1.定义aidl文件

a.ITestService.aidl

 

package com.open.aidl.service;import com.open.aidl.service.ITestServiceCallback;interface ITestService {    void registerCallback(ITestServiceCallback cb);        void unregisterCallback(ITestServiceCallback cb);        int request(inout Bundle mBundle);}

b.ITestServiceCallback.aidl

package com.open.aidl.service;oneway interface ITestServiceCallback {    void onResponse(inout Bundle mBundle);}

2.定义Activity

3.定义Service.

package com.open.aidl.service;import android.app.Service;import android.content.Intent;import android.os.Bundle;import android.os.Handler;import android.os.IBinder;import android.os.IInterface;import android.os.RemoteCallbackList;import android.os.RemoteException;import android.util.Log;/** * 后台服务类 * @author DexYang * */public class TestService extends Service {	private final String TAG="TestService";	private Object mCallbacksLock=new Object();		private Handler mHandler=new Handler();		@Override	public void onCreate() {		super.onCreate();Log.v(TAG, "onCreate()");	}		@Override    public void onStart(Intent intent, int startId) {Log.v(TAG, "onStart()");        handleCommand(intent);    }	@Override	public int onStartCommand(Intent intent, int flags, int startId) {Log.v(TAG, "onStartCommand()");		handleCommand(intent);		return START_STICKY;	}	private void handleCommand(Intent intent)	{			}		@Override	public IBinder onBind(Intent arg0) {Log.v(TAG, "onBind()");		if(null!=arg0&&TestService.class.getName().equals(arg0.getAction()))		{			handleCommand(arg0);		}		return mBinder;	}    @Override	public void onRebind(Intent intent) {Log.v(TAG, "onRebind()");		if(TestService.class.getName().equals(intent.getAction()))		{			handleCommand(intent);		}		super.onRebind(intent);	}    	@Override	public boolean onUnbind(Intent intent) {Log.v(TAG, "onUnbind()");		return true;	}	@Override	public void onDestroy() {Log.v(TAG, "onDestroy()");		mCallbacks.kill();		android.os.Process.killProcess(android.os.Process.myPid());		super.onDestroy();	}		/**	 * Binder 相关	 */	private final CusRemoteCallbackList
    
      mCallbacks= new CusRemoteCallbackList
     
      ();	private ITestService.Stub mBinder=new ITestService.Stub() {		@Override		public int request(Bundle mBundle) throws RemoteException {Log.v(TAG,"call from Activity request ");			mHandler.postDelayed(new Runnable(){							@Override				public void run() {					synchronized (mCallbacksLock) 					{						int callbacksNum = mCallbacks.beginBroadcast();				        for (int i=callbacksNum-1; i>=0; i--) 				        {				            try {			   						mCallbacks.getBroadcastItem(i).onResponse(null);;				            } catch (Exception e) {				            	e.printStackTrace();				            }				        }				        mCallbacks.finishBroadcast();					}				}							}, 3000);			return 0;		}		@Override		public void registerCallback(ITestServiceCallback cb)				throws RemoteException {Log.v(TAG,"registerCallback :");			if (cb != null)			{				mCallbacks.register(cb);			}		}		@Override		public void unregisterCallback(ITestServiceCallback cb)				throws RemoteException {Log.v(TAG,"unregisterCallback :");				if (cb != null) 				{					mCallbacks.unregister(cb);				}		}	};		/**	 * 经过测试onCallbackDied()方法，只有在bindService()，没有调用unbind()方法process就挂了的情况下才会执行	 * @author Administrator	 * @param 
      
       	 */	private class CusRemoteCallbackList
       
         extends RemoteCallbackList
        
         	{		@Override		public void onCallbackDied(E callback) {Log.v(TAG, "CusRemoteCallbackList onCallbackDied 1");			super.onCallbackDied(callback);		}		@Override		public void onCallbackDied(E callback, Object cookie) {Log.v(TAG, "CusRemoteCallbackList onCallbackDied 2");						super.onCallbackDied(callback, cookie);		}	} }
        
       
      
     
    

4.配置AndroidManifest.xml文件

 

5.测试运行.

 

点击bind service , 在TestService中 打印了call from Activity，说明Activity 调用 Service 成功； 3秒后在Activity中 打印了call from service，说明Service 调用 Activity 成功。
