Question

当我将realm.io库添加到我的Android应用程序并尝试运行应用程序时，我在编译期间收到此错误：

错误：任务＆＃39;：compileDebugJava＆＃39;执行失败。＆GT; java.lang.ClassCastException：com.sun.tools.javac.code.Symbol $ ClassSymbol无法强制转换为javax.lang.model.element.PackageElement

这是我的build.gradle：

buildscript {
repositories {
    mavenCentral()
    maven { url 'http://download.crashlytics.com/maven' }

当我删除领域依赖项和代码时，应用程序编译正常。我正在运行Android Studio 0.8.14

Answer 1

问题原来是我的领域模型是嵌套类，而不是顶级类。改变这个解决了这个问题。

Answer 2

您的模型中的字段没有正确的getter和setter。

无法使用领域编译Android应用程序
