Smack 4.2.0-beta1 创建群聊“MultiUserChat”时出错。无法从外部包访问

Question

我正在开发聊天应用程序。我已经进行了一对一的聊天。但我无法创建群聊，因为它显示以下错误

    'MultiUserChat(org.jivesoftware.smack.XMPPConnection, org.jxmpp.jid.EntityBareJid, org.jivesoftware.smackx.muc.MultiUserChatManager)' is not public in 'org.jivesoftware.smackx.muc.MultiUserChat'. 
Cannot be accessed from outside package

我看到了一些关于使用multiUserChat = new MultiUserChat(connection,room_name);创建群聊的答案。

但是在 4.2.0-beta1 版本中不允许我们访问这个类。

我在下面添加了我的代码

 public void createGroupChat() {
            // Create a MultiUserChat using a Connection for a room
    // (room name as the second parameter)
            try {
                Resourcepart nikname = Resourcepart.from("admin");

                MultiUserChat mMultiUserChat = new MultiUserChat(connection, "room@conference.myserver");
                mMultiUserChat.create(nikname);
                Form form = mMultiUserChat.getConfigurationForm().createAnswerForm();
                form.setAnswer("muc#roomconfig_publicroom", true);
                form.setAnswer("muc#roomconfig_roomname", "room");
                form.setAnswer("muc#roomconfig_roomowners", "owner");
                form.setAnswer("muc#roomconfig_persistentroom", true);
                mMultiUserChat.sendConfigurationForm(form);
            } catch (XmppStringprepException e) {
                e.printStackTrace();
            } catch (MultiUserChatException.MucAlreadyJoinedException e) {
                e.printStackTrace();
            } catch (InterruptedException e) {
                e.printStackTrace();
            } catch (XMPPException.XMPPErrorException e) {
                e.printStackTrace();
            } catch (MultiUserChatException.MissingMucCreationAcknowledgeException e) {
                e.printStackTrace();
            } catch (NotConnectedException e) {
                e.printStackTrace();
            } catch (SmackException.NoResponseException e) {
                e.printStackTrace();
            } catch (MultiUserChatException.NotAMucServiceException e) {
                e.printStackTrace();
            }
        }

谁能告诉我如何在最新的 smack 4.2.0-beta1 版本中创建群组？

如果我问错了什么对不起。

我从下面的链接中找到了创建群聊的答案

https://github.com/igniterealtime/Smack/blob/master/documentation/extensions/muc.md

我也添加了我的新代码。它可能对其他一些开发人员有所帮助

 public void createGroupChat() {
        // Create a MultiUserChat using a Connection for a room
// Get the MultiUserChatManager
        MultiUserChatManager manager = MultiUserChatManager.getInstanceFor(connection);
        try {
            EntityBareJid jid = JidCreate.entityBareFrom("myroom" + "@"
                    + context.getString(R.string.serviceNameOld));

// Create a MultiUserChat using an XMPPConnection for a room
            MultiUserChat muc = manager.getMultiUserChat(jid);

// Prepare a list of owners of the new room
            Set<Jid> owners = JidUtil.jidSetFrom(new String[]{"mathan@example.org", "kumar@example.org"});

// Create the room
            Resourcepart nickname = Resourcepart.from("mathan");
            muc.create(nickname).getConfigFormManager().setRoomOwners(owners).submitConfigurationForm();

        } catch (XmppStringprepException e) {
            e.printStackTrace();
        } catch (MultiUserChatException.MucAlreadyJoinedException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (XMPPException.XMPPErrorException e) {
            e.printStackTrace();
        } catch (MultiUserChatException.MissingMucCreationAcknowledgeException e) {
            e.printStackTrace();
        } catch (NotConnectedException e) {
            e.printStackTrace();
        } catch (SmackException.NoResponseException e) {
            e.printStackTrace();
        } catch (MultiUserChatException.NotAMucServiceException e) {
            e.printStackTrace();
        } catch (MultiUserChatException.MucConfigurationNotSupportedException e) {
            e.printStackTrace();
        }
    }
