Sets the dismissal id for this notification. If a notification is posted with a
dismissal id, then when that notification is canceled, notifications on other wearables
and the paired Android phone having that same dismissal id will also be canceled. See
<a href="{@docRoot}wear/notifications/index.html">Adding Wearable Features to
Notifications</a> for more information.

@param dismissalId the dismissal id of the notification.
@return this object for method chaining
