Android cocos2dx游戏开发——cocos2dx-2.2.3 环境配置

      cocos2dx-2.2.3下载地址：http://www.cocos2d-x.org/download

      cocos引擎之前的版本要再在create-android-project.bat文件中设置环境变量，2.2.3之后的版本中已经找不到该文件了。

一、导入示例工程

      我们先导入一个cocos提供的示例工程samples\Cpp\HelloCpp：

二、导入库工程

      我们导入例子工程后发现找不到类Cocos2dxActivity，因为示例工程引用了一个库工程，所以我们要导入该工程，该工程在cocos2dx\platform\android\java下：

 

 

三、将cygwin/bin添加到环境变量path中

      我们导入了库工程，但是发现还是有错误，我们运行一下工程，看看console的输出：

       从输出中我们可以看到在PATH中找不到bash，bash就是cygwin/bin目录下，把该路径添加到path中，配置之后要重启一下Eclipse。

四、添加NDK_ROOT变量

      我们添加完bash到path后再运行程序，发现编译还是报错：  

      这次是因为缺少NDK_ROOT，可以再环境变量中添加，也可以在Eclipse->Window->Preference->C/C++->Build->Enviroment中添加：

 

五、运行

      经过以上几步，我们再运行程序就可以成功编译了。

 

六、问题补充：

      1、运行时报"Unable to add 'C:\app\Android\ndk\cocos2d-x-2.2.3\samples\Cpp\HelloCpp\proj.android\assets\fonts\Marker Felt.ttf': Zip add failed"的错误

      解决方法：打开cygwin安装目录下的etc\fstab文件，在文件最后添加

none /cygdrive cygdrive binary,noacl,posix=0,user 0 0

     

      2、用genymotion运行例子时遇到"INSTALL_FAILED_CPU_ABI_INCOMPATIBLE"的错误

      解决方法：http://blog.csdn.net/cjj7905150/article/details/18270103

      3、cocos官方提供了的环境配置指导，在例子工程中有个README.md文件，有更加详细的安装指导

## Prerequisites:

* Android NDK
* Android SDK **OR** Eclipse ADT Bundle
* Android AVD target installed

## Building project

There are two ways of building Android projects.

1. Eclipse
2. Command Line

### Import Project in Eclipse

#### Features:

1. Complete workflow from Eclipse, including:
	* Build C++.
	* Clean C++.
	* Build and Run whole project.
	* Logcat view.
	* Debug Java code.
	* Javascript editor.
	* Project management.
2. True C++ editing, including:
	* Code completion. 
	* Jump to definition.
	* Refactoring tools etc. 
	* Quick open C++ files.


#### Setup Eclipse Environment (only once)


**NOTE:** This step needs to be done only once to setup the Eclipse environment for cocos2d-x projects. Skip this section if you've done this before.

1. Download Eclipse ADT bundle from [Google ADT homepage](http://developer.android.com/sdk/index.html)

   **OR**

   Install Eclipse with Java. Add ADT and CDT plugins.

2. Only for Windows
    1. Install [Cygwin](http://www.cygwin.com/) with make (select make package from the list during the install).
    2. Add `Cygwin\bin` directory to system PATH variable.
    3. Add this line `none /cygdrive cygdrive binary,noacl,posix=0,user 0 0` to `Cygwin\etc\fstab` file.
   
3. Set up Variables: 
	1. Path Variable `COCOS2DX`: 
		* Eclipse->Preferences->General->Workspace->**Linked Resources**
		* Click **New** button to add a Path Variable `COCOS2DX` pointing to the root cocos2d-x directory.
		![Example](https://lh5.googleusercontent.com/-oPpk9kg3e5w/UUOYlq8n7aI/AAAAAAAAsdQ/zLA4eghBH9U/s400/cocos2d-x-eclipse-vars.png)

	2. C/C++ Environment Variable `NDK_ROOT`: 
		* Eclipse->Preferences->C/C++->Build->**Environment**.
		* Click **Add** button and add a new variable `NDK_ROOT` pointing to the root NDK directory.
		![Example](https://lh3.googleusercontent.com/-AVcY8IAT0_g/UUOYltoRobI/AAAAAAAAsdM/22D2J9u3sig/s400/cocos2d-x-eclipse-ndk.png)
		* Only for Windows: Add new variables **CYGWIN** with value `nodosfilewarning` and **SHELLOPTS** with value `igncr`
		
4. Import libcocos2dx library project:
	1. File->New->Project->Android Project From Existing Code.
	2. Click **Browse** button and open `cocos2d-x/cocos2dx/platform/android/java` directory.
	3. Click **Finish** to add project.
	
#### Adding and running from Eclipse

![Example](https://lh3.googleusercontent.com/-SLBOu6e3QbE/UUOcOXYaGqI/AAAAAAAAsdo/tYBY2SylOSM/s288/cocos2d-x-eclipse-project-from-code.png) ![Import](https://lh5.googleusercontent.com/-XzC9Pn65USc/UUOcOTAwizI/AAAAAAAAsdk/4b6YM-oim9Y/s400/cocos2d-x-eclipse-import-project.png)

1. File->New->Project->Android Project From Existing Code
2. **Browse** to your project directory. eg: `cocos2d-x/cocos2dx/samples/Cpp/TestCpp/proj.android/`
3. Add the project 
4. Click **Run** or **Debug** to compile C++ followed by Java and to run on connected device or emulator.


### Running project from Command Line

    $ cd cocos2d-x/samples/Cpp/TestCpp/proj.android/
    $ export NDK_ROOT=/path/to/ndk
    $ ./build_native.sh
    $ ant debug install

If the last command results in sdk.dir missing error then do: 

    $ android list target
    $ android update project -p . -t (id from step 6)
    $ android update project -p cocos2d-x/cocos2dx/platform/android/java/ -t (id from step 6)
