## What it is
AabResGuard is a tool from ByteDance's Douyin Android team that obfuscates resources inside Android App Bundle (AAB) files to shrink package size. It works as both a command-line tool and a Gradle plugin, supporting duplicate resource merging, file filtering, whitelisting, and incremental obfuscation via mapping files.

## Use cases
- obfuscate resources in an android app bundle
- reduce aab package size by merging duplicate resources
- filter unnecessary files like native libs from an aab
- incrementally obfuscate aab resources using a mapping file
- remove unused strings from an android bundle
- protect android resource names from reverse engineering

## When to choose
- you ship android app bundles and want smaller download sizes
- you need resource name obfuscation with whitelist control
- you want aab obfuscation integrated into your gradle build

## When to avoid
- you build with APKs instead of AABs (use AndResGuard instead)
- you need actively maintained tooling - the latest release is from 2021
- you target newer bundletool versions that may be incompatible
