首先下载eclipse和cdt，我的版本号依次是:Version: Indigo Service Release 2和Version: 1.0.0.201202111925，再下载windows的ndk，我使用的是android-ndk-r9d

什么cygwin这等东西，太恶心了，下载慢，大的要命！复杂，今天给一个最爽的编译教程。

前面的cdt插件怎么这里pass，网上教程很多的。直接配置。。。

启动eclipse，然后点Windows-Prefrences-C/C++-Build-Envionment，添加以下路径

然后创建一个android工程，把代码全部删除，资源全部删除，AndroidManifest.xml内容如下
