cocos2dx 搭建 android 平台

Mac OS X下配置Cocos2d-x for Android(Eclipse)&IOS(Xcode)开发环境

前面一段时间只用Cocos2d-x在IOS平台下开发, 学习Cocos2d-x不就是为了他的跨平台特性么? 所以必须也要掌握在Android下的开发, 才能引爆Cocos2d-x的跨平台特性, 发挥其最大长处.

Cocos2d-x版本发展很快, 而在Android+Eclipse的开发环境配置超级复杂, 很坑爹有木有啊????

如果你发现有不一样的地方, 很有可能是版本不同造成的, 当然也可能是我搞错了, 望不吝赐教.

版本:

Cocos2d-x: cocos2d-2.0-x-2.0.3

OS X: 10.8

Xcode: 4.5.1

Eclipse: 4.2.1

NDK: android-ndk-r8b

Device: Samsung T959 cm10(Android 4.1.2)

文件路径:

Cocos2d-x: /opt/cocos2d-2.0-x-2.0.3

Android SDK:/opt/android-sdk-macosx

Android NDK:/opt/android-ndk-r8b

如果下文提及这些路径, 请替换成你自己的路径.

1.配置Cocos2d-x for Xcode.

这一块比较简单, 可以参见其他文章.

重点:install-templates-xcode.sh

2.配置普通Android开发环境

这一块包括JDK安装, Eclipse安装, ADT安装.教程也非常多.

3.Eclipse中安装CDT, 即C++开发环境

4.设置环境变量, 即编辑 ~/.bash_profile

在中添加

?

export COCOS2DX_ROOT=/opt/cocos2d-2.0-x-2.0.3

export ANDROID_SDK_ROOT=/opt/android-sdk-macosx

export ANDROID_NDK_ROOT=/opt/android-ndk-r8b

export NDK_ROOT=/opt/android-ndk-r8b

export PATH=$PATH:$ANDROID_NDK_ROOT

export PATH=$PATH:$ANDROID_SDK_ROOT

5.创建Android项目, 项目名称"CCTest".

Youngs-MacBook-Air:~ young40$ cd /opt/cocos2d-2.0-x-2.0.3/
Youngs-MacBook-Air:cocos2d-2.0-x-2.0.3 young40$ ./create-android-project.sh
use global definition of NDK_ROOT: /opt/android-ndk-r8b
use global definition of ANDROID_SDK_ROOT: /opt/android-sdk-macosx
Input package path. For example: org.cocos2dx.example
com.young40
Now cocos2d-x supports Android 2.2 or upper version

Youngs-MacBook-Air:cocos2d-2.0-x-2.0.3 young40$ 

6.编译默认的C++资源

Youngs-MacBook-Air:proj.android young40$ cd /opt/cocos2d-2.0-x-2.0.3/CCTest/proj.android/
Youngs-MacBook-Air:proj.android young40$ ./build_native.sh
NDK_ROOT = /opt/android-ndk-r8b
COCOS2DX_ROOT = /opt/cocos2d-2.0-x-2.0.3/CCTest/proj.android/../..
APP_ROOT = /opt/cocos2d-2.0-x-2.0.3/CCTest/proj.android/..
APP_ANDROID_ROOT = /opt/cocos2d-2.0-x-2.0.3/CCTest/proj.android
Using prebuilt externals
make: Entering directory `/opt/cocos2d-2.0-x-2.0.3/CCTest/proj.android'

make: Leaving directory `/opt/cocos2d-2.0-x-2.0.3/CCTest/proj.android'

7. 创建Eclipse项目, 并运行默认Demo

如图, 选择Android Project from Existing Code.

地址选择为:/opt/cocos2d-2.0-x-2.0.3/CCTest/proj.android (直接输入可能会报错, 请用鼠标选择目录)

点击下一步就将项目加入了Eclipse中.但是项目会报错.

The import org.cocos2dx.lib cannot be resolved    CCTest.java    /com.young40.CCTest/src/com/young40    line 26    Java Problem
Cocos2dxActivity cannot be resolved to a type    CCTest.java    /com.young40.CCTest/src/com/young40    line 30    Java Problem
Cocos2dxActivity cannot be resolved to a type    CCTest.java    /com.young40.CCTest/src/com/young40    line 33    Java Problem

我的解决办法是将:

/opt/cocos2d-2.0-x-2.0.3/cocos2dx/platform/android/java

作为一个项目添加进来, 即可解决报错问题.

8.编译运行

我尝试在Android2.3.3虚拟机运行项目失败.

没有关系, 我用真机测试. adb 无线连上真机(cm10真好, 自带无线调试)

Youngs-MacBook-Air:proj.android young40$ /opt/android-sdk-macosx/platform-tools/adb connect 192.168.8.139:5555
connected to 192.168.8.139:5555

OK, 运行成功, 如图.

FPS有点低哈, 我的ipad2, 都能全速60帧.

9.创建名称为CCTest的Xcode项目.

创建后你可以运行测试下.

删除项目下Classes目录

然后将目录/opt/cocos2d-2.0-x-2.0.3/CCTest/Classes添加到项目.请确保Destination是没有被选中的.这样代码将是以引用的方式存在在项目中的.

修改Classes下HelloWorldScene.cpp, 并运行测试.

CCLabelTTF* pLabel = CCLabelTTF::create("Hello Cocos2d-x!", "Thonburi", 34);

成功.cocos2d-x 2.0.3的版本在ios6上有方向旋转的问题, 应该为横屏才对.

10.在Android中重新运行.

首先运行:

/opt/cocos2d-2.0-x-2.0.3/CCTest/proj.android/build_native.sh

在Eclipse菜单中选择Project=>Clean清理下项目, 然后Run下, 可以在手机看到更改也已经生效.

11. 觉得上一步繁琐? 能不能点击Run同时也编译C++资源呢? 答案是可以的.

选中Eclipse左侧CCTest项目, 右键点击New=>Other,

在弹出对话框中选择C/C++=>Convert to a C/C++Proejct(Adds C/C++ Nature)

在接下来一屏中选择C++ Project以及 Project Type为Makefile project, Toolchains为Other

接下来Eclipse问是否切换到C++视图, 选择否. 如果不小心切换过去了, 再切换回java视图即可.

打开项目属性页面, 设置自动编译C++, 如图:

注意修改Build command为, 另外需要注意项目名称.

bash ${workspace_loc:/com.young40.CCTest}/build_native.sh NDK_DEBUG=1 V=1

点击Run,之后我这里报错, 编译提示说"please define NDK_ROOT", 需要在项目设置中添加环境变量.如图

这个时候再点击Run, 会看到Console窗口会有编译的输出, 编译成功. 运行成功.

12.消除Eclipse中的错误提示.

如果打开项目jni目录下hellocpp/main.cpp文件, 会看到大量的报错. 我们需要讲相关文件添加到项目中.

首先添加/opt/cocos2d-2.0-x-2.0.3/CCTest/Classes到项目中.如图添加一个Link类型的文件夹.

用同样方法将"/opt/cocos2d-2.0-x-2.0.3/cocos2dx"添加到项目中.

然后如图添加引用.

/opt/android-ndk-r8b/platforms/android-8/arch-arm/usr/include

/opt/cocos2d-2.0-x-2.0.3/CocosDenshion/include

这里和子龙山人翻译的老外的文章做法略有不同, 他那个方法还是要报很多错, 可能是版本不同造成的.

我这个方法也不用忽略文件, 用什么类直接鼠标点击可以看到相应声明.

这样初步的IOS&Android开发环境就集成好了.
