Smali
Smali is a two-way binary translation toolset designed to convert Dalvik bytecode to human-readable assembly and back again. It provides a mechanism for the disassembly and assembly of executable files used in virtual machine environments.
The project enables the modification of compiled Android application logic by transforming binary files into editable assembly and rebuilding them. It is used for reverse engineering, malware analysis, and the study of low-level instructions to identify program behavior or security flaws.
The toolkit covers binary construction through smali code assembly and detailed Dalvik analysis. This includes the translation of binary fields, method signatures, and type descriptors into text, as well as register allocation and the preservation of annotations and debug information during disassembly.
Features
