dex2jar
Apache-2.0🧬 Reverse Engineering · Java
dex2jar is a set of tools for working with Android's DEX (Dalvik Executable) format and Java CLASS files. Its primary function is converting APK/DEX files to JAR format, enabling analysis with standard Java decompilation tools like JD-GUI or Procyon. The toolset includes d2j-dex2jar (DEX to JAR conversion), d2j-jar2dex (reverse conversion), d2j-smali/baksmali (assembler/disassembler), and d2j-decrypt-string (string decryption helper). It handles multi-DEX APKs and provides better conversion quality than alternatives for certain obfuscation patterns. A fundamental tool in the Android reverse engineering pipeline.
