该文章介绍下如何在linux中配置android sdk
一、下载android sdk
下载SDK，下载地址：http://developer.android.com/sdk/index.html，选择Linux(i386)。因为SDK只有32位的，如果装的是64位系统，则要安装ia32-libs，运行32位程序。安装命令：sudo apt-get install ia32-libs（在Ubuntu中的命令）。下载完成后解压，在终端进入到SDK的根目录，然后执行：tools/android update sdk –no-ui即可开始和windows里面一样的更新。
[root@app-server1 tools]# android update sdk --no-ui

………（下面省略）………
上面更新的过程中一些特殊的SDK是需要用户名和密码的，如：摩托罗拉和HTC。
我们到这些官网注册一下即可，摩托罗拉和HTC的网址：
注册官网：http://htcdev.com/ 这个是HTC的；具体的注册过程我就不多说了，要是看不懂的大家直接在线翻译一下就可以了
另外一个：https://developer.motorola.com/ 这个是MOTO的，也是一样的需要注册一下，方法同上面的HTC的一样
二、配置环境变量
更新完成后配置环境变量。使用命令 vi /etc/profile 编辑文件profile，然后在下面增加下面内容：
export ANDROID_HOME=/opt/softwaretools/android-sdk-linux
export PATH=$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools:$PATH
/opt/softwaretools/android-sdk-linux为SDK的根目录。
这个配置之后，以后要执行android里面的命令，就不是需要进到这个目录，直接可以在终端里面输入。
修改完成后，使用命令 :wq! 保存关闭文件，再执行命令 source /etc/profile 使配置生效一下。
在终端输入：android，如果Android SDK Manager窗口出来了，就证明环境配置成功。
