APKDecomp

Open-source agent skill · MIT licensed

Android binaries,
mapped with intent.

APKDecomp gives coding agents a disciplined route through APKs, bundles, DEX, resources, native libraries, and protected builds—without pretending one decompiler fits every target.

01 / THE METHOD

A workflow, not a
magic button.

Decompiler output is a hypothesis. The skill starts with evidence, chooses the layer that actually contains the app, and tells the agent when to cross-check.

01

Fingerprint before choosing

App era, compiler, splits, obfuscation, and framework determine the toolchain. The skill makes that decision explicit.

02

Inspect the right layer

DEX for Kotlin/Java. Native artifacts for Flutter or IL2CPP. Embedded bundles for React Native.

03

Cross-check, then report

When source output looks wrong, compare engines and return to smali—the closest static ground truth.

02 / DECISION PATHS

Follow the payload.

The package extension is only the container. APKDecomp routes analysis according to where behavior is implemented.

DEX / RESOURCES

Standard Android

Manifest, resources, Java/Kotlin-like source, and smali verification.

 MANAGED / CROSS-PLATFORM

Framework payloads

Flutter snapshots, React Native bundles, Xamarin assemblies, and Unity metadata.

 ELF / JNI

Native libraries

ABI selection, exported symbols, RegisterNatives, and C-like decompilation.

03 / OPERATING BOUNDARY

Careful by design.

Reverse engineering is dual-use. The skill keeps authorization visible and refuses workflows aimed at piracy, DRM bypass, or unauthorized tampering.
