Can u guys have any idea?

My code:

    // Create the list of PrivacyItem that will allow or
    // deny some privacy aspect

    List<PrivacyItem> privacyItems = new Vector<PrivacyItem>();

    PrivacyItem item = new PrivacyItem(PrivacyItem.Type.jid.toString(),
            false, 1);
    item.setValue(userName);
    privacyItems.add(item);

    // Create the new list.

    try {
        PrivacyListManager privacyManager = new PrivacyListManager(connection);
        privacyManager = PrivacyListManager
                .getInstanceFor(connection);
        privacyManager.createPrivacyList(listName, privacyItems);

    } catch (XMPPException e) {
        System.out.println("PRIVACY_ERROR: " + e);
    }
}

Answer 1

try this ...

public boolean blockFriend(String friendName) {

    PrivacyItem item=new PrivacyItem(PrivacyItem.Type.jid,friendName, false, 7);
    PrivacyListManager privacyManager = PrivacyListManager.getInstanceFor(connection);
    List<PrivacyItem> list=new ArrayList<PrivacyItem>();
    list.add(item);

    try {
        privacyManager.updatePrivacyList(NEWLIST, list);
        privacyManager.setActiveListName(NEWLIST);
        return true;
    } catch (SmackException.NoResponseException |XMPPException.XMPPErrorException | SmackException.NotConnectedException e) {
        e.printStackTrace();
        return false;
    }


}

and for unblock just replace false with true in object of privacyitem `
