SimpleDateFormat sdf = new SimpleDateFormat("mm-MM-yyyy");
Date d1 = sdf.parse(date1);
Date d2 = sdf.parse(date2);
int days = d2.getTime() - d1.getTime())/1000/60/60/24;

You can use this function...

private long countDays(String date1, String date2)
            String date[] = date1.split("-");
            Calendar d1 = new GregorianCalendar(Integer.parseInt(date[2]), Integer.parseInt(date[1]), Integer.parseInt(date[0]));
            date = date2.split("-");
            Calendar d2 = new GregorianCalendar(Integer.parseInt(date[2]), Integer.parseInt(date[1]), Integer.parseInt(date[0]));
            long diff = d1.getTimeInMillis() - d2.getTimeInMillis();
                  diff = d2.getTimeInMillis() - d1.getTimeInMillis();
            return diff/(24*60*60*1000);
