本文介绍了一个应用程序(app1)如何通过定义服务并暴露接口，使得另一个应用程序(app2)能够调用该服务中的方法。具体包括app1中服务的定义、接口声明及其实现，以及app2中如何绑定服务并调用其方法。

app2调用app1的服务里面的方法

app1:

清单文件

        <service android:name="com.ldw.alipay.payService">
            <intent-filter >
                <action android:name="com.ldw.pay"/>
            </intent-filter>
        </service>

payService.java

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

import com.ldw.alipay.publicbusiness.Stub;

public class payService extends Service {

	@Override
	public IBinder onBind(Intent intent) {
		// TODO Auto-generated method stub
		return new zhongjian();
	}
	
	class zhongjian extends Stub{

		@Override
		public void pay() throws RemoteException {
			// TODO Auto-generated method stub
			//调用服务的pay方法
			payService.this.pay();
		}
		
	}
	
	public void pay(){
		System.out.println("pay支付");
	}
