ohne Grund gestoppt dies die App zum Laufen zu bekommen.

Irgendeine Lösung dafür?

irgendeine Art von Fehler Es ist mit mindestens einem Ihrer Realm Modellklassen. War da nicht mehr zu dieser Fehlermeldung? – EpicPandaForce

@EpicPandaForce, aber ich habe nichts in meinem Klassenschema geändert, es funktionierte von der vorherigen Version, meinst du, dass einige Anmerkungen veraltet sind? – Loai

@EpicPandaForce gibt es nur diese Fehlermeldung in der Build – Loai

So nach Ihren Stack-Trace, 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) }

es sagt „wenn Sie eine Klasse, die mit RealmProxy endet“, die Sie do as per this question where you literally have a class named RealmProxy, dann versucht er seine Superklasse zu bekommen (was sollte RealmObject oder RealmModel sein), die es nicht haben, weil es nicht Teil des Realm ist Schema, so dass es null zurückgibt und der Transformator abstürzt.

Lösung 1: Ihre RealmProxy Klasse etwas umbenennen wie, RealmFacade oder etwas

oder

Lösung 2: einige zufällige Klasse mit RealmProxy erweitern, die nicht @RealmClass Anmerkung hat.

public abstract class RealmProxyBase { 
} 

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

(in der Zwischenzeit reichte ich ein Problem für sie here)

Vielen Dank meine Liebe, was mich überzeugt, dass mein Code ist in Ordnung, dass ich ** RealmProxy ** vorher in der vorherigen Version und es funktioniert problemlos, Any Wie danke und bereit für die Zukunft Frage: D – Loai

Nun ja, aber Realm hat den Realm-Transformer in 0.88.0 und höher hinzugefügt, und bisher ist noch niemand auf dieses NPE gestoßen. Dennoch ist "Lösung 2" ziemlich einfach, genau das würde ich tun. – EpicPandaForce
