            placeholderColor = r.getColor(R.color.iphone_albumset_placeholder);

            slotViewSpec = new SlotView.Spec();
            slotViewSpec.rowsLand = r.getInteger(R.integer.iphone_albumset_rows_land);
            slotViewSpec.rowsPort = r.getInteger(R.integer.iphone_albumset_rows_port);
            /// M: [FEATURE.ADD] fancy layout @{
            if (FancyHelper.isFancyLayoutSupported()) {
                slotViewSpec.colsLand = FancyHelper.ALBUMSETPAGE_COL_LAND;;
                slotViewSpec.colsPort = FancyHelper.ALBUMSETPAGE_COL_PORT;
