推荐答案

Android SDK中被安装到C：/用户/用户/应用程序数据/本地/安卓/ SDK2 SDK工具目录中缺少这意味着Android的SDK需要一个文件夹中的工具，其中安装此SDK。但是，工具文件夹中并没有得到安装。可能是由于较低的存储。

"Android SDK was installed to: C: / Users / user / AppData / Local / android / SDK2 SDK tools directory is missing " It means the Android SDK requires a folder "tools", where this SDK was installed. But that "Tools" folder did not get installed. Probably due to low storage.

[解决] ：卸载Android SDK和重新安装。这一次，只是确保你有 ATLEAST 5GB （虽然3.2GB就足够了）自由空间，你永远要安装此SDK。一旦安装完成，只检查是否工具文件夹有否（在要安装SDK中的位置）

[SOLUTION] : Uninstall the Android SDK and install it again. This time just make sure that you have ATLEAST 5GB (though 3.2gb would be enough) free space where ever you are going to install this SDK. Once the installation is complete, just check whether "tools" folder is there or not (At the location where you are installing the SDK)
