abc-decompiler

Decompiler for HarmonyOS Ark bytecode (.abc), the format HarmonyOS app packages carry in modules.abc, built by adapting the jadx decompiler and reading files through a patched copy of the abcde library. Because much of Ark bytecode is semantically close to DEX, it reuses jadx's GUI, IR and passes: an .abc file dropped into the jadx-based window is shown as decompiled code. The README reports that all 227 usable instructions of the 282 Ark opcodes are implemented, most special instructions as pseudo-functions.

Requirements & limits

  • The README describes the project as still in development: decompilation passes for more readable output, a custom IR and data-flow analysis are listed as unfinished. The only release, h1, published 2024-12-20, ships a single jadx-dev-all.jar built from the reviewed master commit, and the repository has had no pushes since.
  • Building needs JDK 17+; the patched abcde fork must first be published to the local Maven repository and its version substituted into the Gradle files before ./gradlew dist. Input is the modules.abc file from the user's own HarmonyOS HAP package.
  • The repository is a modified jadx code base: jadx's DEX input, test samples and inherited CI files remain, and it has no GitHub Actions workflow of its own, so no tests of Ark bytecode output are reported.
  • Apache-2.0, as inherited from jadx; the abcde fork is also Apache-2.0. No files were decompiled.
