android - Error: no results found for query -

when i've tried run code:

parsequery<parseuser> query = parsequery.getquery("user");     query.getinbackground(fblogin.userobjid, new getcallback<parseuser>() {       public void done(parseuser object, parseexception e) {         if (e == null) {             ...         } else {           log.e("tag", "error: " + e.getmessage());         }       }     }); 

the "fblogin.userobjid" parse user id:

userobjid = (string) user.get("objectid"); 

well, when i've tried run code, got message:

11-27 13:48:32.827: e/tag(27174): error: no results found query 

what need fix it?

instead of:

userobjid = (string) user.get("objectid"); 

i wrote:

userobjid = parseuser.getcurrentuser().getobjectid();
