Sending message does not work in XMPP with Smack library

Problem Description

I'm writing chat application using XMPP and Smack Android library. I'm sending messages using code below and everything is working fine.

final ChatManager chatManager = ChatManager.getInstanceFor(connection);
chatManager.addChatListener(this); 
....

@Override
public void chatCreated(Chat chat, boolean createdLocally) {
    chat.addMessageListener(this);
}

@Override
public void processMessage(Chat chat, Message message) {
    // Do something here.
}

Chat chat = ChatManager.getInstanceFor(connection).createChat(jid);
chat.sendMessage("message");

Question

Unfortunately the API above is deprecated org.jivesoftware.smack.chat.Chat and instead I should use org.jivesoftware.smack.chat2.Chat, so I am changing implementation as follows

final ChatManager chatManager = ChatManager.getInstanceFor(connection);
chatManager.addOutgoingListener(this);
chatManager.addIncomingListener(this);
....
Chat chat = ChatManager.getInstanceFor(connection).chatWith(jid);
chat.send("message");

In this case I can still get Incoming messages, but when I am trying to send message with chat.send("message"); server does not get anything and addOutgoingListener callback is not called.

Any ideas why?

You can refer to this code snippet:

public void sendMessage(String to, Message newMessage) {
if(chatManager!=null) {
Chat newChat = chatManager.createChat(to);

try {
if (connection.isConnected() && connection.isAuthenticated()) {

newChat.sendMessage(newMessage);
}
} catch (SmackException.NotConnectedException e) {
e.printStackTrace();
}
}
else
{
Log.d(TAG,”chatmanager is null”);
}
}

Digging a bit deeper I found the answer, the code below will help to send a message

Sending Message Code

final Chat chat = ChatManager.getInstanceFor(connection).chatWith(jid);

Message newMessage = new Message(jid, Message.Type.chat);
newMessage.setBody(message);

chat.send(newMessage);

Conclusion

So instead of sending a string message, you need to create a Message object and I think what is more important is to specify Message.Type.chat in the constructor and also jid and then call chat.send(...)

There is an example with an older version of smack:

import org.jivesoftware.smack.Chat;
import org.jivesoftware.smack.ChatManager;
import org.jivesoftware.smack.ChatManagerListener;
import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.MessageListener;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;
import org.jivesoftware.smack.packet.Message;

public class Test {
    public static void main(String args[]) throws XMPPException {
        ConnectionConfiguration config = new ConnectionConfiguration("127.0.0.1", 5222);    
        XMPPConnection connection = new XMPPConnection(config); 
        connection.connect();   
        connection.login("userx", "123456");
        ChatManager cm = connection.getChatManager(); 
        Chat chat = cm.createChat("tongqian@tsw-PC", null);
        /*
         * add listener
         */
        cm.addChatListener(new ChatManagerListener() {
            @Override
            public void chatCreated(Chat chat, boolean create) {
                chat.addMessageListener(new MessageListener() {
                    @Override
                    public void processMessage(Chat chat, Message msg) {
                        System.out.println(chat.getParticipant() + ":" + msg.getBody());
                    }
                });
            }
        });
        chat.sendMessage("hello");  
        while(true);        
        //connection.disconnect();  
    }
}
