Mark a conversation as read

After the user has opened and read visible messages, call messageManager.markConversationMessageAsRead() to mark the conversation as read. Do not mark a conversation read merely because a notification was previewed or a message arrived in the background.

OpenIMClient.getInstance().messageManager.markConversationMessageAsRead(
    conversationID,
    new OnBase<String>() {
        @Override
        public void onSuccess(String data) {
            // The request completed.
        }

        @Override
        public void onError(int code, String error) {
            // code and error describe the failure.
        }
    }
);

The callback indicates that the mark-as-read request has completed. To update the conversation list, query conversations again or receive changes through onConversationChanged.

For one-to-one chats, listen for read receipts from the peer through OnAdvanceMsgListener.onRecvC2CReadReceipt. See Receive messages for the message listener setup and Message overview for message callbacks and read-receipt fields.
