I set some preferences up in an xml file and used the standard constructs (see code below) to make them available and updatable and all has been working fine. As these were for test purposes I now want to replace them with my actual app preferences (including completely removing some) but whatever I do it seems only to recognise the original ones I setup. I have even completely replaced the xml file with my new one - still it only finds the old preferences. I have also cleared the entries as shown in the code (map size is 0 after the commit()). Also it does not appear to let me change the xml filename from 'preferences.xml'. The code shows my new name of preferences_new.xml but this raises an error in Eclipse.
In calling activity onCreate:
// Display the fragment as the main content.
getFragmentManager().beginTransaction()
.replace(android.R.id.content, new PrefsFragment()).commit();
In PrefsFragment:
PreferenceManager pm = this.getPreferenceManager();
SharedPreferences sp = pm.getSharedPreferences();
Editor e = sp.edit();
e.clear();
e.commit();
Map <String, ?> map = sp.getAll();
int size = map.size();
// Load the preferences from an XML resource
addPreferencesFromResource(R.xml.preferences_new);
Old XML file:

I am almost at the 'tearing the hair out' stage, so any help would be greatly appreciated
