在不同操作系统下编译Android源码需要更改一些Android源码的配置项，脚本用于自动化更改配置项.zip

# coding=gbk # Android4.X在OS X10.10.X上编译时，由于Android源码的配置原因无法直接正确的编译， # 需要修改一些配置才能正确的编译，这个脚本就是用于自动化修改Android源码的配置，修改完成后 # 可以使Android4.X在OS X10.10.X上正确编译。 # 需要说明的是：Android4.X编译所使用的jdk必须是jdk6，所以如果你的电脑上没有jdk6，那么请下载。 ''' 脚本参数说明： -d：可选参数，指定Android源码根目录。如果本脚本在Android源码根目录，那么可以不输入这个参数，否则必须输入这个参数。 -j：可选参数，jdk6的java home路径。如果你的电脑上的jdk环境变量是jdk6，那么可以不输入这个选项， 否则要么输入这个参数，要么你自己设置jdk6的环境变量。注意：本脚本设置的环境变量只在当前终端上下文中有效。 ''' __author__ = 'buwai' import os import sys import getopt import commands import shutil import logging import re class MacAndroidBuildEnv: __androidRoot = None __javaHome = None __hostMakeFilePath = None __macSdkVersion = None __jniGeneratorPath = None def setAndroidRoot(self, androidRoot): self.__androidRoot = androidRoot self.__hostMakeFilePath = self.__androidRoot + r"/build/core/combo/HOST_darwin-x86.mk" # 如果原件存在，则将原件拷贝名为HOST_darwin-x86.mk的文件 origHostMakeFilePath = self.__hostMakeFilePath + ".orig" if (os.path.isfile(origHostMakeFilePath)): shutil.copy(origHostMakeFilePath, self.__hostMakeFilePath) # 获得当前Android源码支持的mac sdk版本 macSdkVersionSupported = self.__getMacSdkVersionSupported(buildEnv.getHostMakeFilePath()) #print("macSdkVersionSupported: %s" % macSdkVersionSupported) # get mac sdk version status, macSdkVersionsInstalled = commands.getstatusoutput(r'xcodebuild -showsdks | grep macosx | sort | sed -e "s/.*macosx//g"') macSdkVersionsInstalled = macSdkVersionsInstalled.splitlines();
