create a group chat functionality in android and getting No response from server.. on muc.create()

问题

I am able to do one to one chat through ejabbered. server setup on local successfully between devices using my Ip on wifi. But when creating a group chat as

 MultiUserChat muc = new MultiUserChat(conn1, "myroom@conference.jabber.org");
 muc.create("testbot");

On searching I found muc.create() has problems and use muc.join() instead. But i want to create d room first. I am not sure problem is on server side or client side

I found the solution myself. Dere were no issues in smack library instead the configure settings were missing. Copy and paste below method and call it in when logging in.

public static void configure(ProviderManager pm) {

    // Private Data Storage

    pm.addIQProvider("query", "jabber:iq:private",
            new PrivateDataManager.PrivateDataIQProvider());

    // Time

    try {

        pm.addIQProvider("query", "jabber:iq:time",
                Class.forName("org.jivesoftware.smackx.packet.Time"));

    } catch (ClassNotFoundException e) {

        Log.w("TestClient",
                "Can't load class for org.jivesoftware.smackx.packet.Time");

    }

    // Roster Exchange

    pm.addExtensionProvider("x", "jabber:x:roster",
            new RosterExchangeProvider());

    // Message Events

    pm.addExtensionProvider("x", "jabber:x:event",
            new MessageEventProvider());

    // Chat State

    pm.addExtensionProvider("active",
            "http://jabber.org/protocol/chatstates",
