This is Nico Mexis' fork of the dex2jar project which aims to fix most issues.

• Fixed many StringIndexOutOfBoundsExceptions relating to signatures
• Fixed TypeTransformer related issues
• Fixed many NullPointerExceptions and other crashes
• Fixed grammar of error messages
• Update libraries (especially ASM)
• Library fat-jar can be used for other projects (Automatically produced by GitHub Actions)
• Smali now outputs .param instead of the outdated .parameter syntax
• Reformatted and cleaned up most of the code

This fork has builds available in the following formats.
You can also only depend on a single module, if needed. The following sections include all the modules.

The builds are available on Maven Central.

<dependency>
    <groupId>de.femtopedia.dex2jar</groupId>
    <artifactId>dex2jar</artifactId>
    <version>VERSION</version>
</dependency>

The builds are available on Maven Central.

implementation 'de.femtopedia.dex2jar:dex2jar:VERSION'

To download the latest builds, head to the Releases.

Note: The builds in Releases are automatically built by GitHub Actions.

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

1. dex-reader/writer: Read/write the Dalvik Executable (.dex) file. It features a lightweight API similar with ASM .
2. d2j-dex2jar: Convert .dex file to .class files (zipped as jar)
3. 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;"
4. other tools: d2j-decrypt-string

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

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

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

See for example the infamous Bytecode Viewer.
