批量提取出apk中所需的文件

应用场景

我需要批量提取出apk中的classes.dex文件，如何在不解压的情况下快速提取出dex文件？在这里使用python自带的zipfile类，可以轻松的解决这个问题。

代码实现

#!/usr/bin/env python# coding=utf-8import osimport zipfilepath="D:/tao/test/apkstore" # this is apk files' store pathdex_path="D:/tao/test/dex/" # a directory  store dex filesapklist = os.listdir(path) # get all the names of appsif not os.path.exists(dex_path):    os.makedirs(dex_path)for APK in apklist:    portion = os.path.splitext(APK)    if portion[1] == ".apk":        newname = portion[0] + ".zip" # change them into zip file to extract dex files        #print newname        os.chdir(path)        os.rename(APK,newname)        apkname = portion[0]        #zip_apk_path = os.path.join(path,APK) # get the zip files        zip_apk_path = path+"/"+newname        z = zipfile.ZipFile(zip_apk_path, 'r') # read zip files        for filename in z.namelist():            #print filename            if filename.endswith(".dex"):                dexfilename = apkname + ".dex"                dexfilepath = os.path.join(dex_path, dexfilename)                f = open(dexfilepath, 'w+') # eq: cp classes.dex dexfilepath                f.write(z.read(filename))print "all work done!"

借鉴了一下两篇文章的解决思路，达到了我想要的效果。
