找出Looper或HandlerThread中的泄漏问题

Question

我使用了一些处理程序

           new Handler(Looper.getMainLooper()).post(new Runnable() {

            @Override
            public void run() {
                try{
                    Messages.onAcknowledgeReceived();                                       

                }catch(Exception e){
                    e.printStackTrace();
                }

                }
            }); 

它每15秒执行一次,有时它开始抛出一些警告

 The Looper class instance count has over a limit(100). There should be some leakage of Looper or HandlerThread.
 12-16 12:16:11.357: E/Looper(4647): Looper class instance count = 221
 12-16 12:16:11.357: E/Looper(4647): Current Thread Name: IntentService[AppService]

我的编程方法有什么问题吗？我仍然不明白这段代码中的泄漏在哪里.
