java - Android 意外的顶级异常和验证错误

Question

我正在尝试组合一个 Android 应用程序，该应用程序使用一个使用 IKVM 的库，因此我需要包含 mscorlib.jar。问题是这样的。当我将 mscorlib.jar 添加为模块依赖项(使用 Intellij)时，我收到下面的意外顶级异常，该异常来自此处的帖子 Android Studio - UNEXPECTED TOP-LEVEL EXCEPTION:意味着该库被多次包含。

如果我删除它，项目会编译，但当应用程序的部分实际调用使用 IKVM 的库时，我会在运行时收到验证错误(如下)。它表示找不到 mscorlib.jar 中定义的异常处理程序。

因此，第一个错误似乎包含了两次 mscorlib.jar，但第二个错误则表明它根本不包含在内。我倾向于第一个错误不是由于包含两次而导致的，因为我一生都找不到它在除了它所属的模块依赖项之外的任何地方列为依赖项或库。

有人遇到过这种情况吗？

关于android sdk级别

  <uses-sdk
        android:minSdkVersion="9"
        android:targetSdkVersion="19" />

检查 androidManifest 中的 sdk 级别和 ide API 级别。
