*
* - `date` (`Date` object or timestamp in milliseconds) - date to show by default
* - `minDate` (`Date` or timestamp in milliseconds) - minimum date that can be selected
* - `maxDate` (`Date` object or timestamp in milliseconds) - maximum date that can be selected
* - `mode` (`enum('calendar', 'spinner', 'default')`) - To set the date-picker mode to calendar/spinner/default
* - 'calendar': Show a date picker in calendar mode.
* - 'spinner': Show a date picker in spinner mode.
* - 'default': Show a default native date picker(spinner/calendar) based on android versions.
*
* Returns a Promise which will be invoked an object containing `action`, `year`, `month` (0-11),
* `day` if the user picked a date. If the user dismissed the dialog, the Promise will
* still be resolved with action being `DatePickerAndroid.dismissedAction` and all the other keys
* being undefined. **Always** check whether the `action` before reading the values.
*
* Note the native date picker dialog has some UI glitches on Android 4 and lower
* when using the `minDate` and `maxDate` options.
