skylot/jadx

Jadx is a comprehensive reverse engineering tool for Android applications, providing a graphical interface and command-line tools to decompile, analyze, and debug APK, AAB, and Dex files. The system features a modular plugin architecture that supports custom inputs, code generation, and security analysis, alongside advanced capabilities like call graph visualization, Smali debugging, and automated deobfuscation. It enables users to export decompiled code as structured Java or Android projects, manage plugin ecosystems, and persist user preferences and cache data for improved performance.

This period was defined by a comprehensive architectural overhaul of the Jadx core, introducing a modular, type-safe AST and region-based control flow representation. The team implemented a new type inference engine, enhanced deobfuscation capabilities, and added support for Android resources and Gradle project exports. These structural improvements were accompanied by a massive expansion of integration tests to ensure the accuracy of the decompiled output.
