Unity打包APK报错 using a newer Android Gradle plugin to use compileSdk = 35_warning:we recommend using a newer android gradle


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

在这里插入图片描述
三个报错信息如下
第一个

WARNING:We recommend using a newer Android Gradle plugin to use compileSdk = 35This Android Gradle plugin (7.1.2) was tested up to compileSdk = 32This warning can be suppressed by adding android.suppressUnsupportedCompileSdk=35to this project\'s gradle.propertiesThe build will continue, but you are strongly encouraged to update your project touse a newer Android Gradle Plugin that has been tested with compileSdk = 35

第二个

第三个

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
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=/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
