Get Unread Messages in a Conversation

The IMLib SDK supports retrieving unread messages from a specified conversation, enabling apps to jump to the first unread message or display all unread mentions.

RongCoreClient.getInstance().getTheFirstUnreadMessage(conversationType, targetId, new ResultCallback<Message>() {
        @Override
        public void onSuccess(Message message) {

        }

        public void onError(IRongCoreEnum.CoreErrorCode e) {

        }
 });
