I am getting the current date (in format 12/31/1999 i.e. mm/dd/yyyy) as using the below code:

Textview txtViewData;
txtViewDate.setText("Today is " +
        android.text.format.DateFormat.getDateFormat(this).format(new Date()));

and I am having another date in format as: 2010-08-25 (i.e. yyyy/mm/dd) ,

so I want to find the difference between date in number of days, how do I find difference in days?

(In other words, I want to find the difference between CURRENT DATE - yyyy/mm/dd formatted date)

        public void dateDifferenceExample() {

        // Set the date for both of the calendar instance
        GregorianCalendar calDate = new GregorianCalendar(2012, 10, 02,5,23,43);
        GregorianCalendar cal2 = new GregorianCalendar(2015, 04, 02);

        // Get the represented date in milliseconds
        long millis1 = calDate.getTimeInMillis();
        long millis2 = cal2.getTimeInMillis();

        // Calculate difference in milliseconds
        long diff = millis2 - millis1;

        // Calculate difference in seconds
        long diffSeconds = diff / 1000;

        // Calculate difference in minutes
        long diffMinutes = diff / (60 * 1000);

        // Calculate difference in hours
        long diffHours = diff / (60 * 60 * 1000);

        // Calculate difference in days
        long diffDays = diff / (24 * 60 * 60 * 1000);
    Toast.makeText(getContext(), ""+diffSeconds, Toast.LENGTH_SHORT).show();
