public final class ChatStateManager
extends ExtensionManager

This class manages Chat State Notifications, which are used to communicate the status of a user in a chat session, thus indicating whether a chat partner is actively engaged in the chat, composing a message, temporarily paused, inactive, or gone. Chat states can be used in the context of a one-to-one chat session or a multi-user chat room.

Because the Chat State protocol is relatively simple, the primary purpose of this manager is to enable or disable the Chat State protocol for Service Discovery purposes.

Furthermore it ensures that every sent message has a chat state notification as required by XEP-0085.

Sending Chat States

Setting your own chat state can either be done in a one-to-one chat session or a group chat.

 ChatStateManager chatStateManager = xmppSession.getManager(ChatStateManager.class);
 chatStateManager.setChatState(ChatState.COMPOSING, chat);
 
 

Receiving Chat States

If you want to react to chat states of your chat partner(s), just check for chat state extension and deal with it accordingly.

 ChatState chatState = message.getExtension(ChatState.class);
 if (chatState == ChatState.COMPOSING) {
     // Contact is typing.
 } else if (chatState == ChatState.PAUSED) {
     // Contact has paused typing.
 }
