无法连接到本地 Openfire 服务器（使用 smack api）

Question

我正在 android 上尝试此代码以连接到我的本地 XMPP 服务器

Thread t = new Thread(new Runnable() {
        @Override
        public void run() {
            // Create a connection
            ConnectionConfiguration connConfig = new ConnectionConfiguration(
                    "192.168.43.170", 5223, "192.168.43.170");
            XMPPConnection connection = new XMPPConnection(connConfig);

            try {
                connection.connect();
            } catch (XMPPException ex) {
            }
            try {
                // SASLAuthentication.supportSASLMechanism("PLAIN", 0);
                connection.login("nagham","123456");
                // Set the status to available
                Presence presence = new Presence(Presence.Type.available);
                connection.sendPacket(presence);
                setConnection(connection);
                Roster roster = connection.getRoster();
                Collection<RosterEntry> entries = roster.getEntries();
                for (RosterEntry entry : entries) {
                    Presence entryPresence = roster.getPresence(entry
                            .getUser());

                    Presence.Type type = entryPresence.getType();
                }
            } catch (XMPPException ex) {    
        }
        }
    });

但我得到以下异常：

    05-16 02:10:16.580: E/XMPPChatDemoActivity(24289): Failed to connect to 192.168.43.170

我哪里错了？ 请注意，我使用的是 asmack-2010.05.07

我已经解决了我的问题，只是将端口号从 5223 更改为 5222 并且每个人都不要忘记必须禁用您的防火墙。
