Modules

Tools to work with android .dex and java .class files

dex-reader/writer: Read/write the Dalvik Executable (.dex) file. It features a lightweight API similar with ASM .
d2j-dex2jar: Convert .dex file to .class files (zipped as jar)
smali/baksmali: Disassemble dex to smali files and assemble dex from smali files. Different implementation to smali/baksmali, same syntax, but we support escape in type desc "Lcom/dex2jar\t\u1234;"
other tools: d2j-decrypt-string

Usage

In the root directory run: ./gradlew distZip
cd dex-tools/build/distributions
Unzip the file dex-tools-2.4-SNAPSHOT.zip
Run d2j-dex2jar.sh from the unzipped directory

Example usage:

sh d2j-dex2jar.sh -f ~/path/to/apk_to_decompile.apk

And the output file will be apk_to_decompile-dex2jar.jar.

Example Maven project:

See for example the infamous Bytecode Viewer.
