fun arePreferenceContentsTheSame(p1: Preference, p2: Preference): Boolean

arePreferenceItemsTheSame
fun arePreferenceItemsTheSame(p1: Preference, p2: Preference): Boolean
Called to determine if two objects represent the same item
This method will not be able to track replaced Preference objects if they do not have a unique key.
