Claude Code skill for Android APK reverse engineering — apktool, jadx, Frida workflows.

A skill bundle that teaches Claude how to do real Android reverse engineering: unpack APKs, decompile to Java with jadx, patch smali, hook with Frida. It chains the right tools instead of one-shotting jadx and giving up.

Why use it

Key features

End-to-end workflow: pull APK → unpack → decompile → search → patch → repack → sign
Frida script scaffolding for runtime hooks
Smali patching with checksum-safe repack
Built-in checklists for common targets (cert pinning, root detection)
Pairs with a bin/ toolchain bootstrap

Use Cases

Real-world ways to use Android Reverse Engineering Skill

Bypass cert pinning on a test app for MITM analysis

👤 Security researchers (with permission!) ⏱ ~15 min intermediate

When to use: You need to inspect a Flutter/OkHttp app's traffic and pinning blocks Burp.

Prerequisites

Server/skill installed and authenticated — See repo README

Flow

Identify pinning

Decompile target.apk and find all references to TrustManager / CertificatePinner / Flutter's HttpClient.✓ Copied

→ List of hooks to patch
Patch + Frida

Generate a Frida script that no-ops checkServerTrusted across both Java and Flutter paths.✓ Copied

→ Frida .js + run command

Outcome: Working MITM channel on a test target you own.

Pitfalls

Reversing apps you don't have rights to is illegal in most jurisdictions. The skill assumes you've documented authorization. — Reversing apps you don't have rights to is illegal in most jurisdictions. The skill assumes you've documented authorization.

Cost & Limits

What this costs to run

API quota: See provider docs for rate limits
Tokens per call: Varies by tool
Monetary: See repo README for pricing details
Tip: Cache tool results and avoid repeated identical calls.

Security

Permissions, secrets, blast radius

Credential storage: Use environment variables; never commit secrets

Data egress: Tool calls go to the provider's API as documented

Troubleshooting

Common errors and fixes

apktool fails to unpack

Use the latest apktool (≥2.9). Older versions miss new resource tables.

Verify: apktool --version ≥ 2.9

repack signs but won't install

Use uber-apk-signer with --allow-resign and target the right SDK level.

Verify: adb install -r app-signed.apk
