使用 IL2CPP 在 Unity 中构建 Android App Bundle 的错误和失败答案

【问题标题】：Errors and failure building Android App Bundle in Unity with IL2CPP使用 IL2CPP 在 Unity 中构建 Android App Bundle 的错误和失败
【发布时间】：2020-02-13 07:56:06
【问题描述】：

我正在尝试将我的 Unity3D 应用程序构建为 .aab，因为 Android Play 商店现在需要它来进行新提交。不幸的是，我收到错误并且每次构建都失败。我正在使用 Unity 编辑器版本 2018.4.11f1 LTS 和 NDK 版本 r16b。非常感谢任何帮助！

这是编辑器中记录的两个错误：

运行 C:\Program Files\Unity\Hub\Editor\2018.4.11f1\Editor\Data\il2cpp/build/il2cpp.exe 失败 -- 转换为 cpp --emit-null-checks --enable-array-bounds-check --dotnetprofile="unityaot" --compile-cpp --libil2cpp-static --platform="Android" --architecture="ARMv7" --configuration="Release" --outputpath="D:\workflow\Temp\ StagingArea\assets\bin\Data\Native\armeabi-v7a\libil2cpp.so" --cachedirectory="D:\workflow\Assets..\Library\il2cpp_android_armeabi-v7a/il2cpp_cache" --additional-include-directories="C:\Program Files\Unity\Hub\Editor\2018.4.11f1\Editor\Data\PlaybackEngines\AndroidPlayer/Tools\bdwgc/include" --additional-include-directories="C:\Program Files\Unity\Hub\Editor\2018.4.11f1\Editor\Data\PlaybackEngines\AndroidPlayer/Tools\libil2cpp/include" --tool-chain-path="C:/Users/seadn/AppData/Local/Android/Ndk/android-ndk-r16b" --map-file-parser="C:\Program Files\Unity\Hub\Editor\2018.4.11f1\Editor\Data\Tools\MapFileParser\MapFileParser.exe" --directory="D:\workflow\Temp\StagingArea\assets\bin\Data\Managed" --generatedcppdir="D:\workflow\Temp\StagingArea\Il2Cpp\il2cppOutput"

【问题讨论】：

标签： c# android unity3d android-ndk il2cpp

【解决方案1】：

未定义的引用指的是 Unity 项目中不支持 IL2CPP 的 WebRTC 插件。我将插件更新为支持 IL2CPP 的较新版本并成功构建了 .aab 文件。

【讨论】：

奇怪的是，虽然我有一个成功的 .aab 文件，但当我将它上传到 Play 控制台时，它说它不包含任何 64 位代码，尽管我检查了 ARM64 目标架构！
