首先下载eclipse和cdt。我的版本依次是: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。网上教程非常多的。直接配置。

。。

启动eclipse，然后点Windows-Prefrences-C/C++-Build-Envionment。加入下面路径

然后创建一个androidproject，把代码所有删除。资源所有删除，AndroidManifest.xml内容例如以下

<?xml version="1.0" encoding="utf-8"?>

路径必须是刚才创建project的jni文件夹。名字随便，重点看图

好了点完毕，然后打开main.cpp发现N多错误，直接下设置一下环境变量。右键project，属性（是刚创建的C++project）

接下来看图，把全部的库加进去。

最后加一个Symbol，事实上就是定义一个宏，告诉编译器我如今的平台是Android。add

最后点OK，全部的函数都能正常识别。提示功能也能够用了。开发效率高多了。

编译直接点锤子即可了。

然后在原来的project执行安装即可了！
