public final class ChatManager
extends Manager

This class manages one-to-one chat sessions, which are described in 5.1. One-to-One Chat Sessions and XEP-0201: Best Practices for Message Threads.

Creating a new chat session

 ChatSession chatSession = xmppSession.getManager(ChatManager.class).createChatSession(chatPartner);
 

Listen for new chat sessions

When a contact initiates a new chat session with you, you can listen for it with the ChatSessionListener. The listener will be called either if you created the session programmatically as shown above, or if it is created by a contact, i.e. because he or she sent you a chat message.

You should add a MessageListener to the chat session in order to listen for messages.

 xmppSession.getManager(ChatManager.class).addChatSessionListener(new ChatSessionListener() {
     @Override
     public void chatSessionCreated(ChatSessionEvent chatSessionEvent) {
         ChatSession chatSession = chatSessionEvent.getChatSession();
         chatSession.addInboundMessageListener(new MessageListener() {
             @Override
             public void handleMessage(MessageEvent e) {
                 Message message = e.getMessage();
             }
         });
     }
 });
