No. You call that method on a SharedPreferences object. For a
PreferenceActivity, you specifically call it on a SharedPreferences
object you get from PreferenceManager.getDefaultSharedPreferences().
getDefaultSharedPreferences() can be called with any Context as its
parameter (e.g., your main activity). The listener you supply then
reacts to the changing preferences however is necessary.
