组件使用： ejabberd- 18.06 和 SMACK-4.2.4
我已经在PC中安装了 Spark ejabberd客户端，并且可以在其中创建聊天室。但是当我朗读下面的代码时，它会得到以下异常。我也在连接到同一局域网的Android模拟器和手机上进行了尝试。
SMACK错误：

Log.e("Group","Group created successfully");
try {
muc.create(getResourcepart(grp.getText()+"")).makeInstant();

此处 manager.isServiceEnabled 返回true。

答案 0 :(得分：1)
问题出在这里-
**MultiUserChat muc = manager.getMultiUserChat(
getEntityBareJid(SessionHolder.abstractXMPPConnection.getUser()+""));**
参数名称格式应
Group_Name@conference.HOST_NAME
i.e-myroom@conference.localhost
这对我有用。 ：）
