我已更新至最新版本,希望能解決我的問題,但事實並非如此。我正在使用沒有任何工作。 Realm Migration [Android 1.2]
RealmConfiguration config = new RealmConfiguration.Builder(this)
.name("myrealm.realm")
.migration(new Migration())
.schemaVersion(2) // 2
.build();
try {
Realm realm = Realm.getInstance(config); // Automatically run migration if needed
realm.close();
} catch (Exception e) {
e.printStackTrace();
}
Realm.setDefaultConfiguration(config);
此代碼用於更新並添加一些新對象。這裏是我的移民
public class Migration implements RealmMigration {
@Override
public void migrate(final DynamicRealm realm, long oldVersion, long newVersion) {
// Access the Realm schema in order to create, modify or delete classes and their fields.
RealmSchema schema = realm.getSchema();
// Migrate from version 1 to version 2
if (oldVersion == 1) {
// Create a new classes
RealmObjectSchema styleSchema = schema.create("SavedStyle").addField("title", String.class).addField("json", String.class);
RealmObjectSchema dictSchema = schema.create("SavedDictionary").addField("title", String.class).addField("dictionary", String.class);
RealmObjectSchema journalSchema = schema.create("CustomJournal").addField("title", String.class).addField("json", String.class);
oldVersion++;
}
if (oldVersion < newVersion) {
throw new IllegalStateException(String.format("Migration missing from v%d to v%d", oldVersion, newVersion));
}
}
}
我得到的錯誤
java.lang.IllegalArgumentException: Configurations cannot be different if used to open the same file. The most likely cause is that equals() and hashCode() are not overridden in the migration class: otherClasses.Migration
如果只是想而不從以前的版本更新,即使運行它的獨立。不知道該做什麼。真的需要它的工作,所以我不必擦除每個人的數據。考慮製作更正式的錯誤報告,但想檢查是否有其他人知道是否有解決方案。每當我嘗試獲取默認配置時,都會發生此問題。它通常工作當我第一次打開應用程序,但是當我去到下一個活動
我就像你可能看到過的那樣,但你從來沒有反應過。我想這個問題並不重要。 – EpicPandaForce
