3.总结问题：

初步估计下载AS的时候，AS把自动检测sdk并且把sdk信息更改了，导致unity使用sdk时版本不兼容，重新下了一个低版本的sdk单独给unity用，问题暂时解决

但自我感觉并未抓住问题核心，但迫于急需unity故暂用此方法解燃眉之急

4.解决方法：

4.1步骤一：下一个低版本的sdk

下载地址：AndroidDevTools - Android开发工具 Android SDK下载 Android Studio下载 Gradle下载 SDK Tools下载

##4.2 步骤二：将解压缩后的文件复制到原来的SDK的同级目录下

切记不要把原来的sdk删掉，既然原来的sdk在AS下能正常使用，那就让AS使用原来的sdk，新下载的androidsdk提供给unity使用

4.3步骤三:进入sdk Manager下载相关配置

下载之后是一个压缩包，将其解压到一个全英的路径下，双击SDK Manager可运行文件，打开下载各项依赖，具体要下写什么可详看此文章，照着搞就可：SDK Manager的使用 - 没有阳光天空也是素颜 - 博客园 (cnblogs.com)

按之前提到的那篇博客下载好后，androidsdk文件夹一共有23.8G，肯定有很多内容是不用下的，不过我也无法判断

4.4步骤四：更改unity中的sdk
