Apktool vs Hiew

Apktool is a command-line tool for reverse engineering Android APK files. It can disassemble an app’s resources into a form close to their original structure, then rebuild an app after changes such as translation or permission edits. Its analysis mode attempts to extract resources and the manifest for inspection without rebuilding. Apktool runs on Windows, Linux, and macOS; its official installation guide describes wrapper-script steps for those systems and requires Java 8 or later. Decode options include choosing resource-resolution behavior, skipping resources or source disassembly, and setting a framework directory. Build options include selecting an aapt2 binary, adding a generic Network Security Configuration file, and disabling APK repacking. The Apache license permits redistribution, modification, and integration into another project. Apktool is free, with no pricing tiers stated. Its FAQ says Android devices are not officially supported, and some OEM-modified “Magic APKs” may not decode or build. Builds are unsigned; copying a signature retains only the original APK signature v1 scheme.

Hiew is a Windows console program for viewing and editing files of unlimited size in text, hex, and disassembler modes. Its maker describes it as a classic since 1991. Disassembly includes x86-64 with AVX instruction support and an ArmV6 disassembler. Listed executable formats include NE, LE, LX, PE/PE32+, little-endian ELF and ELF64, Mach-O, and TE/TE64. Users can follow direct calls and jumps with a click and search instruction patterns in disassembler mode. Other listed capabilities include block operations, multi-file search and replace, keyboard macros, Unicode and UTF-8, binary templates, scripting, disk editing, plugins, and HEM modules. The free demo omits editing, crypt, assembler, 64-bit and ARM disassembly, drive support, keyboard macros, and HEM support, among other restrictions. The single-version license costs $25 as a one-time purchase with no updates. Lifetime updates cost $249 as a one-time purchase; Hiewix 32-bits costs $59, paid once with free 1-year updates.
