## What it is
Apktool is a Java-based command-line tool for reverse engineering Android APK files. It decodes resources and manifest files to nearly original form, disassembles dex to smali, and rebuilds modified apps back into installable APKs.

## Use cases
- decompile an apk to inspect its manifest and resources
- translate or localize an android app by editing its resources
- debug smali code step by step
- rebuild a modified apk after changing resources or permissions
- analyze a closed-source android app's structure
- extract assets and resources from an apk

## When to choose
- you need to decode and re-encode Android binary resources and manifests
- you want to disassemble dex to readable smali and rebuild the apk
- you need a mature, widely used tool for apk reverse engineering on any OS

## When to avoid
- you need full Java decompilation to source code rather than smali
- you only want to install or run apks, not inspect or modify them
- you need to analyze iOS or non-Android binaries

## Facets
- artifact type: cli-tool
- maturity: stable
- function: reverse-engineering, parser, cli, developer-tools
- domain: reverse-engineering, android-tools, security, developer-tools, mobile-development
- platform: cli, cross-platform, jvm, windows
- tags: apk, smali, dex, android-resources, decompilation, apk-repackaging, java, linux, macos
