Android DatePickerDialog: Set min and max date for selection

CODE SNIPPTS:

private DatePickerDialog.OnDateSetListener mDateSetListener;

Calendar cal = Calendar.getInstance();
int year = cal.get(Calendar.YEAR);
int month = cal.get(Calendar.MONTH);
int day = cal.get(Calendar.DAY_OF_MONTH);


DatePickerDialog dialog = new DatePickerDialog(
        context,
        android.R.style.Theme_Holo_Light_Dialog_MinWidth,
        mDateSetListener,
        year,month,day);
//Getting Today date to calendar2
final Calendar calendar2 = Calendar.getInstance();
//Set Minimum date of calendar
calendar2.set(2019, 1, 1);
dialog.getDatePicker().setMinDate(calendar2.getTimeInMillis());

dialog.getDatePicker().setMaxDate(new Date().getTime());
Objects.requireNonNull(dialog.getWindow()).setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
dialog.show();

CODE EXAMPLE ON EDIT TEXT CLICK: date format like 28-JUL-21

date_dose_first.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Calendar cal = Calendar.getInstance();
        int year = cal.get(Calendar.YEAR);
        int month = cal.get(Calendar.MONTH);
        int day = cal.get(Calendar.DAY_OF_MONTH);


        DatePickerDialog dialog = new DatePickerDialog(
                context,
                android.R.style.Theme_Holo_Light_Dialog_MinWidth,
                mDateSetListener,
                year,month,day);
        //Getting Today date to calendar2
        final Calendar calendar2 = Calendar.getInstance();
        //Set Minimum date of calendar
        calendar2.set(2019, 1, 1);
        dialog.getDatePicker().setMinDate(calendar2.getTimeInMillis());

        dialog.getDatePicker().setMaxDate(new Date().getTime());
        Objects.requireNonNull(dialog.getWindow()).setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

This code simply show you a DatePickerDialog with Minimum and Maximum date,month and year,whatever you want just modify it.
final Calendar calendar = Calendar.getInstance();
                DatePickerDialog dialog = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker arg0, int year, int month, int day_of_month) {
                        calendar.set(Calendar.YEAR, year);
                        calendar.set(Calendar.MONTH, (month+1));
                        calendar.set(Calendar.DAY_OF_MONTH, day_of_month);
                        String myFormat = "dd/MM/yyyy";
                        SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.getDefault());
                        your_edittext.setText(sdf.format(calendar.getTime()));
                    }
                },calendar.get(Calendar.YEAR),calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
                dialog.getDatePicker().setMinDate(calendar.getTimeInMillis());// TODO: used to hide previous date,month and year
                calendar.add(Calendar.YEAR, 0);
                dialog.getDatePicker().setMaxDate(calendar.getTimeInMillis());// TODO: used to hide future date,month and year
                dialog.show();
