无法将aSmack客户端与Android中的我的ejabberd2服务器连接

我正在使用XMPP创建聊天应用程序：

为此，我在android应用程序中使用eJabberd2作为服务器，使用asmack lib asmack-2010.05.07.jar作为客户端

我可以连接主机talk.google.com，但无法连接我的eJabberd主机

我的代码是：

1.工作罚款：

2不工作：我的eJabberd打开了http://68.178.255.136:5280/admin/

O/p:

我认为问题在于您提供的端口，请使用5222而不是5280，因为在XMPP客户端中，5222而不是5280连接。
