Без какой-либо причины это остановило приложение, чтобы получить работу.

Любое решение для этого?

Там какая-то ошибка, по крайней мере, один из ваших классов моделей Realm. Не было ли этого сообщения об ошибке? – EpicPandaForce

@EpicPandaForce, но я ничего не меняю в своей схеме классов, она работает с предыдущей версией, вы имеете в виду, что некоторые аннотации устарели? – Loai

@EpicPandaForce есть только сообщение об ошибке в сборке – Loai

Так в соответствии с вашими трассировки стека, this line fails in the Realm-Transformer:

def allModelClasses = allClassNames

.findAll { it.endsWith('RealmProxy') }

.collect { classPool.getCtClass(it).superclass }

.findAll { it.hasAnnotation(RealmClass.class) || it.superclass.hasAnnotation(RealmClass.class) }

Так он говорит: «Если у вас есть класс, который заканчивается RealmProxy», который вы do as per this question where you literally have a class named RealmProxy, то он пытается получить его суперкласс (который должен быть RealmObject или RealmModel), которые он не имеет, потому что это не является частью Королевства схема, поэтому он возвращает null и сбой трансформатора.

Решение 1: переименовать RealmProxy класс что-то подобное, или что-то RealmFacade

или

Решение 2: расширить некоторый случайный класс с RealmProxy, который не имеет @RealmClass аннотацию.

public abstract class RealmProxyBase { 
} 

public class RealmProxy extends RealmProxyBase implements Closeable { 
    // ...

(в то же время, я подал вопрос для него here)

Большое спасибо, мой дорогой, что заставляет меня уверен, что мой код в порядке, что у меня есть ** RealmProxy ** До этого в предыдущей версии, и он отлично работает без каких-либо проблем, Any Как спасибо вам и буду готов к будущему Вопрос: D – Loai

Ну да, но Realm добавил Realm-Transformer в 0.88.0 и выше, и никто раньше не сталкивался с этим NPE раньше. Тем не менее, «решение 2» довольно просто, вот что я сделал бы. – EpicPandaForce
