Provides a series of static system-level constants of common events.
You need to use these constants as the input values of action when you call Intent.setAction(String) in CommonEventData#CommonEventData(Intent) to set the common event content to be published, or when you call MatchingSkills#addEvent(String) in CommonEventSubscribeInfo#CommonEventSubscribeInfo(MatchingSkills) to set the filter criteria for subscribing to common events.
