## What it is
Booster is a lightweight, extensible quality optimization toolkit for mobile applications built as a Gradle plugin. It uses bytecode manipulation and static analysis to detect performance issues, optimize threading, fix system bugs, and reduce APK package size.

## Use cases
- detect performance issues like blocking I/O on the UI thread
- reduce APK package size by inlining resource indexes and compressing resources
- fix thread management problems causing OOM from too many threads
- globally patch system bugs like the Android API 25 Toast crash
- optimize app stability without modifying business code

## When to choose
- you build Android apps with Gradle and want non-intrusive build-time optimization
- you need to reduce APK size or improve stability metrics
- you want to detect or fix threading and performance issues across third-party SDKs
- you need an extensible SPI-based plugin architecture for custom bytecode transforms

## When to avoid
- your project does not use the Android Gradle Plugin
- you need runtime (not build-time) optimization
- you target platforms other than Android
- your build environment cannot meet the minimum Gradle/AGP/Kotlin version requirements

## Facets
- artifact type: framework
