android - Strange Thread.sleep behaviour -

So I want to wait 60 seconds before uploading the file to the server and here is my "wait" code:

 try  {log (i.e., "waiting for 1 minute before uploading"); For (int i = 0; i <60; i ++) {debug.log ((60 - i) + "seconds remaining ..."); Thread.Sleep (1000); }} Grip (Interrupted e) e.printStackTrace (); }   
 And I'm left for 13 seconds. It is always stuck on "13 seconds left ..." after waiting for 1 hour! Any help with this please?  
 The BitDebug.log is similar to Log.i, except that it adds the array to the array list as well.   
 
 
  try using the termatask  class ITEAD  < P> In this  wait (tall millisecond)  method and applies  runner  which you can use as a thread.  
 or the  timer  class can also help you.
