Question

我已经使用aSmack实现了一个聊天应用程序。我使用openfire服务器作为聊天服务器。所有这些应用程序都在同一台机器上运行。但是当我尝试在两个模拟器之间发送消息时，只有一个模拟器成功接收消息。其他客户端将不会收到任何消息。但是从这两个模拟器中我能够向pigin（IM clinet）发送消息。此外，如果我使用gmail.com作为聊天服务器一切正常。

用于登录的用户名 jayamal suchith （openfire表示用户在线）

用于发送消息的名称 jayamal @ elearn（elearn是我使用openfire在我的机器上创建的域名） suchith @ elearn
（但在openfire档案中显示一个名称为jayamal @ elearn / Smack，尝试向该名称发送消息，但它也不成功）

请帮助纠正此问题。非常感谢您的帮助。

对不起，这有点晚了。

您可以发送给IM客户端（pidgin）的一个用户可以发送回您的模拟器。即你可以在任何一个模拟器中收到吗？

邮件接收是基于事件的，因此您无需使用按钮单击将其设置为关闭。

看看这个很好的例子。作者：Davanum Srinivas

我已经对它进行了相当广泛的修改，但基本代码仍然非常有用。
