怎么将cocos2d-js 3.x 成功在android平台编译打包 测试ok

转载：http://www.cocoachina.com/bbs/read.PHP?tid=209353

1. 环境配置

使用的操作系统是64位的Ubuntu Server 14.04，首先下载cocos2d-js开发包和android必须的NDK、SDK等开发库，有更新的版本请下载新版本，全部解压到/home/magic（本文测试用户目录）下的目录。

cocos2d-js-v3.0-beta.zip
android-ndk-r9d-linux-x86_64.tar.bz2
android-sdk_r22.6.2-linux.tgz
apache-ant-1.9.4-bin.tar.bz2
配置cocos2d-js：
magic@magic:~$ cd cocos2d-js-v3.0-beta
magic@magic:~/cocos2d-js-v3.0-beta$ ./setup.py
Setting up cocos2d-x...
->Check environment variable COCOS_CONSOLE_ROOT
->Find environment variable COCOS_CONSOLE_ROOT...
->COCOS_CONSOLE_ROOT is found : /home/magic/cocos2d-js-v3.0-beta/tools/cocos2d-console/bin
->Configuration for Android platform only,you can also skip and manually edit "/home/magic/.bashrc"
->Check environment variable NDK_ROOT
->Find environment variable NDK_ROOT...
->NDK_ROOT is found : /home/magic/android-ndk-r9d
->Check environment variable ANDROID_SDK_ROOT
->Find environment variable ANDROID_SDK_ROOT...
->ANDROID_SDK_ROOT is found : /home/magic/android-sdk-linux
->Check environment variable ANT_ROOT
->Find environment variable ANT_ROOT...
->ANT_ROOT is found : /home/magic/apache-ant-1.9.4/bin/
Please execute command: "source /home/magic/.bashrc" to make added system variables take effect
magic@magic:~/cocos2d-js-v3.0-beta$ source /home/magic/.bashrc
安装java的运行和开发环境：
magic@magic:~$ sudo apt-get install default-jre
magic@magic:~$ sudo apt-get install default-jdk
进入android sdk的目录下载更新android平台和第三方库文件：
magic@magic:~$ cd android-sdk-linux
magic@magic:~/android-sdk-linux$ tools/android update sdk --no-ui
如果不更新，那么用cocos没法编译。这个更新下载时间非常长，会把所有android版本的sdk文件都下载下来，建议下班前执行，第二天上班再来看。
如果你的操作系统是64位的，那么还需要安装32位的编译器：
magic@magic:~$ sudo apt-get install libstdc++6:i386 libgcc1:i386 zlib1g:i386 libncurses5:i386 --no-install-recommends
否则后面cocos编译的时候会出现类似如下错误：
BUILD Failed
/home/magic/android-sdk-linux/tools/ant/build.xml:601: The following error occurred while executing this line:
/home/magic/android-sdk-linux/tools/ant/build.xml:653: The following error occurred while executing this line:
/home/magic/android-sdk-linux/tools/ant/build.xml:698: Execute Failed: java.io.IOException: Cannot run program "/home/magic/android-sdk-linux/build-tools/19.1.0/aapt" (in directory "/home/magic/project/MyGame/frameworks/js-bindings/cocos2d-x/cocos/platform/android/java"): error=2,No such file or directory
因为aapt是个32的程序，它要调用32位编译器。
2. 编译测试
生成一个测试项目：
magic@magic:~$ cocos new MyGame -l js -d /home/magic/project/
修改frameworks/runtime-src/proj.android/AndroidManifest.xml可以设置游戏启动是横屏还是竖屏，默认是landscape：
android:screenorientation="portrait"
编译这个测试项目：
magic@magic:~$ cd project/MyGame/
magic@magic:~/project/MyGame$ cocos compile -p android
...
BUILD SUCCESSFUL
Total time: 12 seconds
Move apk to /home/magic/project/MyGame/runtime/android
build succeeded.
magic@magic:~/project/MyGame$ ls -l /home/magic/project/MyGame/runtime/android
total 6120
-rw-rw-r-- 1 magic magic 6263119 Jun 16 16:08 MyGame-debug.apk

这样编译的是debug版本，方便测试调试。一般开发阶段这样已经就可以了。

注意： 如果cocos compile -p android 出现如下问题：

如题，cocos2dx3.13.1项目编译android时报错：

Android NDK: WARNING: APP_PLATFORM android-19 is larger than android:minSdkVersion 9 in ./AndroidManifest.xml
Android NDK: ERROR:/Users/Evan/Documents/android-ndk/sources/cxx-stl/gnu-libstdc++/Android.mk:gnustl_static: LOCAL_SRC_FILES points to a missing file
Android NDK: Check that /Users/Evan/Documents/android-ndk/sources/cxx-stl/gnu-libstdc++/4.9/libs/armeabi/libgnustl_static.a exists or that its path is correct
make: Entering directory `/Users/Evan/Documents/work-fight/Jdysrfight/fightGame/frameworks/runtime-src/proj.android'
/Users/Evan/Documents/android-ndk/build/core/prebuilt-library.mk:45: *** Android NDK: Aborting . Stop.
make: Leaving directory `/Users/Evan/Documents/work-fight/Jdysrfight/fightGame/frameworks/runtime-src/proj.android'

解决方法：我之前用的ndk版本为r9，换成r10c就好了。

备注：/Users/Evan/Documents/android-ndk/sources/cxx-stl/gnu-libstdc++/4.9/libs/armeabi/libgnustl_static.a exists or that its path is correct

注意这里有个4.9/,r9d里只有4.6,4.8没有4.9的，所以暂时是换了ndk版本解决的。

3. 发布release版本
如果要编译release版本，那么首先要创建keystore：
magic@magic:~/project/MyGame$ keytool -genkey -alias demo.keystore -keyalg RSA -validity 3650 -keystore demo.keystore
说明：
genkey 产生密钥
-alias demo.keystore 别名 demo.keystore
-keyalg RSA 使用RSA算法对签名加密
-validity 3650 有效期限10年
-keystore demo.keystore
会要求输入keystore的密码，以及组织名字等相关信息，填好后在当前目录生成keystore文件：
magic@magic:~/project/MyGame$ ls -l demo.keystore
-rw-rw-r-- 1 magic magic 2195 Jun 17 09:04 demo.keystore
然后用如下命令编译发布：
magic@magic:~/project/MyGame$ cocos compile -p android -m release
编译完后，会提示你输入keystore文件：
Move apk to /home/magic/project/MyGame/publish/android
Please input the absolute/relative path of ".keystore" file:
输入刚才生成的demo.keystore完整路径，比如这里是/home/magic/project/MyGame/demo.keystore，然后会提示输入这个keystore的密码，alias以及alias的密码，然后脚本会自动做签名，生成做了签名的apk文件：
magic@magic:~/project/MyGame$ ls -l /home/magic/project/MyGame/publish/android/MyGame-release-signed.apk
-rw-rw-r-- 1 magic magic 6145648 Jun 17 09:07 /home/magic/project/MyGame/publish/android/MyGame-release-signed.apk
