dxcut is a library for reading, editing, and writing dex and odex files which contain the class definition and Dalvik bytecode used by the Android operating system. This project includes a disassembler/decompiler, dex optimizer, and hooking utils.
Java decompiler written in C++ aimed to decompile Java 6.0 (and below) class files. The intention of the decompiler is to generate source files using as much information provided in the class file as possible.
