Add the ability to define a Preference Controller in xml using the 'controller' tag. This is useful for two reasons: - It allows the controllers to be instantiated via reflection for Slices and Dashboard fragment - Removes the requirement that controllers be defined manually in Fragments In order to be instantiable, they must have a unified construction following either: ClassName(Context) ClassName(Context, String) Also added a robotest that verifies that all controllers defined in XML follow the constructor schema, and extend BasePreferenceController. Test: robotests Bug: 67996923 Change-Id: I304b35dc666daebecf0c9e286696f3f2a510704a
