PreferenceFragment with v4 Fragments

Question

In my application I am using v4 support library to display user preferences in a ViewPager with tabs. Until now I was using some custom Fragment that reproduces what PreferenceFragment does.

For instance, there are some suggestions here.

After updating all my Android SDK to the latest versions, these custom Fragments stopped working, in particular they seem to fail this method invocation by reflection:

static PreferenceScreen inflateFromResource(PreferenceManager manager,
        Activity activity, int resId, PreferenceScreen screen) {
    try {
        Method m = PreferenceManager.class.getDeclaredMethod("inflateFromResource", Context.class, int.class, PreferenceScreen.class);
        m.setAccessible(true);
        PreferenceScreen prefScreen = (PreferenceScreen) m.invoke(manager, activity, resId, screen);
        return prefScreen;
    } catch (Exception e) {
        Log.w(TAG, "Couldn't call PreferenceManager.inflateFromResource by reflection", e);
    }
    return null;
}

Since nobody can change exposure of the method in the APIs, is it still possible to create a PreferenceScreen starting from a XML file?
