Fixed a crash when creating a public notification group

        if (areGutsExposed()) {

            return false;

        }

        if (mIsSummaryWithChildren) {

            return true;

        }

        NotificationContentView showingLayout = getShowingLayout();

        NotificationHeaderView notificationHeader = showingLayout.getVisibleNotificationHeader();

        return notificationHeader != null;

        return getVisibleNotificationHeader() != null;

    }
