mac上unity2017设置Android打包

识字粗堪供赋役，不须辛苦慕公卿。这篇文章主要讲述mac上unity2017设置Android打包相关的知识，希望能为你提供帮助。
1. 下载android SDK：通过下载Android Studio进行安装，但是下载Android Studio 3.6.1版本后，SDK Manage有变化。Unity打包需要的SDK Tools被Obsolete了，需要把Hide Obsolete Packages的勾选去掉才能看到。

2. 安装SDK Build-Tools 30-rc1之后，/Users/xxx/Library/Android/sdk/build-tools目录下，30-rc1的目录名称是30.0.0-rc1，会导致Unity打包会报错。

有两种解决方法：
解决方法1：把 30.0.0-rc1 目录改名为 30.0.0就可以
【mac上unity2017设置Android打包】 解决方法2：修改 Unity安装目录下的文件 /PlaybackEngines/AndroidPlayer/Tools/GradleTemplates/mainTemplate.gradle，改成其他版本的。
