UnsupportedOperationException: CalendarView r

UnsupportedOperationException: CalendarView r

I have a problem with date picking in my project. I am getting the error:

 java.lang.UnsupportedOperationException: CalendarView does not exists for the new DatePicker
            at android.widget.DatePickerCalendarDelegate.getCalendarView(DatePickerCalendarDelegate.java:498)

            at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:698)

only for the lipopic system. Is there a way to handle this?

Edit: This is problematic code:

 IDatePickerInFilter act = (IDatePickerInFilter) activity;
                datePicker.setCalendarViewShown(false);
                act.getDateDialog(new DateToTimestampConverter().getStringDateFromTimestamp(datePicker.getCalendarView().getDate()));

To save time for others like me, as mentioned by @calvinfly:

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
    // do something for phones running an SDK before lollipop
    // e.g. datePicker.getCalendarView() ...
} else {
    // Do something for lollipop and above versions
}

The real problem is how to get the selected date from API 21. The pre-21 common approach was to use CalendarView

API 21+, the only possible way seems to provide OnDateChangedListener

in DataPicker

init

.

datePicker.init(year, month, day, new DatePicker.OnDateChangedListener() {
    @Override
    public void onDateChanged(DatePicker view, 
        int year, int monthOfYear, int dayOfMonth) {
        // do the date stuff
    }
});

The error message is also a bit over the top - "new DatePicker" does not refer to the new DatePicker (so you can expect to be able to run it), but to the new version of DatePicker available since API 21 (which throws an error whenever you ask CalendarView

).
