Android datepicker min max date before api level 11

Question

I am trying to set the min and max date of the date picker in Android to before API level 11. I used the following code:

mDatePickerField = startDatePickerDi

Based on @yostyle's answer, I've made a method which sets the minimum and maximum date for an DatePicker. My DatePicker was used inside an AlertDialog because I needed some extra customizations, but this method can be used directly on any DatePickerDialog or for any custom DatePicker's:

/**
     * Compat utility method that will set the minimum date and the maximum date for the DatePicker view.
     * 

     * If the current API is greater than 11, than the normal {@link android.widget.DatePicker#setMinDate(long)} and
     * {@link android.widget.DatePicker#setMaxDate(long)} methods will be used.
     * 

     *
     * @param minCalendar
     *         The minimum date for the picker
     * @param maxCalendar
     *         The maximum date for the picker
     */
    private void initDatePickerCompat(final Calendar minCalendar, final Calendar maxCalendar) {
        if (null == mDatePicker) {
            // Exit early if DatePicker view was not initialized
            return;
        }
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
            // (mDatePicker is a DatePicker)
            mDatePicker.setMinDate(minCalendar.getTimeInMillis());
            mDatePicker.setMaxDate(maxCalendar.getTimeInMillis());
        } else {
            final int minYear = minCalendar.get(Calendar.YEAR);
            final int minMonth = minCalendar.get(Calendar.MONTH);
            final int minDay = minCalendar.get(Calendar.DAY_OF_MONTH);

            final int maxYear = maxCalendar.get(Calendar.YEAR);
            final int maxMonth = maxCalendar.get(Calendar.MONTH);
            final int maxDay = maxCalendar.get(Calendar.DAY_OF_MONTH);

            mDatePicker.init(minYear, minMonth, minDay, new DatePicker.OnDateChangedListener() {
                @Override
                public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                    Calendar newCalendar = Calendar.getInstance();
                    newCalendar.set(year, monthOfYear, dayOfMonth);

                    if (newCalendar.after(maxCalendar)) {
                        // MAX
                        view.updateDate(maxYear, maxMonth, maxDay);
                    } else if (newCalendar.before(minCalendar)) {
                        // MIN
                        view.updateDate(minYear, minMonth, minDay);
                    } else {
                        // BETWEEN
                        view.updateDate(year, monthOfYear, dayOfMonth);
                    }
                }
            });
        }
    }

Keep in mind that this method should be called after DatePicker was initialized, like this:

mDatePicker = (DatePicker) view.findViewById(R.id.datePicker);
mDatePicker.init(year, monthOfYear, dayOfMonth, this);
DateTime minDate = new DateTime();
DateTime maxDate = minDate.plusYears(10);
// Set the minimum and the maximum date for the date picker
initDatePickerCompat(minDate.toCalendar(Locale.getDefault()), maxDate.toCalendar(Locale.getDefault()));
