[原]Android打包之跨平台打包

Android自动打包流程详细图：

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
import re
import sys
import time
import shutil
import hashlib

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]*)"

# delete file folder
def delete_file_folder(src):
    if os.path.isfile(src):
        try:
            os.remove(src)
        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

# calc file md5
def calcMD5(filepath):
    with open(filepath,'rb') as f:
        md5obj = hashlib.md5()
        md5obj.update(f.read())
        hash = md5obj.hexdigest()
        return hash

# get source code from svn Repository
def get_source_code():
    if (os.path.exists(release_apk_path)):
        print release_apk_path + ' exists!'
    else:
        os.makedirs(release_apk_path)       

    if (os.path.exists(source_dir)):
        os.chdir(source_dir)
        os.system('svn update')
    else:
        os.makedirs(source_dir)
        os.chdir(source_dir)
        os.system('svn checkout https://github.com/clarck/AutoBuildProject/trunk .')

# clear classes file folder
def clear_classes_folder():
    classes_abs_path = source_dir + '/' + build_bin_classes_path
    if (os.path.exists(classes_abs_path)):
        delete_file_folder(classes_abs_path)
    else:
        os.makedirs(classes_abs_path) 

# get svn revision
def get_revision():
    rev = os.popen(rev_cmd).read()
    m = re.search(rev_pattern, rev)
    if m == None:
        return None
    return m.group(1)

# get current time
def get_time():
    return time.strftime('%Y-%m-%d_%H-%M-%S', time.localtime(time.time()))

# ant build
def ant_build():
    os.system('android update project -p . --target android-19')
    os.system('ant clean & ant release')

# copy apk file to target folder
def copy_apk():
    apk_file = source_dir + '/' + build_bin_path + '/' + build_apk_name
    target_apk_file = release_apk_path + '/' + build_apk_name
    if (os.path.exists(apk_file)):
        shutil.copyfile(apk_file, target_apk_file)
    else:
        print apk_file + ' is not exists!'

# delete source code files
def delete_source_file():
    delete_file_folder(source_dir)

# publish apk
def publish(date, rev):
    if (os.path.exists(publish_apks)):
        print publish_apks + ' exists!'
    else:
        os.makedirs(publish_apks)

    md5 = calcMD5(release_apk_path + '/' + build_apk_name)
    apk_file = release_apk_path + '/' + build_apk_name
    publish_file = publish_apks + '/' + date + '_' + rev + '_' + 'release.apk'
    shutil.move(apk_file, publish_file)
    delete_file_folder(release_apk_path)

# main function
def main():
    get_source_code()
    clear_classes_folder()
    rev = get_revision()
    date = get_time()
    ant_build()
    copy_apk()
    publish(date, rev)    

if __name__ == '__main__':
    main()

最后执行:python build.py即可。
