命令行下载升级Android SDK

最近应该在服务器上用Jenkins自动打包Android app，从google官方上下载的Linux版本sdk结果看到上面就只有一个tools目录有文件，其他的都没有。。。

无奈，服务器是没有界面的，之前都习惯用IDE去调试升级，现在尝试用命令行下载更新了。

从google的官方下载最新Linux版本SDKlinux调用android sdk，由于dl.google.com域名一直没有被墙linux调用android sdk，所以才可以直接从官方下了。这点不错~

$ wget https://dl.google.com/android/android-sdk_r24.4.1-linux.tgz
解压
$ tar zxvf android-sdk_r24.4.1-linux.tgz

前面说到了，我们下载的这个包貌似只有tools目录下才有东西。既然google给了我们这个，表示这上面显然有可以升级SDK的软件啦。

其实就是tools/android这个文件

$ cd android-sdk-linux/tools
