My save setting function:

    public void saveSettings (ObjectSettings settings) {
        getContentResolver ().delete(ProviderSettings.CONTENT_URI, null, null);
        ContentValues values = new ContentValues ();
        values.put(ProviderSettings.coname, settings.getCoName());
        values.put(ProviderSettings.coaddress, settings.getCoAddress ());
        values.put(ProviderSettings.cocity, settings.getCoCity ());
        values.put(ProviderSettings.costate, settings.getCoState ());
        values.put(ProviderSettings.cszip, settings.getCoZip ());
        values.put(ProviderSettings.apiurl, settings.getApiUrl ());
        getContentResolver().insert(ProviderSettings.CONTENT_URI, values);
    }
