1. 安装SDK
下载Android
SDK Tools only（不包含ADT和其他包），目前最新版本是r21，双击安装或者下载zip包直接解压到指定目录即可。
2. 安装Eclipse ADT plugin
下载最新版ADT，ADT-21.0.0.zip，在Eclipse中，点击Help->install new software->add 将压缩包的路径添加到源，然后选中刚刚添加的源，勾选要安装的Developer Tools，取消勾选Contact all update sites during install，然后点next. 直到安装全部完成。

3. 重启Eclipse
在重启之后，会提示设置SDK的安装路径，或者提示SDK的安装不完全，点击确定启动Android SDK Manager,在看到图5所示的图像时，等待载入完成（Done loading packages），这样你会看到那些包还没有安装。
4. 完成离线安装
将安装第5节方法下载好的zip文件，全部复制到SDK安装目录根目录下的temp文件夹内，不要嵌套其他子文件夹。 然后勾选相应的要安装的包，即可瞬间完成安装，不必等待其缓慢的下载速度。

5. 原理
查看SDK Manager Log发现每次更新时，SDK Manager 都下载以下5个xml文件：
1 |
"http://dl-ssl.google.com/android/repository/repository-7.xml"; |
2 |
"http://dl-ssl.google.com/android/repository/addon.xml"; |
3 |
"http://software.intel.com/sites/landingpage/android/addon.xml"; |
4 |
"http://www.mips.com/global/sdk-sys-img.xml"; |
5 |
"http://download-software.intel.com/sites/landingpage/android/sys-img.xml"; |
编写一个简单程序，将其中的名为url的标签对应的内容，拼接在路径http://dl-ssl.google.com/android/repository/后面，即可得到所有需要的安装包的下载地址，然后可以用迅雷等下载工具进行下载，将下载好的包拷贝到SDK根目录下的temp文件夹内，再点安装时，即可直接安装，节省大量时间。（在天朝安装这些包，之有几KB的下载速度）

用迅雷下载完成后，把相应的zip包放到sdk/temp目录下。再次打开SDK Manager.exe，勾选相应的sdk进行安装。完成离线安装
