How to know who received a message in a MUC room

Question

For my thesis, I am using Smack to log a XMPP network that uses the MUC module.

Another software is currently sending IoT sensor data into different MUC rooms.

I'd like to know for every message sent into a MUC room, which users were in that room at the time of the message. Is this possible? I could use a messageListener to every muc room, however the listener only receives a message as an argument. Therefore I could not know who is logged into the room inside the listener method.

you can get all muc message in StanzaListener in xmpp. Please follow few steps to done this

Step 1. Declare as a global variables

ChatManagerListener chatListener;
Chat chat;
StanzaListener packetListener;

Step 2. Use this code in oncreate or in fragment

Note: Make sure you have connected with chat server.

    packetListener = new StanzaListener() {
        @Override
        public void processPacket(Stanza packet) throws SmackException.NotConnectedException, InterruptedException {

            if (packet instanceof Message) {
                final Message message = (Message) packet;

               }
        }
    };

        XMPP.getInstance().getConnection(acitiviy)).addAsyncStanzaListener(stanzaListener, null);

    ServiceDiscoveryManager sdm = ServiceDiscoveryManager
        .getInstanceFor(XMPP.getInstance().getConnection(acitiviy)));
    sdm.addFeature("jabber.org/protocol/si");
    sdm.addFeature("http://jabber.org/protocol/si");
    sdm.addFeature("http://jabber.org/protocol/disco#info");
    sdm.addFeature("jabber:iq:privacy");

Step 3. Methods for one to one chat purposer

void sendMessage(String message) {
if (chat != null) {
    try {
        chat.sendMessage(message);
            Message msg = new Message();
            msg.setTo(JidCreate.bareFrom(jid));
            msg.setFrom(XMPP.getInstance().getConnection(acitiviy)
                    .getUser());

            ChatStateExtension ext = new ChatStateExtension(
                    ChatState.paused);
            msg.addExtension(ext);
            lastComposing = System.currentTimeMillis();
            chat.sendMessage(msg);

    } catch (SmackException.NotConnectedException e) {
    } catch (Exception e) {

    }
}

}

Step 4. On destroy XMPP.getInstance().getConnection(acitiviy)).removeAsyncStanzaListener(stanzaListener);

Hope this will help you and if you want more information take a look from here. Thankyou
