You are supporting a Boolean parameter on the @PreferenceChange annotation (but not mentioned in documentation), and you are not supporting a

 Set<String>  

parameter (but is reported in the documentation, you probably only meant to say that Set is supported) Finally the Long parameter is not supported (and correctly not reported in the documentation).
Maybe while you are at it you can also change @SharedPref to support Double, and also make @PreferenceChange support doubles?
