Java 仅在我的电脑上的Android项目中ClassNotFoundException

最近，当我准备在家里用Windows8.1在我的电脑上完成我的工作时，我发现这个项目不能正常工作——它编译，在模拟器上运行，并在某个特定点崩溃（它在我的电脑上是100%可复制的）

然而，同样的存储库版本在Mac电脑和我的同事的Windows 10机器上都可以使用

提到的每个环境都使用Android Studio 2.3.1、gradle 3.3和Kotlin 1.1.1，并在API 25 x86_64映像上运行应用程序

该项目正在使用multidex 1.0.1库

发生崩溃是由于以下异常：

ActivityErrorHandlingExtensions.kt

几周前我遇到了类似的问题。下面是我为避免出现

ClassNotFoundException

而做的基本操作，在我的例子中，这是由于在更新androidstudio、gradle等之后的Multidex“配置”

将

compile'com.android.support:multidex:1.0.1'

添加到应用程序gradle文件中的依赖项列表中

移除

Multidex.install（此）onCreate（）

方法编写>并在应用程序类中添加以下内容：

@Override
protected void attachBaseContext(Context context) {
    super.attachBaseContext(context);
    MultiDex.install(this);
}

我在更新gradle版本等之后出现了错误，所以请确保所有内容都是最新的

---

希望有帮助。

我没有在

onCreate（）

中调用

Multidex.install（this）

，因为我的

App

类继承了

MultiDexApplication

类的这种行为（

attachBaseContext

已经在那里实现）。所以我只添加了覆盖（这可能是多余的）。不幸的是，这根本没有帮助。它仍然在

SomeActivity

中崩溃（这不是我的应用程序中启动的第一个，顺便说一句）。你能为问题活动发布“工具->Kotlin->显示Kotlin字节码”的输出吗？@VyacheslavGerasimov请查看更新。我已经发布了

getDataFor

字节码。如果您需要更多，请告诉我，因为我不想花一整天的时间混淆所有2.5k行字节码：）字节码中是否有名为

com/project/package/SomeActivityKt$sam$Action1$22181393

的类？我想应该为传递给subscribe方法的lambda生成它。根据我的理论，它可能是用错误的名称生成的。如果它的名称正确，请尝试重新安装android SDK，如果您还没有安装的话。也许构建工具有问题。@VyacheslavGerasimov没有这样的类。我在寻找任何包含

22181393

，

SomeActivityKt

或

sam

的内容，我在这里发布的片段中只有两个位置。这真的很奇怪，因为我可以在

AnotherActivity.kt

getData

中看到为代码生成的类似类：

最终类com/project/package/AnotherActivityKt$sam$Action1$1c16c27d实现了rx/functions/Action1

。所以我想它根本不是为

SomeActivity

生成的。有了这些信息，您认为重新安装SDK会有帮助吗？
