Procedure for decoding .apk files,
step-by-step method:
Step 1:
Make a new folder and put .apk file in it
(which you want to decode). Now rename the extension of this .apk file to .zip
(eg.: rename from filename.apk to filename.apk.zip) and save it. Now you get
classes.dex files, etc. At this stage you are able to see drawable but not xml
and java files, so continue.
Step 2:
Now extract this zip apk file in the same
folder (or NEW FOLDER). Now download dex2jar from this link http://code.google.com/p/dex2jar/
and extract it to the same folder (or NEW FOLDER). Now open command prompt and
change directory to that folder (or NEW FOLDER). Then write dex2jar classes.dex and press enter. Now you get classes.dex.dex2jar file in the same
folder. Then download java decompiler from http://java.decompiler.free.fr/?q=jdgui
and now double click on jd-gui and click on open file. Then open
classes.dex.dex2jar file from that folder. Now you get class files and save all
these class files (click on file then click "save all sources" in
jd-gui) by src name. At this stage you get java source but the xml files are
still unreadable, so continue.
Step 3:
Now open another new folder and put these
files
1.
put .apk file which you want to
decode
2.
download apktool v1.x AND
apktool install window using google and put in the same folder
3.
download framework-res.apk file
using google and put in the same folder (Not all apk file need
framework-res.apk file)
4.
Open a command window
5. Navigate to the root directory of APKtool and type the following
command: apktool if
framework-res.apk
6.
apktool
d "fname".apk ("fname"
denotes filename which you want to decode)
now you get a file folder in that folder
and now you can easily read xml files also.
Step 4:
It's not any step just copy contents of
both folder(in this case both new folder)to the single one
and now enjoy with source code...

Reference:
功能
- 集成apktool/dex2jar/jd-gui
- 只需执行一步即可反编译出apk所有文件(资源文件和jar等等)
- 打开jd-gui反编译jar文件
使用方法
- 在Downloads中下载onekey-decompile-apk.zip, 解压缩到类似D:\downloads\onekey-decompile-apk
- 将apk文件放到onekey-decompile-apk目录下
- 将apk文件拖拽到_onekey-decompile-apk.bat上
- 执行完成后
- 会在onekey-decompile-apk目录下生成和apk同名的目录(放置了apktools反编译出来的东西)
- 会在onekey-decompile-apk目录下生成和apk同名的jar文件(dex2jar反编译出来的class)
运用工具(非常感谢他们)
- apktool反编译出apk中的资源文件, 例如AndroidManifest.xml和res
- dex2jar反编译出apk中的class
- jd-ui/jad反编译class为java源文件
java -jar apktool.jar d -d xxx.apk
// dex2jar is deprecated, use the d2j-dex2jar d2j-dex2jar xxx.apk
反编译工具还是jad最强, JD-GUI只是方便反编译/查看整个jar而已, 反编译出来的代码不全, 因此需要jd + jad(或者jadclipse eclipse插件使用更方便)配合才完美
