我使用ejabberd作为xmpp服务器和aSmack API在Android中创建聊天多用户聊天
我正在使用以下代码
public boolean createGroup(XMPPConnection connection, String groupName) {
/*
* if (connection == null) return false; try {
* connection.getRoster().createGroup(groupName);
* Log.v("Group created : ", groupName); return true; } catch (Exception
* e) { e.printStackTrace(); return false; }
*/
if (getConnection() == null) {
try {
connect();
} catch (XMPPException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
//configure(ProviderManager.getInstance());
SmackAndroid.init(getApplicationContext());
MultiUserChat muc = new MultiUserChat(getConnection(),
"chitchat@conference.folksv.com");
try {
muc.create("chitchat");
Form form = muc.getConfigurationForm();
Form submitForm = form.createAnswerForm();
for (Iterator<FormField> fields = form.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>();
// Log.i(TAG, "list of owners=====" +owners.toString());
owners.add("akash");
submitForm.setAnswer("muc#roomconfig_roomowners", owners);
muc.sendConfigurationForm(submitForm);
} catch (XMPPException e) {
e.printStackTrace();
}
return true;

但我收到了以下错误

我无法理解我所缺少的内容以及此消息的含义。
答案 0 :(得分：1)
问题在于以下代码行
submitForm.setAnswer("muc#roomconfig_roomowners", owners);
删除它让我的房间创建工作。
