   *   * `minDate` (`Date` or timestamp in milliseconds) - minimum date that can be selected
   *   * `maxDate` (`Date` object or timestamp in milliseconds) - minimum date that can be selected
   *   * `mode` (`enum('no_arrows', 'default')`) - To set the date-picker mode to no_arrows/default
   *            - 'no_arrows': Show a date picker without arrows at the top bar
   *            - 'default': Show the basic date picker
   *   *  `weekDayLabels` (array of strings) the day labels that appears on the calendar
   *
   * 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.
