我正在尝试为我的应用程序进行多用户聊天。我已经完成了单用户通信的编码，它工作正常。我无法在多用户聊天中创建或加入群组。以下是我的代码。

在调用 join（）函数时尝试执行上述代码时出现XMPP错误。
错误 multiUserChat.createOrJoin（loginUser）这个地方。
XMPPError：remote-server-not-found - 取消at org.jivesoftware.smack.PacketCollector.nextResultOrThrow（PacketCollector.java:220） 在org.jivesoftware.smackx.muc.MultiUserChat.enter（MultiUserChat.java:311） 在org.jivesoftware.smackx.muc.MultiUserChat.createOrJoin（MultiUserChat.java:400） 在org.jivesoftware.smackx.muc.MultiUserChat.createOrJoin（MultiUserChat.java:376）
请帮帮我。在此先感谢。

我认为您在创建多用户聊天（getMultiUserChat）时没有正确传递jabber ID。创建jid的方式是roomName @ conferenceServername / resourceId。您需要检查在创建JID时需要附加的会议服务器名称应该是什么。这可以通过检查服务器端的配置或使用item discovery feature来完成，如果会议被用作XMPP端的单独组件。

对于群聊，您需要预先设置“会议”。与service_url。
示例代码：
final MultiUserChatManager multiUserChatManager =
MultiUserChatManager.getInstanceFor(abstractXMPPConnection);
final MultiUserChat multiUserChat =
multiUserChatManager.getMultiUserChat(
JidCreate.entityBareFrom(groupChatRoomName +
"@conference." + SERVICE_URL));
multiUserChat.create(Resourcepart.from((groupChatRoomName))
.getConfigFormManager()
.submitConfigurationForm();

创建房间并将成员添加到房间示例：请参考joinChatRoom（String userName，String roomName）函数来创建和加入房间。
