通过官网下载的最新版sdk tools，惊讶地发现自17年3月后，非捆绑Android Studio的sdk下载不再提供GUI版sdk manager，变成了真CLI包。

为了推Android Studio，google你连脸都不要了，mmp不知当讲否

这还不算完事，在jdk和android sdk都折腾完毕后，尝试编译apk收到如下报错：

CommandInvokationFailure: Unable to list target platforms. Please make sure the android sdk path is correct. See the Console for more details.

C:/Program Files/Java/jdk1.8.0_121\bin\java.exe -Xmx2048M -Dcom.android.sdkmanager.toolsdir=“C:/Users/Administrator/AppData/Local/Android/Sdk\tools” -Dfile.encoding=UTF8 -jar “C:\Program Files\Unity\Editor\Data\PlaybackEngines\AndroidPlayer/Tools\sdktools.jar” - stderr[ Error:Invalid command android ] stdout[ ]

在确认环境配置没毛病后，疑点转向unity对sdk tools的检查上。鉴于google在这方面老搞事情，不得不考虑是不是应该尝试下老版本tools

先备份tools目录出去，将老版本tools目录替换上，问题解决
