(1)在http://java.sun.com/javase/downloads/index.jsp下载JDK6，安装JDK，省略。安装完毕后，设置环境变量JAVA_HOME为jdk的安装目录，并且将%JAVA_HOME%/bin添加到系统Path变量中。
(2)下载Android SDK并配置。
可以到http://developer.android.com/sdk/index.html上下载android-sdk_r06-windows.zip，下载好后，解压缩到D盘。配置SDK，在Windows机器上，右键单击我的电脑，选择属性－>高级，点“环境变量”按钮，修改“系统变量”下面的Path变量，把SDK tools的真实路径加入其中（即Android sdk 解压后的文件夹下的tool路径，在这里我是D:/program/android-sdk-windows/tools）。添加完后，可以在命令行下用命令测试：android --help，如果出现android的帮助命令就说明配置好了。
