关于一个程序中多个Notification的精确控制

Problem: 
When a notification is selected, Tabs activity is called passing the intent. I want to access the unique notificationId of the notification that was selected in Tabs. I tried intent.putExtra() to save the notificationId in the intent. But, for multiple notifications its overwriting the notificationId and returns the latest one. I dont understand as to why this is happening and how can i avoid this overwriting of notificationId. 

Answer: 
I got the answer. The intents were getting cached in. To, make a new intent, just add the following piece of code: 

  
    

   
     1 
   
     intent.setData((Uri.parse(
   
     "
   
     custom://
   
     "
   
     +
   
     System.currentTimeMillis())));
  
    

This makes the intent unique. 
Also, someone suggested me the following piece of code to make the intent unique: 

  
    

   
     1 
   
     intent.setAction(
   
     "
   
     actionstring
   
     "
   
      
   
     +
   
      System.currentTimeMillis()); 
  
    

It didnt help me, but might be of help to someone else.
