如果您不打算下载dex2jar，那么只需使用apk_grabber python脚本将任何apk反编译到jar文件中。然后使用jd-gui读取它们。

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

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.

很容易

获取这些工具:

Dex2jar将dex文件转换为jar文件 以查看jar中的Java文件

源代码可读性很强，因为dex2jar做了一些优化。

过程:

下面是如何反编译的过程:

步骤1:

将test_apk-debug.apk中的classes.dex转换为test_apk-debug_dex2jar.jar

d2j-dex2jar.sh -f -o output_jar.jar apk_to_decompile.apk
d2j-dex2jar.sh -f -o output_jar.jar dex_to_decompile.dex

注1:在Windows机器中，所有的.sh脚本都被.bat脚本取代

注2:在linux/mac上不要忘记sh或bash。完整的命令应该是:

sh d2j-dex2jar.sh -f -o output_jar.jar apk_to_decompile.apk 

注意3:另外，请记住向dex2jar-X添加执行权限。例如sudo chmod -R + X dex2jar-2.0
