Android 获得；收件人不可用（404）“；在收到多用户聊天邀请后加入群时

我使用以下代码在android中创建组

MultiUserChat muc = new MultiUserChat(connection, groupName + "@conference.jabber.org");

setConfig(muc, groupName);
muc.create(groupName);
muc.join("ABC");
groups.add(groupName);


private void setConfig(MultiUserChat multiUserChat, String groupName) {
   try {

        Form form = multiUserChat.getConfigurationForm();
        Form submitForm = form.createAnswerForm();
        for (Iterator<FormField> fields = submitForm.getFields(); fields
                .hasNext();) {
            FormField field = (FormField) fields.next();
            if (!FormField.TYPE_HIDDEN.equals(field.getType())
                    && field.getVariable() != null) {
                submitForm.setDefaultAnswer(field.getVariable());
            }
        }

        List<String> owners = new ArrayList<String>();
        owners.add("abc" + "@" + "@conference.jaber.org");
        submitForm.setAnswer("muc#roomconfig_roomowners", owners);
        submitForm.setAnswer("muc#roomconfig_roomname", groupName);
        submitForm.setAnswer("muc#roomconfig_publicroom", true);
        submitForm.setAnswer("muc#roomconfig_persistentroom", true);

        multiUserChat.sendConfigurationForm(submitForm);
    } catch (Exception e) {
        e.printStackTrace();
    }

}

然后，下一个用户USER2在尝试使用加入组时也会收到邀请

MultiUserChat mucJoin = new MultiUserChat(connection, groupName);
mucJoin.join("USER2");

然后我得到了错误“收件人不可用（404）”

请让我知道我哪里做错了，为什么我会犯这个错误。 谢谢

我得到了问题的解决方案，在创建和加入房间之前，我正在配置房间，如下所示

setConfig(muc, groupName);
muc.create(groupName);
muc.join("ABC");
groups.add(groupName);

我只是改变了以下步骤

muc.create(groupName);
muc.join("ABC");
groups.add(groupName);
setConfig(muc, groupName);

我接受我的回答

muc.create(groupName);
muc.join("ABC");
groups.add(groupName);
setConfig(muc, groupName);
