aSmack 连接到 openfire。无法连接，openfire 错误日志显示“无法识别的 SSL 消息，明文连接？”

Question

您好，我正在尝试连接到 openfire 服务器。使用以下代码：

        ConnectionConfiguration config = new ConnectionConfiguration(hostName, 5222);
        XMPPConnection connection = new XMPPConnection(config);

        try {
            connection.connect();
        } catch (XMPPException e) {
            if (e != null){
                Log.d(",myapp", Log.getStackTraceString(e));
            }
        }
        try {
            connection.login(userName, "password");
        } catch (XMPPException e) {
            if (e != null){
                Log.d("XMPPConnection", "Authentication Failure");
            }
        }

connection.connect() 失败；堆栈跟踪是：

我尝试在连接配置上使用不同的设置，例如使用安全模式。我也尝试过给它一个回调处理程序，但从未调用过。

编辑：启用调试后，我得到了这个：

通过从 ConnectionConfiguration 中删除端口号解决了这个问题。
