使用唯一的requestCode取消PendingIntent(Cancelling a PendingIntent with unique requestCode)

 我在取消pendingintent时遇到了麻烦。 现在我像这样创建我的待定意图：  
 Intent intent = new Intent(_self, NotificationService.class); PendingIntent pi = PendingIntent.getService(this, task.getID, intent, 0);  
 task.getID在这里是一个唯一的int。 稍后在我的应用程序中，用户可以编辑“任务”，并可以决定取消通知（pendingintent）。 我试着像这样取消pendingintent：  
 Intent intent = new Intent(_self, NotificationService.class); PendingIntent pIntent = PendingIntent.getBroadcast(_self, task.getID, intent , PendingIntent.FLAG_NO_CREATE); 
 pIntent.cancel();  
 但它不起作用！ 通知仍然显示。 在这种情况下，task.getID引用之前创建的唯一ID。  
 我尝试了几个不同的参数，PendingIntent.FLAG_NO_CREATE返回null，FLAG_UPDATE_CURRENT不起作用，FLAG_CANCEL_CURRENT也没有。 有人可以帮我这个，看看我做错了什么？ 

I'm having trouble with cancelling my pendingintent. Right now I create my pending intent like so: 
Intent intent = new Intent(_self, NotificationService.class); PendingIntent pi = PendingIntent.getService(this, task.getID, intent, 0); 
task.getID is a unique int here. Later on in my app a user can edit a "task" and can decide to cancel the notifications (pendingintent). I try to cancel the pendingintent like so: 
Intent intent = new Intent(_self, NotificationService.class); PendingIntent pIntent = PendingIntent.getBroadcast(_self, task.getID, intent , PendingIntent.FLAG_NO_CREATE);
 pIntent.cancel(); 
But it doens't work! The notifications still shows up. In this case, task.getID refers to the unique id that was created before. 
I've tried several different parameters, PendingIntent.FLAG_NO_CREATE returns null, FLAG_UPDATE_CURRENT doens't work and FLAG_CANCEL_CURRENT neither. Can somebody please help me with this and see what it is I am doing wrong?

 eval不是必需的，但您的代码也不起作用。 它不是有效的Ruby代码。 它应该是  
map.each do |old, new|
  task(old) do
    warn "[DEPRECATED] `#{old}' is deprecated. Use `#{new}' instead."
    find_and_execute_task(new)
  end
end

eval is not necessary, but your code will not work either. It is not valid Ruby code. It should be 
map.each do |old, new|
  task(old) do
    warn "[DEPRECATED] `#{old}' is deprecated. Use `#{new}' instead."
    find_and_execute_task(new)
  end
end
