## What it is
A Java annotation processor for Android that generates Builder classes and argument injection code for Fragments at compile time, avoiding reflection. It eliminates boilerplate and crash-prone manual argument handling in Fragment-based Android apps.

## Use cases
- pass arguments to android fragments safely
- avoid NullPointerException on fragment arguments after rotation
- generate fragment builders instead of writing newInstance boilerplate
- inject fragment arguments without reflection
- reduce boilerplate in android fragment code

## When to choose
- you maintain a legacy Android app using Fragments and want type-safe argument handling
- you want compile-time generated builders with no reflection overhead
- you frequently hit crashes from unset fragment arguments across configuration changes

## When to avoid
- you build new apps with Jetpack Compose or Navigation Component's Safe Args
- your project uses Kotlin with modern fragment argument solutions
- you need actively maintained tooling - the project sees only sporadic releases

## Facets
- artifact type: library
- maturity: maintenance
- function: developer-tools, boilerplate
- domain: mobile-development, android-tools, developer-tools
- platform: jvm
- tags: annotation-processor, fragments, android, compile-time-codegen, no-reflection, code-generation
