Facebook BUCK编译APK包

ANT是google编译apk包的工具，但是发现编译效率不是那么高。编译是开启四进程的。
发现Facebook的BUCK开源工具，就尝试这使用，结果发现效果很不错

参考文档

http://facebook.github.io/buck/setup/quick_start.html

http://buck.readthedocs.org/en/latest/index.html

安装很简单，按照上面的文档

git clone git@github.com:facebook/buck.git
cd buck
ant
设置环境变量

我的其中一个BUCK文件

#打包Android资源文件,一般生成R.java文件
android_resource(
  name = 'res',
  res = 'res',
  assets = 'assets',
  deps = [
     '//depend_project_1/workspace:ITelephony',  #依赖工程
   ],
  package = 'com.XX.android.XX',   #资源包名称
)

#输出目标是一个包含了以及编译的class文件和资源文件的jar包
android_library(
  name = 'mainsrc',
  srcs = glob(['src/**/*.java']),
  visibility = [ 'PUBLIC' ],
  deps = [
    ':res',
    ':support',
    ':zxing-core',
    ':aidl',
    ':IPackageStatsObserver',
    ':IInAppBillingService',
    ':AnyShare',
    ':universal',
    ':GetJarSDK',
    ':FlurryAgent',
    '//depend_project_1/workspace:google',
    '//depend_project_1/workspace:ITelephony',

  ]
)

#生成一个Android APK
android_binary(
   name = 'main',
   manifest = 'AndroidManifest.xml',
   target = 'Google Inc.:Google APIs:19',
   keystore = ':debug_keystore',
   package_type = 'release',
   proguard_config = 'proguard.cfg',  #混淆
   deps = [
     ':mainsrc',
   ],
)

#apk包签名
keystore(
  name = 'debug_keystore',
  store = 'debug.keystore',
  properties = 'debug.keystore.properties',
)

#aidl文件编译成java
gen_aidl(
    name = 'aidl',
    aidl = 'src/android/content/pm/IPackageDataObserver.aidl',
    import_path = 'main_project/workspace/src',
    visibility = [ 'PUBLIC' ],
)

gen_aidl(
    name = 'PackageStats',
    aidl = 'src/android/content/pm/PackageStats.aidl',
    import_path = 'main_project/workspace/src/android/content/pm/',
    visibility = [ 'PUBLIC' ],
 )

gen_aidl(
    name = 'IPackageStatsObserver',
    aidl = 'src/android/content/pm/IPackageStatsObserver.aidl',
    import_path = 'main_project/workspace/src/',
    visibility = [ 'PUBLIC' ],
)

gen_aidl(
   name = 'IInAppBillingService',
   aidl = 'src/com/android/vending/billing/IInAppBillingService.aidl',
   import_path = 'main_project/workspace/src/',
   visibility = [ 'PUBLIC' ],
)

#用来指向一个第三方的jar文件（比如junit.jar）并且用作java_library()规则的依赖

prebuilt_jar(
  name = 'support',
  binary_jar = 'libs/android-support-v4.jar',
)
prebuilt_jar(
  name = 'libammsdk',
  binary_jar = 'libs/libammsdk.jar',
)

prebuilt_jar(
   name = 'weibo',
   binary_jar = 'libs/weibo.sdk.android.sso.jar',
)

prebuilt_jar(
   name = 'AnyShare',
   binary_jar = 'libs/AnyShare-FullSDK.jar',
)

prebuilt_jar(
   name = 'universal',
   binary_jar = 'libs/universal-image-loader-1.8.4-with-sources.jar',
)   

prebuilt_jar(
   name = 'GetJarSDK',
   binary_jar = 'libs/GetJarSDK-3.4.4.20130503.06.jar',
) 

prebuilt_jar(
   name = 'FlurryAgent',
   binary_jar = 'libs/FlurryAgent.jar',
)
prebuilt_jar(
   name = 'zxing-core',
   binary_jar = 'libs/zxing-core.jar',
)

#生成定义路径，生成apk名字是main.apk
project_config(
   src_target = ':main',
)

错误：

error: constant expression required
case R.styleable.AdvancedImageView_radius:

这个是因为代码里面使用switch case
将他改成if else形式
原因：http://tools.android.com/tips/non-constant-fields
其他错误解决没有记录。。

速度比较

  ant 构建(四进程): 215 个渠道包，用时 3 小时 02 分,因为是四个进程,每个包构建的时间平均是 200 秒


buck 构建(四进程): 相同代码,相同渠道，用时 50 分,平均一个包用时 56 秒
