how to create persistent muc room in smack 4.1 beta2

migrated from asmack to smack 4.1 beta2. The muc rooms created are no longer persistent.

MultiUserChatManager mucm=MultiUserChatManager.getInstanceFor(connection);
muc=mucm.getMultiUserChat(groupid+"@conference.localhost");
DiscussionHistory histroy=new DiscussionHistory();
histroy.setMaxStanzas(10);
muc.createOrJoin(username,null,histroy,SmackConfiguration.getDefaultPacketReplyTimeout());
muc.nextMessage();

when created with gajim, the rooms are persistent.

EDIT : Here is code we used earlier. By default the chat rooms were persistent,

muc = new MultiUserChat(connection, groupid+"@conference.localhost");

if(!muc.isJoined())
{
DiscussionHistory histroy=new DiscussionHistory();
histroy.setMaxStanzas(10);
muc.join(username,null,histroy,SmackConfiguration.getDefaultPacketReplyTimeout());
muc.nextMessage(0);
}

How did you previously create persistent rooms? I think you need to send the correct data forum using MultiUserChat.create to create a persistent room. – Flow
Hello @flow pls check the edited question. – Vignesh

You need to submit form like this for making a persistent group:

private void setConfig(MultiUserChat multiUserChat) {
    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());
            }
        }
        submitForm.setAnswer("muc#roomconfig_publicroom", true);
        submitForm.setAnswer("muc#roomconfig_persistentroom", true);
        multiUserChat.sendConfigurationForm(submitForm);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

You need to set muc#roomconfig_persistentroom to true in the MUC configuration from when creating the room.

MultiuserChat muc = manager.getMultiUserChat("[email protected]");
muc.create("myNick");
// room is now created by locked
Form form = muc.getConfigurationForm();
Form answerForm = form.createAnswerForm();
answerForm.setAnswer("muc#roomconfig_persistentroom", true);
muc.sendConfigurationForm(answerForm);
// sending the configuration form unlocks the room

Note that not all XMPP MUC services support persistent rooms. For more information see:

        multiUserChatManager = MultiUserChatManager.getInstanceFor(connection);

        multiUserChat = multiUserChatManager.getMultiUserChat(JidCreate.entityBareFrom(roomJID));

        multiUserChat.create(Resourcepart.from(nickname));

        Form form = multiUserChat.getConfigurationForm();
        Form submitForm = form.createAnswerForm();
        submitForm.getField("muc#roomconfig_enablelogging").addValue("1");
        submitForm.getField("x-muc#roomconfig_reservednick").addValue("0");
        submitForm.getField("x-muc#roomconfig_canchangenick").addValue("0");
        submitForm.getField("x-muc#roomconfig_registration").addValue("0");
        submitForm.getField("muc#roomconfig_passwordprotectedroom").addValue("0");
        submitForm.getField("muc#roomconfig_roomname").addValue(roomName);
        submitForm.getField("muc#roomconfig_whois").addValue("participants");
        submitForm.getField("muc#roomconfig_membersonly").addValue("1");
        submitForm.getField("muc#roomconfig_persistentroom").addValue("1");
        multiUserChat.sendConfigurationForm(submitForm);

This is how you can send the room configuration from and configure room. For more Details please see question. How to send room configuration form and create persistce rooms from android using smack 4.3.4
