本文记载的是一个HELLO WORLD级别的入门程序在如题所示环境下的编译构建过程。
说明：如今安装Android Studio 1.4，它会自动安装Gradle 2.4（早期却不是这样），但遗憾的是没有下载对应的.zip文件。所以，后面在命令行编译时还需要再次下载这个文件。
另外，在MAC环境下下载安装Cocos2d-x 3.9和Android Studio 1.4的步骤，在此省略描述。
环境变量配置
终端工具下，运行如下命令：
vim ~/.bash_profile
输入如下内容：
ANT_ROOT='/usr/local/Cellar/ant/1.9.6/bin'
exportANT_ROOT
COCOS_PATH='~/Downloads/cocos2d-x-3.9/tools/cocos2d-console/bin'
exportCOCOS_PATH
exportPATH=$PATH:$COCOS_PATH:$ANT_ROOT
exportPATH=$PATH:/Users/zxzpc/Library/Android/sdk/tools
exportPATH=$PATH:/Users/zxzpc/LIbrary/Android/sdk/build-tools
exportPATH=$PATH:/Users/zxzpc/Downloads/android-ndk-r10e
exportPATH=$PATH:/Users/zxzpc/usr/local/Cellar/ant/1.9.6/bin
exportANDROID_SDK_ROOT=/Users/zxzpc/Library/Android/sdk
exportANDROID_NDK_ROOT=/Users/zxzpc/Downloads/android-ndk-r10e
exportNDK_ROOT=/Users/zxzpc/Downloads/android-ndk-r10e
#Add gradle variable export
GRADLE_HOME='/Applications/Android\Studio.app/Contents/gradle/gradle-2.4/bin'
exportPATH=$PATH:$GRADLE_HOME
接下来运行下面命令：
source ~/.bash_profile
注意，这里的source命令用于重新执行刚刚修改的系统环境配置文件，使之内容立即生效，而不必注销并重新登录。这一点很重要；这样以后，从命令行下执行cocos命令，它就能够自动找到上述SDK所在位置。
Android Studio 1.4下打开工程与修改文件gradle-wrapper.properties
启动Android Studio 1.4打开示例工程MyHelloWorld（使用命令“File”－“Open”打开文件夹proj.android-studio即可）。因为文件gradle-wrapper.properties在后期命令行编译时使用到，所以需要根据实际情况进行修改。初始内容如下：
#Fri Jul 31 20:40:49 CST 2015
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-2.4-all.zip
但是，我在第一次命令行编译时出现网络连接错误。大致的意思是，连接不到上面一行指定的网址，这种原因估计一般程序员都知道。于是，根据网络上的提示，我想也把文件gradle-2.4-all.zip下载到本地，并修改上面的distributionUrl参数。
文件gradle-2.4-all.zip下载倒不是难事，大家可以参考本文后面的下载网址。但是，修改文件倒是出现麻烦了。修改后内容如下：
#Fri Jul 31 20:40:49 CST 2015
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
#distributionUrl=https\://services.gradle.org/distributions/gradle-2.4-all.zip
distributionUrl==file\:/Users/zxzpc/Downloads/gradle-2.4-all.zip
但是，接下来，再次在命令行运行命令cocos compile -p android --android-studio时，还是出现错误，如下所示：

问题显然出在『Illegal character in schemename at index 0』这一句。
就是这个问题上，我纠结了不少时间，尽管这种错误提示看起来并不复杂。因为实在没有多少这方面的经验，所以问题停留在：在.zip文件内容出现问题，还是上面引用本机文件格式出现问题？
再次修改文件与命令行下成功编译
经过不断尝试与借鉴网络查询结果，最终我还是把上面文件内容还原到最初状态，如下所示：
#Fri Jul 31 20:40:49 CST 2015
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

再次启动MAC终端，CD到示例工程HELLOWORLD目录下，然后执行如下命令：
cocos compile -p android --android-studio
显示及输出内容如下：

显然，下载gradle-2.4-all.zip和相应解压花费了不少时间，但总算有了一个初步的惊喜。而且，如读者所想，使用本地的文件是节约时间的最佳办法。无奈，拙人我现在还没有找到。以后找到，一定记录下来。
剩下的好办了，把生成的APK文件设法复制到我的三星I9100机器上（还是Ａndroid 2.3.4版本）。安装运行即可，截图如下：
注意：图中中文显示不正常，是因为我没有作相应处理而已。
小结
Android Studio 1.4编译与构建速度比Eclipse快几十倍，模拟器启动速度也快得多。尽管我的编译工程不是在IDE环境下实现的。
命令行编译还是更迅速，值得推荐。
本次记录的是MAC环境命令行下的编译生成APK文件的过程。走了不少曲折的路，记录下来供自己备忘，也供同志们参考。
