Using reflection to find and hide UI elements is not really a great practice. In your case, it stopped working in lollipop because the mDaySpinner is now contained in an internal private static DatePickerSpinngerDelegate class within the DatePicker class.

I would recommend going through the view hierarchy to find and hide the day spinner element instead. I wrote the following code that works in lollipop:

if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    int daySpinnerId = Resources.getSystem().getIdentifier("day", "id", "android");
    if (daySpinnerId != 0) {
        View daySpinner = datePicker.findViewById(daySpinnerId);
        if (daySpinner != null) {
            daySpinner.setVisibility(View.GONE);
        }
    }
}
