Not able to receive group message using smack

问题:

 var multiUserManager: MultiUserChatManager = MultiUserChatManager.getInstanceFor(constants.obj.connection)
        var multiUserChat: MultiUserChat =multiUserManager.getMultiUserChat(JidCreate.entityBareFrom(roomName))

         var a: Resourcepart = Resourcepart.from(PreferenceManager.getDefaultSharedPreferences(applicationContext).getString("j_id", null))
         multiUserChat.join(a)

       multiUserChat.addMessageListener { object: MessageListener {
           override fun processMessage(message: Message?) {
               Log.v("Message is ",message.toString())
               Log.v("Message from ",message!!.from.toString())
               Log.v("Message is ",message.getBody())
               Log.v("Message subject ",message.getSubject())
               Log.v("Message is ",message.body)
           }

       } }

and I have try this also.

 multiUserChat.addMessageListener { GroupChatListener() }

 class GroupChatListener : StanzaListener {
    override fun processStanza(packet: Stanza?) {

        Log.v("Packet is ",packet.toString())
        Log.v("From",packet!!.from.toString())
        Log.v("Stanza id ",packet.stanzaId)
    }

I am not able to receive the message when anyone sent on the server but i am able to send the message.

edit:

This is the output I am getting when I press join button. I am not getting any error in the logcat.

multiUserChat?.addMessageListener {
                    Log.v("listener","yup")
                    MessageListener { message ->
                        Log.v("Message is complete ",message.toString())
                        Log.v("Message from ",message?.from.toString())
                        Log.v("Message is body",message?.getBody())
                        Log.v("Message subject ",message?.getSubject())
                        Log.v("Message body ",message?.body)
                    }
                }

Whenever someone send me the message Log.v("listener","yup") called. But don't go inside messagelistener. I have read the log output and find them I am getting the msg in the form of xml.

What I did:

First Join in to the GroupChat, then create a custom listener to get the missed messages and on the onSuccess add the messageListener. That is provide me the history messages in a List<> and after that the app start listen the new Message coming from this GroupChat.

public void joinToGroupChat(final MultiUserChat multiUserChat, final OpenFireListener<List<Message>> listener) {

    if (!multiUserChat.isJoined()) {
       multiUserChat.join(connection.getUser().getResourcepart());
    }

    getPendingMessages(multiUserChat, new OpenFireListener<List<Message>>() {
        @Override
        public void onSuccess(List<Message> result) {
            multiUserChat.addMessageListener(messageListener);
            listener.onSuccess(result);
        }

        @Override
        public void onError(String message) {
            listener.onError(message);
        }
    });
}

private MessageListener messageListener = new MessageListener() {
    @Override
    public void processMessage(Message message) {
        //I only use the subject and body in my project
        listener.notifyMessage(message.getSubject(), message.getBody());
    }
};

Make sure that you are joined into the GroupChat in the same context and implemented your custom listener. This is my generic implementation.

public interface OpenFireListener<T>{
    void onSuccess(T result);
    void onError(String message);
}

public interface OpenFireServerListener {
    enum STATE {ERROR, CONNECTION_CLOSED, RECONNECTION_SUCCESS, RECONNECTION_FAILED, AUTHENTICATED, NOT_AUTHORIZED, CONNECTED}

    void notifyStatusOpenFireServer(STATE state, String message);
    void notifyMessage(String streamName, String streamId);

}
