I've implemented my own PreferenceFragment subclass (detailed here), and want to listen for preference changes within it. PreferenceFragment provides you with two ways of doing this:

getPreferenceManager().getSharedPreferences().registerOnSharedPreferenceChangeListener(this);

and

getPreferenceScreen().getSharedPreferences().registerOnSharedPreferenceChangeListener(this);

Which one should be used? What's the difference? I don't really understand the distinction made in the Android docs.
