Help with Preferences and Android Live Wallpaper

Basically what I want to do is when the preference is switched from the default to whatever to load up a new set of parallax backgrounds. With the code now which is probably over complicated and maybe completely off When I switch my preferences nothing changes. You can definitely tell I'm a novice but, your help would greatly be appreciated and I would gladly credit you in the app when I post it. Also if you need more of the code just ask.

Have you updated your settings class to link to your livewallpaper and use the same shared preference name?

For example;

public class Settings extends PreferenceActivity
implements SharedPreferences.OnSharedPreferenceChangeListener {
@Override
    protected void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        getPreferenceManager().setSharedPreferencesName(
                livewallpaper.SHARED_PREFS_NAME);

If you don't then you won't get any of the setting changes. I'm assuming you are using the Livewallpaper template that you can get from the andengine site.
