运行时异常：无法实例化应用程序 com.company.app.Application：ClassNotFoundException

如何解决运行时异常：无法实例化应用程序 com.company.app.Application：ClassNotFoundException

我在本网站上阅读了一些具有相同或类似错误消息的答案，并且我已经尝试了所有解决方案。遗憾的是，到目前为止，它们都没有奏效。

我的 gradle 文件看起来都像为 Multidex 正确设置，Application 类 extends MultiDexApplication 并在清单中正确引用，我已经清理了所有缓存并重新启动了 IDE，删除从项目和设备构建并重新构建/重新安装等

检查 APK，我在 Application 中找到了 classes2.dex，正确引用了 .super Landroidx/multidex/MultiDexApplication;

我得到的堆栈是这样的：

谁能弄清楚这是怎么回事？

解决方法

在模块级别 build.gradle，我们添加了以下几行：

// Near the top
apply plugin: 'com.google.firebase.crashlytics'

// ... 

android {

    // ...

    compileOptions {
        sourceCompatibility 1.8
        targetCompatibility 1.8
    }
    
    // ...
}

// ...

我不知道这是如何解决这个崩溃的，但我想这就是我使用“它可以正常工作”库的结果。
