Android之AIDL入门示例

package com.test.aidl;

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

public class MyService extends Service {
	public class MyServiceImpl extends IMyService.Stub {
		public String getValue() throws RemoteException {
			return "Android 链接成功";
		}
	}

	public IBinder onBind(Intent intent) {
		return new MyServiceImpl();
	}
}

IMyService.aidl中
package com.test.aidl;
interface IMyService
{
   String getValue();
}
