win7 64位下安装cocos2d-x 2.2 for android

Android开发者做cocos2dx最大的绊脚石，不是c++，而是环境的搭建——摘自某博客

这几天在家装cocos2dx，2.2版本，（3.0 alpha版还没有试成功，改天吧），各种报错再加上下载速度不给力，断断续续的装了好几天，终于看到了它们的logo（据说是个奔跑的椰子）。把我个人的经验记下，能够以后提醒自己，帮助别人。

安装环境：

win7 64位

安装项：

cocos2d-x 2.2.1 http://www.cocos2d-x.org/download

android ADT bundle for Windows http://developer.android.com/sdk/index.html (包含Eclipse，ADT plugin和android SDK)

android NDK r9c http://developer.android.com/tools/sdk/ndk/index.html
cygwin 1.7.27 http://cygwin.com/setup-x86_64.exe

安装方法参照 cocos2d-x-2.2.1\samples\Cpp\HelloCpp\proj.android 目录下的README。

#### 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.


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.


* Only for Windows: Add new variables **CYGWIN** with value `nodosfilewarning` and **SHELLOPTS** with value `igncr`

注：如果在cygwin里用命令行build_native.sh编译，要在windows环境变量里加上这几项，否则还是会报如下错误

Please define NDK_ROOT in your environment or in local.properties

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

 

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.

常见错误：

1. java.lang.UnsatisfiedLinkError: Couldn't load xxx: findLibrary returned null

与模拟器的CPU选择有关，一般是因为选择了x86的架构，在AVD manager里把CPU改成ARM架构即可。NDK在r6之后支持x86架构了，但需要在项目里添加一个参数。

Support x86 and armxxx

Change the APP_ABI in HelloWorld/android/jni/Application.mk

APP_ABI := armeabi armeabi-v7a x86

详见http://www.cocos2d-x.org/wiki/Build_HelloWorld_on_android_x86_platform
据我观察，这样做会在项目得libs生成一个x86文件夹，并生成.so文件

2. 运行错误：java.lang.IllegalArgumentException: No configs match configSpec

我所找到的解决方法是将AVD的target调至4.0以上，不包括4.0

3. Errors running builder 'Integrated External Tool Builder' on project 'patrol'

解决方法是：

右键项目选择“Properties”，再选择“Builders”，删除丢失的builder。

4. Unable to find native library

起初我用java build path选择libcocos2dx当作reference project，后来发现还是不行。最终的解决方式就是把cocos2dx生成的libcocos2dx.jar拷贝入项目的libs目录下即可。
