Android状态栏通知不加载

Question

我希望这个问题只是与模拟器有关，基本上我得到一个服务，设置一个计时器，只要timertask运行下面的代码应该执行：

 String ns = Context.NOTIFICATION_SERVICE; 
     NotificationManager mNotificationManager = (NotificationManager)getSystemService(ns); 

     int icon = R.drawable.androidapplogo; 
     CharSequence tickerText = "Ticker Text"; 
     long when = System.currentTimeMillis(); 

     Notification notification = new Notification(icon, tickerText, when); 
     Context context = getApplicationContext(); 
     CharSequence contentTitle = "My Notification"; 
     CharSequence contentText = "Hello World!";   

     //Do i need this? 
     Intent notificationIntent = new Intent(); 
     PendingIntent contentIntent = PendingIntent.getActivity(ctx, 0, notificationIntent, 0);   

     notification.setLatestEventInfo(context, contentTitle, contentText, null); 
     mNotificationManager.notify(1, notification); 

我遇到的问题是，当通知被调用时，它会出现在状态栏中，但是当我点击图标时，它只是一个蓝色圆圈。我没有自己的android手机，所以即时猜测，这意味着它试图加载的东西。

顺便说一句，我已经几乎取消了代码从这里：http://developer.android.com/guide/topics/ui/notifiers/notifications.html

所以我的问题是双重的： - 这是怎么回事，难道是无法加载的东西吗？ - 有关如何解决它的任何想法，或者是否值得寻找新的通知形式

编辑：我很抱歉家伙，发现问题是，你需要拖下通知窗口 - 我很少使用android x ）
