org.jivesoftware.smackx.chatstates.ChatStateManager

public final class ChatStateManager
extends Manager

Handles chat state for all chats on a particular XMPPConnection. This class manages both the stanza extensions and the disco response necessary for compliance with XEP-0085. NOTE: getInstance(org.jivesoftware.smack.XMPPConnection) needs to be called in order for the listeners to be registered appropriately with the connection. If this does not occur you will not receive the update notifications.
