【问题描述】：

我正在使用 smack.jar 库。 我曾尝试通过以下代码在 android 中使用 xmpp 实现群聊：

MultiUserChat muc = new MultiUserChat(connection,groupName+"@"+Utils.SERVER_NAME);
    muc.create("nickname1");

    Form form = muc.getConfigurationForm();
    Form submitForm = form.createAnswerForm();
    for (Iterator fields = form.getFields();fields.hasNext();)
      FormField field = (FormField) fields.next();
        if(!FormField.TYPE_HIDDEN.equals(field.getType()) && field.getVariable()!= null)
            submitForm.setDefaultAnswer(field.getVariable());
        
                   
    submitForm.setAnswer("muc#roomconfig_publicroom", true);
    muc.sendConfigurationForm(submitForm);
    muc.join("nickname1");

出现“服务器无响应”等异常。有人知道怎么解决吗？

【问题讨论】：

Utils.SERVER_NAME 的值是多少？

openfire 服务器的 IP 地址/主机名。

我找到了解决方案，将 smack.jar 文件替换为 asmack.jar 并将 SmackAndroid.init() 放在代码的开头。

可能是您的域名（服务器名称）错误。您可以发布您正在使用的域（服务器名称）吗？

【参考方案1】：

我遇到了同样的问题，因为我使用的是域名chat.localhost。确保我们在multiUserManager.getMultUserChat("[e-mail]"); 中有conference 作为子域

同样重要的是使用ProviderManager用于 IQ 和 PacketExtension 目的。

public static void configure(ProviderManager pm) 

    // Private Data Storage

    pm.addIQProvider("query", "jabber:iq:private",

    // Time

    try 

        pm.addIQProvider("query", "jabber:iq:time",
                Class.forName("org.jivesoftware.smackx.packet.Time"));

     catch (ClassNotFoundException e)
