Decompiler Solutions
Solution 1 - Decompiler
Follow the below steps to do so_
>1. Rename your APK file(e.g., rename your APK file to .zip Ex- test.apk -> test.zip) & extract resultant zip file. 2. Copy your .dex file in to dex2jar folder.
- Run setclasspath.bat. This should be run because this data is used in the next step.
- Go to Windows Command prompt, change the folder path to the path of your dex2jar folder and run the command as follows: d2j-dex2jar.bat classes.dex
- enjoy!! Your jar file will be ready in the same folder with name classes_dex2jar.jar.
Hope this helps you and All reading this... :)

Solution 5 - Decompiler
- old link
- the link http://code.google.com/p/dex2jar/downloads/list is old, it will redirect to https://github.com/pxb1988/dex2jar
- dex2jar syntax
- in https://github.com/pxb1988/dex2jar, you can see your expected usage/syntax:
sh d2j-dex2jar.sh -f ~/path/to/apk_to_decompile.apk
- can convert from
apk
tojar
.
- want
dex
tojar
- if you have
dex
file (eg. usingFDex2
dump from a running android apk/app), then you can: sh d2j-dex2jar.sh -f ~/path/to/dex_to_decompile.dex
- can got the converted
jar
fromdex
. - example:
/xxx/dex-tools-2.1-SNAPSHOT/d2j-dex2jar.sh -f com.huili.readingclub8825612.dex dex2jar com.huili.readingclub8825612.dex -> ./com.huili.readingclub8825612-dex2jar.jar
- want
jar
tojava src
- if you continue want convert from
jar
tojava sourcecode
, then you, have multiple choice: * usingJadx
directly convertdex
tojava sourcecode
* first convertdex
tojar, second convert
jarto
java sourcecode`
Note
d2j-dex2jar.sh
?
how to got download from dex2jar github release, got dex-tools-2.1-SNAPSHOT.zip, unzip then got
- you expected Linux's
d2j-dex2jar.sh
- and Windows's
d2j-dex2jar.bat
- and related other tools
d2j-jar2dex.sh
d2j-dex2smali.sh
d2j-baksmali.sh
d2j-apk-sign.sh
- etc.
- and Windows's
dex
to java sourcecode
?
what's the full process of convert you can refer my (crifan)'s full answer in another post: android - decompiling DEX into Java sourcecode - Stack Overflow
or refer my full tutorial (but written in Chinese): 安卓应用的安全和破解
