Unity打包APK报错 using a newer Android Gradle plugin to use compileSdk = 35

三个报错信息如下

第一个

bash 复制代码

WARNING:We recommend using a newer Android Gradle plugin to use compileSdk = 35

This Android Gradle plugin (7.1.2) was tested up to compileSdk = 32

This warning can be suppressed by adding
    android.suppressUnsupportedCompileSdk=35
to this project's gradle.properties

The build will continue, but you are strongly encouraged to update your project to
use a newer Android Gradle Plugin that has been tested with compileSdk = 35

第二个

bash 复制代码

错误原因：这个问题报错的原因是，我使用的 Unity2022.3.26，与之对应的 Android Gradle plugin 也就是 Gradle 版本是 7.1.2，这是Unity 官方给的对应关系

打包 APK 时配置Player Settings-> Android -> OthersSettings -> Identification -> Target API Level -> API Level 35

经测试 API Level 设置为 34/33/32 等低版本都是可以正常打包的

解决方案一

Unity 官方回答：这个问题影响Unity版本2021.3和2022.3 LTS。

目前，由于谷歌构建工具中AAPT2和SDK 35之间的兼容性错误，无法在Unity 2021.3和2022.3上构建SDK 35。我们已经向b谷歌报告了这个问题

我们正在Unity内提供修复，但与此同时，请遵循以下解决方案：

在 Unity 项目内打开 gradleTemplate.properties ，这个文件生成方式 Player Settings → Publish Settings → Check "Custom Gradle Properties Template" 在 Plugins/Android 文件夹下生成 gradleTemplate.properties 用文本编辑器打开，然后在最后添加一行 android.aapt2FromMavenOverride=<PATH_TO_YOUR_SDK>/build-tools/35.0.0/aapt2.exe

完整路径以Unity2022.3.26f1 为例安装路径 android.aapt2FromMavenOverride=2022.3.26f1/Editor\Data/PlaybackEngines/AndroidPlayer/SDK/build-tools/35.0.0/aapt2.exe

但是这个解决方案，我自己测试是无效的

解决方案二

错误原因中已经说了 API Level 设置低于 35 的都是可以正常打包的，那么如果不是必须要求设置为 35 那么就降低版本，再打包

解决方案三

升级 Unity 版本，经过测试 Unity6 打包 APK 设置 API Level 35 打包正常
