如何在RMD和ROS之间同步？

Question

例如，我想在RMD中使用CURD，然后同步到ROS 当它处于离线状态时，我可以用RMD获取数据 如何将整个RDM同步到ROS？ 这是我的代码：
SearchModel

RealmUtils.getInstance()
            .where(Book.class).equalTo("isbn13", isbn)
            .findAllAsync().<Book>asObservable()
            .subscribe(books -> apiListener.onSuccess(books.size() > 0),
                    throwable -> apiListener.onFailure(throwable.getMessage()));

InsertModel

RealmUtils.getInstance().asObservable()
            .subscribe(realm ->
            {
                Book book = realm.createObject(Book.class);
                book.isbn13 = bookInfoResponse.getIsbn13();
                book.title = bookInfoResponse.getTitle();
                book.subtitle = bookInfoResponse.getSubtitle();
                book.publisher = bookInfoResponse.getPublisher();
                book.authors = bookInfoResponse.getAuthors();
                book.translators = bookInfoResponse.getTranslators();
                book.pubdate = bookInfoResponse.getPubdate();
                book.pages = bookInfoResponse.getPages();
                book.origin_title = bookInfoResponse.getOrigin_title();
                book.image = bookInfoResponse.getImages().getLarge();
                book.summary = bookInfoResponse.getSummary();
                book.infoString = bookInfoResponse.getInfoString();

                apiListener.onSuccess(true);
            }, throwable -> apiListener.onFailure(throwable.getMessage()));

DeleteModel

RealmUtils.getInstance()
            .where(Book.class).equalTo("isbn13", isbn)
            .findAllAsync().<Book>asObservable()
            .subscribe(books ->
            {
                books.deleteAllFromRealm();
                apiListener.onSuccess(false);
            }, throwable -> apiListener.onFailure(throwable.getMessage()));

这会导致java.lang.IllegalArgumentException: Configurations cannot be different if used to open the same file. 那我该怎么办？
