最近Debian有Python包androguard:

Description-en: full Python tool to play with Android files
 Androguard is a full Python tool to play with Android files.
  * DEX, ODEX
  * APK
  * Android's binary xml
  * Android resources
  * Disassemble DEX/ODEX bytecodes
  * Decompiler for DEX/ODEX files

安装相应的软件包:

sudo apt-get install androguard python-networkx

反编译DEX文件:

$ androdd -i classes.dex -o ./dir-for-output

从Apk +反编译中提取classes.dex:

$ androdd -i app.apk -o ./dir-for-output

Apk文件就是Java的JAR文件，你可以通过以下方法从JAR文件中提取文件:

$ unzip app.apk -d ./dir-for-output

我用过

Dex2jar + jd-gui javadecompilers.com enjarify Apktool

但没有比谷歌自己的工具更好的了

1)Android Studio 2.x: 构建>分析apk

2)Android Studio 3.0: 配置文件或调试APK

我建议大家去这里看看: https://github.com/JesusFreke/smali

它提供了BAKSMALI，这是用于DEX文件的最优秀的逆向工程工具。 它是由JesusFreke制作的，他为Android创造了著名的rom。

您可以尝试JADX (https://bitbucket.org/mstrobel/procyon/wiki/Java%20Decompiler)，这是一个完美的DEX反编译工具。

是的，它也可以在线(my:0))新网站:http://www.javadecompilers.com/apk/

由于没有人提到这一点，还有一个工具:DED主页

安装指南和一些说明:安装。

它被用于一个非常有趣的关于顶级市场应用程序安全性的研究(不是真的相关，如果你好奇的话):Android应用程序安全性调查

下载APK文件后，您需要执行以下步骤以获得可编辑的java代码/文档。

Convert your apk file to zip (while start your download don't go with "save" option , just go with "save as" and mention your extension as .zip) by doing like this you may avoid APKTOOL... Extract the zip file , there you can find somefilename.dex. so now we need to convert dex -> .class To do that, you need "dex2jar"(you can download it from http://code.google.com/p/dex2jar/ , after extracted, in command prompt you have to mention like, [D:\dex2jar-0.09>dex2jar somefilename.dex] (Keep in mind that your somefilename.dex must be inside the same folder where you have keep your dex2jar.) Download jad from http://www.viralpatel.net/blogs/download/jad/jad.zip and extract it. Once extracted you can see two files like "jad.exe" and "Readme.txt" (sometimes "jad.txt" may there instead of "jad.exe", so just rename its extension as.exe to run) Finally, in command prompt you have to mention like [D:\jad>jad -sjava yourfilename.class] it will parse your class file into editable java document.
