apktool-decompile

What problem does it solve?

Manually decompiling, modifying, and repackaging Android APKs is time-consuming and error-prone, especially when handling framework dependencies, multi-dex files, and APK signing requirements for testing and analysis.

Core Features & Use Cases

• Full APK Decoding: Converts APK files into readable resource files, smali bytecode, and extracts native libraries, with support for system framework files and multi-dex APKs.
• Modify and Repackage Workflows: Enables safe modification of smali code or resources, then rebuilds and signs the modified APK for testing or deployment.
• Helper Utilities: Includes pre-built scripts for quick APK analysis, targeted smali code search, and native library extraction to speed up reverse engineering tasks.
• Use Case: For example, if you need to test how an Android app behaves when a license check is bypassed, use this skill to decode the APK, modify the relevant smali method to always return true, repackage and sign the APK, then install it on a test device.

Quick Start

Use the apktool-decompile skill to decode the target Android APK file, modify its smali code or resources as needed, then rebuild and sign the modified APK for installation on a test device.
