Mac 下配置 Android NDK 环境并搭建 Cocos2d-x 环境

首先下载和安装基本软件：

• ADT Bundle for Mac（这里面已经包含了 Android SDK、Eclipse IDE 及 ADT (Android Developer Tools)），目前版本为 v21.0.1-543035。解压为 /Users/foolbear/Documents/adt-bundle-mac-x86_64，运行 eclipse/eclipse 即可。此时 Android SDK 路径为 /Users/foolbear/Documents/adt-bundle-mac-x86_64/sdk。
• Android NDK for Mac，版本为 r8d。解压为 /Users/foolbear/Documents/android-ndk-r8d，即 Android NDK 路径。
• Cocos2d-x，这里用的是稳定的 cocos2d-2.0-x-2.0.4 版本。解压为 /Users/foolbear/Documents/cocos2d-2.0-x-2.0.4，即 Cocos2d-X 路径。

配置环境变量：
打开“终端”，输入及回应如下：

foolmbp:~ foolbear$ cd
foolmbp:~ foolbear$ pwd
/Users/foolbear
foolmbp:~ foolbear$ vi .bash_profile

编辑 .bash_profile 文件为（注意对应上面的路径）：

export ANDROID_SDK_ROOT=/Users/foolbear/Documents/adt-bundle-mac-x86_64/sdk/
export ANDROID_NDK_ROOT=/Users/foolbear/Documents/android-ndk-r8d
export COCOS2DX_ROOT=/Users/foolbear/Documents/cocos2d-2.0-x-2.0.4
export NDK_ROOT=/Users/foolbear/Documents/android-ndk-r8d
export PATH=$PATH:$ANDROID_SDK_ROOT
export PATH=$PATH:$ANDROID_NDK_ROOT

关闭当前“终端”并新开一个，下面我们要尝试编译 Cocos2dx 自带的 Sample - TestCpp：

foolmbp:~ foolbear$ cd $COCOS2DX_ROOT
foolmbp:cocos2d-2.0-x-2.0.4 foolbear$ cd samples/TestCpp/proj.android/
foolmbp:proj.android foolbear$ ./build_native.sh
NDK_ROOT = /Users/foolbear/Documents/android-ndk-r8d
COCOS2DX_ROOT = /Users/foolbear/Documents/cocos2d-2.0-x-2.0.4/samples/TestCpp/proj.android/../../..
APP_ROOT = /Users/foolbear/Documents/cocos2d-2.0-x-2.0.4/samples/TestCpp/proj.android/..
APP_ANDROID_ROOT = /Users/foolbear/Documents/cocos2d-2.0-x-2.0.4/samples/TestCpp/proj.android

make: Leaving directory `/Users/foolbear/Documents/cocos2d-2.0-x-2.0.4/samples/TestCpp/proj.android'

编译成功后，打开 Eclipse，File - Import - Android - Existing Android Code Into Workspace，选择 Root Directory 为 /Users/foolbear/Documents/cocos2d-2.0-x-2.0.4/samples/TestCpp/proj.android， Finish。这时会有三个错误，解决方法是将 /Users/foolbear/Documents/cocos2d-2.0-x-2.0.4/cocos2dx/platform/android/java 也同法 import 进来即可。

选中 TestCpp 项目，右键 - Run As - Android Application 既能在真机中运行。
