Track the total unread count

getTotalUnreadMsgCount() returns the complete unread snapshot for the signed-in account. Do not sum unreadCount values from only the currently loaded conversation pages.

OpenIMClient.getInstance().conversationManager.getTotalUnreadMsgCount(
    new OnBase<String>() {
        @Override
        public void onSuccess(String value) {
            int totalUnread = Integer.parseInt(value);
            updateApplicationBadge(totalUnread);
        }

        @Override
        public void onError(int code, String error) {
            recordTotalUnreadFailure(code, error);
        }
    }
);

The callback value is a String; handle parse failures as an application error rather than treating it as a partial list total. This page owns OnConversationListener.onTotalUnreadMessageCountChanged(int count), which updates the application badge after the initial query.
