## What it is
Hugo is an Android library and Gradle plugin that adds automatic method call logging via a @DebugLog annotation. It logs method entry with arguments, return values, and execution time, only in debug builds with zero effect on release builds.

## Use cases
- log method calls with arguments and return values in Android apps
- measure how long methods take to execute during debugging
- add debug tracing without polluting release builds
- replace manual log statements around method bodies
- toggle method logging at runtime while debugging

## When to choose
- you develop Android apps in Java and want zero-effort debug logging
- you want method timing and argument logging that never ships in release builds
- you prefer annotation-driven instrumentation over manual log statements

## When to avoid
- your project is Kotlin-first or uses modern tooling the plugin may not support
- you need production or release-build logging
- you need structured or centralized logging rather than simple method tracing
- you need a actively maintained solution for new Android Gradle Plugin versions
