jni cocos2d-x移植到android：helloworld

前面搭建好了android开发环境

jni开发环境，那么就来用一用目前火热的cocos2d的游戏引擎吧

所需资料：

我下载的是较老的版本 cocos2d-1.0.1-x-0.11.0。如果你和我一样，也是第一次，建议也下这个版本

ndk版本使用 r7 的。

这样之后才会遇到较少的问题

下载完，解压 cocos2d。

进入目录下修改 create-android-project.bat 这个文件

pause

修改红色字体部分为你对应的安装目录。

ok，接下来搞个helloworld吧。

哦，对了，这个需要有一个NDK_ROOT的环境变量，自己添加一下吧，不知道就百度哦。

添加完环境变量，重启计算机。

打开create-android-project.bat文件

按照提示进行输入：

第一步输入你工程包名：com.android.cocos2d.test（可以自己输入哦）

第二步输入工程名称：test

第三步窗口会列出所有可以选择的android版本，自己选择一个输入id号码，我输入 7 对应 android的2.3.3版本的

然后生成项目就ok了，可以看到当前目录下多了一个test目录，这个就是工程目录了，没看到的话刷新一下。

接下来就是编译，需要将代码编译成可以调用的so链接库

打开cygwin

进入生成的项目的android目录

执行build_native.sh这个shell脚本。就开始编译了。需要一点时间

如果你使用的不是我所说的对应的版本，那么可能这里会遇到形形易做图的问题，也欢迎把问题贴给我，我可能可以替你解决。但还是建议百度，这样速度来的比较块一点。
