void io.agora.chat.ChatManager.ackConversationRead ( String conversationId ) throws ChatException

Sends the conversation read receipt to the server.

This method is only for one-to-one chat conversations.

This method will inform the sever to set the unread message count of the conversation to 0. The message sender will receive the ConversationListener#onConversationRead(String, String) callback. The message recipient that has logged in to multiple devices, will also receive the callback.

If you want to send a read receipt for a group message, call ackGroupMessageRead(String, String, String).

Parameters

conversationId The conversation ID.

Exceptions

ChatException The possible exceptions are as follows: Error#USER_NOT_LOGIN, Error#SERVER_NOT_REACHABLE, and Error#MESSAGE_INVALID. See Error.

		String	ext ) throws ChatException

Sends the read receipt for a group message to the server.

Note

You can only call this method after setting ChatOptions#setRequireAck(boolean) and ChatMessage#setIsNeedGroupAck(boolean) to true.

To send the read recipient for a one-to-one chat message to the server, call ackMessageRead(String, String).

To send the conversation read receipt to the server, call ackConversationRead(String).

Parameters
