用户在我的应用程序中遇到崩溃，我无法自行复制

我得到以下stacktrace：

在我改变执行Realm迁移的方式之前，这个问题才开始发生。以下是我的SplashActivity中发生的迁移代码：

RealmConfiguration realmConfig = new RealmConfiguration.Builder().schemaVersion(4).migration(new SchemaMigration()).build();
        try (DynamicRealm dynamicRealm = DynamicRealm.getInstance(realmConfig)) {

            if (dynamicRealm.getVersion() != -1 && dynamicRealm.getVersion() < CURRENT_SCHEMA_VERSION) {
                //show progress indicator
                showProgressDialog();

                Completable.fromAction(() -> Realm.migrateRealm(realmConfig))
                        .subscribeOn(Schedulers.io())
                        .observeOn(AndroidSchedulers.mainThread())
                        .subscribe(() -> {
                            progressDialog.dismiss();
                            Realm.setDefaultConfiguration(realmConfig);
                        });

            } else {
                Realm.setDefaultConfiguration(realmConfig);
            }
        }

我的应用程序中的各种活动引发了异常。迁移肯定会成功完成，SplashActivity会在访问Realm的任何其他活动开始之前完成。我只通过调用：

访问任何其他活动中的领域实例

Realm realm = Realm.getDefaultInstance();

有谁知道为什么以上会导致这个问题？我的第一个想法是我需要在设置默认配置之前关闭DynamicRealm实例。

java.lang.IllegalArgumentException：磁盘上的Realm比指定的更新：v4与v0
