本文記載的是一個HELLO WORLD級別的入門程序在如題所示環境下的編譯構建過程。
說明：如今安裝Android Studio 1.4，它會自動安裝Gradle 2.4（早期卻不是這樣），但遺憾的是沒有下載對應的.zip文件。所以，后面在命令行編譯時還需要再次下載這個文件。
另外，在MAC環境下下載安裝Cocos2d-x 3.9和Android Studio 1.4的步驟，在此省略描述。
終端工具下，運行如下命令：
vim ~/.bash_profile
輸入如下內容：
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
接下來運行下面命令：
source ~/.bash_profile
注意，這里的source命令用于重新執行剛剛修改的系統環境配置文件，使之內容立即生效，而不必注銷并重新登錄。這一點很重要；這樣以后，從命令行下執行cocos命令，它就能夠自動找到上述SDK所在位置。
啟動Android Studio 1.4打開示例工程MyHelloWorld（使用命令“File”－“Open”打開文件夾proj.android-studio即可）。因為文件gradle-wrapper.properties在后期命令行編譯時使用到，所以需要根據實際情況進行修改。初始內容如下：
#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，我在第一次命令行編譯時出現網絡連接錯誤。大致的意思是，連接不到上面一行指定的網址，這種原因估計一般程序員都知道。于是，根據網絡上的提示，我想也把文件gradle-2.4-all.zip下載到本地，并修改上面的distributionUrl參數。
文件gradle-2.4-all.zip下載倒不是難事，大家可以參考本文后面的下載網址。但是，修改文件倒是出現麻煩了。修改后內容如下：
#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，接下來，再次在命令行運行命令cocos compile -p android --android-studio時，還是出現錯誤，如下所示：

問題顯然出在『Illegal character in schemename at index 0』這一句。
就是這個問題上，我糾結了不少時間，盡管這種錯誤提示看起來并不復雜。因為實在沒有多少這方面的經驗，所以問題停留在：在.zip文件內容出現問題，還是上面引用本機文件格式出現問題？
經過不斷嘗試與借鑒網絡查詢結果，最終我還是把上面文件內容還原到最初狀態，如下所示：
#Fri Jul 31 20:40:49 CST 2015
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME

再次啟動MAC終端，CD到示例工程HELLOWORLD目錄下，然后執行如下命令：
cocos compile -p android --android-studio
顯示及輸出內容如下：

顯然，下載gradle-2.4-all.zip和相應解壓花費了不少時間，但總算有了一個初步的驚喜。而且，如讀者所想，使用本地的文件是節約時間的最佳辦法。無奈，拙人我現在還沒有找到。以后找到，一定記錄下來。
剩下的好辦了，把生成的APK文件設法復制到我的三星I9100機器上（還是Ａndroid 2.3.4版本）。安裝運行即可，截圖如下：
注意：圖中中文顯示不正常，是因為我沒有作相應處理而已。
Android Studio 1.4編譯與構建速度比Eclipse快幾十倍，模擬器啟動速度也快得多。盡管我的編譯工程不是在IDE環境下實現的。
命令行編譯還是更迅速，值得推薦。
本次記錄的是MAC環境命令行下的編譯生成APK文件的過程。走了不少曲折的路，記錄下來供自己備忘，也供同志們參考。
Gradle下載頁面：http://services.gradle.org/distributions。非常全面，值得推薦。
