Unity Android 构建失败：指定的可执行文件不是此 OS 平台的有效应用程序答案

【问题标题】：Unity Android build failure: The specified executable is not a valid application for this OS platformUnity Android 构建失败：指定的可执行文件不是此 OS 平台的有效应用程序
【发布时间】：2019-10-26 06:34:14
【问题描述】：

在最后一步为 Android 失败构建 Unity 项目，这是我在控制台中得到的：

Failed running C:\Program Files\Unity\Hub\Editor\2019.2.4f1\Editor\Data\il2cpp/build/il2cpp.exe ... il2cpp.exe didn't catch exception: System.AggregateException: One or more errors occurred. ---> System.ComponentModel.Win32Exception: The specified executable is not a valid application for this OS platform.

如何了解问题所在并解决问题？

完整的错误文本：

【问题讨论】：

你的 NDK 版本是多少？
Pkg.Revision = 16.1.4479499 来自 source.properties 文件。一切都通过 Unity Hub 安装。

标签： android windows unity3d build-error

【解决方案1】：

内置unity ndk本身有bug，需要从google android开发者页面安装稳定版：Android NDK, Revision 16b (December 2017)。

【讨论】：

我下载并解压到一个文件夹中。然后在 Unity -> Preferences -> External tools 中关闭 "Android NDK Installed with my Unity" 复选框并选择下载文件夹的路径。它没有帮助，错误消息仍然相同。
@Sergey，那么这是 unity 本身的一个 bug，尝试升级到最新的稳定版本。
有几个人在做这个项目，但我是唯一遇到这个问题的人。他们不会同意更改版本。
@Sergey 你有没有尝试编译一个统一的默认空项目？
我设法以稍微不同的方式解决了这个问题。非常感谢您的帮助！

【解决方案2】：

我尝试安装/重新安装所有类型的 android 工具、Unity 编辑器、Visual Studio（但我没有尝试重新安装 Windows :)。最后，为了解决另一个问题，我尝试更改Edit -> Project Settings -> Player -> Other Settings -> Configuration -> Scripting Backed，它从IL2CCP 更改为Mono，它解决了我的构建错误（并且构建过程变得更快）。

我仍然不知道为什么我是项目团队中唯一一个在选择IL2CCP时必须处理这个问题的人，但至少现在我可以调试项目了。

如果您对和这里有什么区别感兴趣，这里是good answers 关于这个话题。
