Question

当用户从1到3 db架构升级

时，我遇到异常

领域配置如下：

    RealmConfiguration realmConfiguration = new RealmConfiguration.Builder()
            .name(AppConstants.DB_NAME)
            .schemaVersion(schemaVersion)
            .build();
    try {
        Realm.migrateRealm(realmConfiguration, new DBMigration()));
    } catch (Exception ignored) {
        // If the Realm file doesn't exist, just ignore.
    }
    Realm.setDefaultConfiguration(realmConfiguration);

我已在代码中指定了数据库迁移，其中我提到了所有数据库更改。

我正在使用领域版本3.3.0

您能帮忙解决这个问题吗？提前谢谢。

由io.realm.exceptions.RealmMigrationNeededException引起的android
