如果需要批量分析apk以及每个apk文件中的classes.dex 文件。怎么提取出它们?将apk改后缀名变为.zip文件,之后在解压,提取出每个apk文件中的classes.dex文件,这是一个可行的方案。但是中间解压大量的apk文件会占据我们的大量磁盘存储空间,怎么在不解压文件的情况下提取出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。
#!/usr/bin/env python # coding=utf-8 ''' @author : Chicho @version : 1.0 @ date : Jan 4, 2015 01:54 @function : extract dexs file from apk files * create a new directory to store all dex files @running : python dex_extract.py ''' import os import zipfile path="/home/chicho/test/test/" # this is apk files' store path dex_path="/home/chicho/test/test/dex/" # a directory store dex files apklist = os.listdir(path) # get all the names of apps if 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 os.rename(APK,newname) if APK.endswith(".zip"): apkname = portion[0] zip_apk_path = os.path.join(path,APK) # get the zip files z = zipfile.ZipFile(zip_apk_path, 'r') # read zip files for filename in z.namelist(): 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!"
利用这个方法还可以从apk文件中批量的提取出其他文件。比如说so文件等。
