我只是试图将Realm数据库从0.86升级到2.1版本。无法在空对象上调用方法hasAnnotation（）

但面对这个错误随着Android的工作室

Error:Execution failed for task ':app:transformClassesWithRealmTransformerForDebug'. 
> Cannot invoke method hasAnnotation() on null object

有某种错误的与你的境界模型类的至少一个。这个错误信息没有更多吗？ – EpicPandaForce

@EpicPandaForce但我没有改变我的类架构中的任何东西，它是从以前的版本开始工作的，你的意思是一些注释已被弃用？ – Loai

@EpicPandaForce只有此错误消息在构建 – Loai

所以要根据您的堆栈跟踪，this line fails in the Realm-Transformer：

def allModelClasses = allClassNames

​​

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

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

所以它说：“如果你有与RealmProxy结尾的类”你do as per this question where you literally have a class named RealmProxy，然后它会尝试获取它的父（这应该是RealmObject或RealmModel），它并没有因为它不是王国的一部分架构，所以它返回null和变压器崩溃。

解决方案1：你RealmProxy类重命名为类似，RealmFacade什么

或

解决方案2：与RealmProxy不具有@RealmClass注释延长一些随机类。

public abstract class RealmProxyBase { 
} 

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

（在此期间，我提交了问题，它here）

非常感谢你亲爱的，是什么让我确信我的代码是好的，我有** RealmProxy **之前在以前的版本，它工作正常没有任何问题，任何如何感谢你，并准备好未来问题：D – Loai

是的，但Realm在0.88.0及以上版本中添加了Realm-Transformer，之前没有其他人遇到过这个NPE。不过，'解决方案2'相当简单，那就是我所要做的。 – EpicPandaForce
