private boolean hasPublishPermission() {
        Session session = Session.getActiveSession();
        return session != null
                && session.getPermissions().contains("publish_stream");
    }

private void getFacebookFriends(final Session session) {
        Session msession = session;
        if (msession.isOpened()) {


            if (!hasPublishPermission()) {
                if (progressDlg != null) {
                    progressDlg.dismiss();
                }

                        FindFriendsActivity.this, PERMISSIONS));
