## What it is
Frodo is an Android library that logs RxJava Observables and Subscribers to logcat via annotations like @RxLogObservable and @RxLogSubscriber. It weaves debug code only into debug builds using an annotation-based Gradle plugin, inspired by Jake Wharton's Hugo.

## Use cases
- log rxjava observable emissions during debugging
- trace subscriber onnext onerror oncompleted events in logcat
- debug which schedulers an observable runs on
- add debug-only logging annotations safe for production code
- measure execution time of reactive streams on android

## When to choose
- you maintain a legacy Android project using RxJava 1.x and want annotation-based stream logging
- you want debug logging that is automatically stripped from release builds

## When to avoid
- your project uses RxJava 2/3 or Kotlin coroutines/Flow instead of RxJava 1
- you need an actively maintained library or a permissive license (none is specified)
- you prefer modern debugging tools like RxJava debug plugins or Stetho

## Facets
- artifact type: library
- maturity: abandoned
- function: logging, middleware
- domain: android-tools, developer-tools
- platform: jvm
- tags: rxjava, debug-builds, annotation-processing, logcat, reactive-programming, debugging, android
