);
					String msg = iPerson.display();
					Toast.makeText(getApplicationContext(), msg, Toast.LENGTH_LONG).show();
				} catch (RemoteException e) {
					e.printStackTrace();
				}
			}
			
		}

		@Override
		public void onServiceDisconnected(ComponentName name) {
			// TODO Auto-generated method stub
			
		}};
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        btn_start = (Button) findViewById(R.id.button1);
        
        btn_start.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View v) {
				Intent intent = new Intent();
				//设置Intent 的Action属性
				intent.setAction("com.zzl.test.MyRemoteService");
				//绑定服务
				bindService(intent, conn, Service.BIND_AUTO_CREATE);
			}
		});
    }
}
