在前面一些博客我们知道了如何通过命令行打包，如何通过Eclipse打包，如何通过编写shell脚本来进行打包，但是这些都不能很好的跨平台进行打包。

因Python本身具有很好的跨平台特性，故本博就是通过使用Python来进行编写跨平台打包脚本，脚本如下(build.py)：

#!/bin/python
# build Android application package (.apk) from the command line using the SDK tools

import os

build_root = os.path.dirname(os.path.abspath(‘__file__‘))
build_source_name = ‘source‘
build_apk_name = ‘FullscreenActivity-release.apk‘
release_apk_path = build_root + ‘/release_apks‘
publish_apks = build_root + ‘/publish_apks‘
android_sdk = os.environ.get(‘ANDROID_SDK‘)
build_tool_ant_path = android_sdk + ‘/tools/ant‘
build_bin_path = ‘bin‘
build_bin_classes_path = ‘classes‘
source_dir = build_root + ‘/‘ + build_source_name    

rev_cmd = "svn info"
rev_pattern = r"Last Changed Rev: ([0-9]*)"

        try:

        except:
            pass
    elif os.path.isdir(src):
        for item in os.listdir(src):
            itemsrc = os.path.join(src,item)
            delete_file_folder(itemsrc) 
        try:
            os.rmdir(src)
        except:
            pass
