Android跑起Cocos2d-x的SimpleGame

做开发就要快速建模，而学习一个库就要快速将demo跑起来。

之前百度地图API也是一样，跑起来，看看它的运行状况是什么样的，有了感性认识之后，就更容易理解了。

Cocos2d-x是一个开源的移动游戏框架，源自cocos2d。其跨平台性导致它的包里有太多东西，而我呢，只想Android部分的。对此，我很是纠结。

因为看官网的文档，看的我是云里雾里的，总是找不到从何入手。上面描述的环境搭建复杂至极，真是令人抓狂。

今天看了一篇文章，让我硬着头皮又操练起来，终于成了。

文章名为：android基于cocos2d-x的eclipse开发环境搭建

我的开发环境在Linux下，NDK就不用那么麻烦了，Android应用开发环境也是之前就搭建好的。只等着把Cocos2d-x加进来了。

SimpleGame是其提供的一个sample，路径在cocos2d-x-2.2.1/cocos2d-x-2.2.1/samples/Cpp，下面是各个平台的式例。（题外话：之前我直接找sample，一看里面没有android目录，我就很失望的走开了。）

根据上面的文章，很快的，demo就跑起来了。

具体步骤如下：

1.将libcocos2dx导入到eclipse

        libcocos2dx是android专用的cocos2dx java库，很多有用的类都在此库中，比如例子中要用到的Cocos2dxActivity。

        路径在cocos2d-x-2.2.1/cocos2dx/platform/android/java

2.将samples/Cpp/SimpleGame/proj.android 导入到eclipse

3.复制游戏需要的资源

        cp cocos2d-x-2.2.1/samples/Cpp/SimpleGame/Resources/* cocos2d-x-2.2.1/samples/Cpp/SimpleGame/proj.android/assets/

4.复制cocos2d-x-2.2.1目录下的cocos2dx,CocosDenshion,extensions,external这4个目录到你的NDK的sources目录下,以我的电脑为例,就是/android/android-ndk-r9b/sources

5.最讨厌的，把cocos2dx/platform/third_party/android/prebuilt下的libcurl,libjpeg,libpng,libtiff,libwebp再拷到/android-ndk-r9b/sources下

5.设置NDK Location

        Eclipse中Window--->Preferences--->Android--->NDK，在NDK Location中填上或找到你ndk所在的目录，比如我的：/home/linc/dev/android/android-ndk-r9b

6.设置ndk-build的命令,为 ndk-build NDK_DEBUG=1

      点击项目SimapleGame，Alt+Enter，进入Properties for SimapleGame，点击C/C++ Build，在Build command中添加ndk-build NDK_DEBUG=1，点击Apply。

7.接上面，点开C/C++ Build，点击Tool Chain Editor，将Current builder选成Android Builder，OK。

8.项目SimapleGame右键Build Configurations--->Build all,或者单独此项目时，Project--->Build all。

在Eclipse的Console中打印出编译信息，从这些信息中我们可以看到到底有多少个文件参与了此次编译。

**** Build Finished ****

下面是我遇到的错误：

错误1.  non-numeric second argument to `wordlist' function 

此问题是NDK开发中常遇到的问题，原因是AndroidManifest.xml没有指定SDK版本。

解决办法是添加：

 <uses-sdk 
          android:minSdkVersion="9"
      android:targetSdkVersion="10"/>

错误2.创建的Android项目提示org.cocos2dx.lib.Cocos2dxActivity

可能是java那个项目没有导入进来吧，报错是找不到这个类。直接搞过来吧，将org.cocos2dx.lib包下的类全拷进来就可以了。

这是因为第一步没有做好，java库没有导入进来的缘故。
