I have preferences working and I am using a combination of CheckBoxPreference and EditTextPreference. I would like to replace one of them with a DatePickerDialog.
While looking for a TimePicker to use in preferences I found this thread.
I'd like to point out that there is also a TimePicker project in that repo (link).
The only problem is that the default.jardesc is not available, but can easily be made from the corresponding one in the DatePicker project.
