Adding Listeners for MultiUserChat (aSmack)

Question

How can we initialize MultiuserChat, these are the details, to create an object of MultiuserChat class we need the connection and room name as parameters // this is the constructor of MultiUserChat

  public MultiUserChat(Connection connection, String room) {
    this.connection = connection;
    this.room = room.toLowerCase();
    init();
}

its only applicable if we have a room ie. if we are inside a room. My question is if we are not inside the room, or we are not joined/created any rooms how can we initialize the MultiUserChat class. Because for adding listeners such as invitation rejection and addinvitationListener we need the object of the MultiUserChat.

eg. muc.addInvitationRejectionListener(new InvitationRejectionListener() {

            @Override
            public void invitationDeclined(String invitee, String reason) {
                Log.e("CHECK", "Invitation rejected, Inv- "+invitee+": Reas- "+reason);
                Toast.makeText(getApplicationContext()  , "Invtn REJECTED, invitee- "+invitee+" :reason-"+reason, 
                        Toast.LENGTH_LONG).show();

            }
        });

Answer 1

Your assumption is wrong. Creating a MultiUserChat instance does not make the client automatically join or create this MUC.

So simply create the instance and add the listeners.

Answer 2

You dont need an object of MultiUserChat for getting invitations. You can use below code.

MultiUserChat.addInvitationListener(conn3, new InvitationListener() {
public void invitationReceived(XMPPConnection conn, String room, String inviter,
String reason, String password) {

    // Reject the invitation

    MultiUserChat.decline(conn, room, inviter, "I'm busy right now");

    //Accept the invitation

    MultiUserChat muc=new MultiUserChat(conn,room);

    muc.join(testNickName,password);

}

}

For invitation rejection listener you need a MultiUserChat Object.
