Android: How to calculate age not by year only

Question

I have a date picker that able to choose any dates. and I want to calculate my age from date today and my birthdate. I manage to come up with this code :

com.wdullaer.materialdatetimepicker.date.DatePickerDialog bday_dialog = com.wdullaer.materialdatetimepicker.date.DatePickerDialog.newInstance(new DatePickerDialog.OnDateSetListener() {
                @Override
                public void onDateSet(DatePickerDialog view12, int year, int monthOfYear, int dayOfMonth) {
                    Calendar c = Calendar.getInstance();
                    c.set(Calendar.YEAR, year);
                    c.set(Calendar.MONTH, monthOfYear);
                    c.set(Calendar.DAY_OF_MONTH, dayOfMonth);

                    String strBDate = (monthOfYear + 1) + "/" + dayOfMonth + "/" + year;
                    mdob_et.setText(strBDate);
                    age.setText(Integer.toString(calculateAge(c.getTimeInMillis())));
                }
                int calculateAge(long date){
                    Calendar dob = Calendar.getInstance();
                    dob.setTimeInMillis(date);
                    Calendar today = Calendar.getInstance();
                    int f_age = today.get(Calendar.YEAR) - dob.get(Calendar.YEAR);
                    if(today.get(Calendar.DAY_OF_MONTH) < dob.get(Calendar.DAY_OF_MONTH)){
                        f_age--;
                    }
                    return f_age;
                }
            }, Year,Month,Day);

however it only calculates the year not the date today. any suggestions or workarounds with my code is much appreciated, TIA!!

There is nothing like Android in this problem. You can simply do R&D on the logic of the age calculation and implement the same logic in Java or Kotlin. — Paresh Mayani, Aug 28 '19 at 02:43
