## What it is
A drop-in replacement for android.os.Handler that holds weak references to posted Runnables and Messages, preventing memory leaks. It is a small Java library for Android published via JitPack by Badoo.

## Use cases
- avoid memory leaks from postDelayed runnables holding activities
- replace android.os.Handler with a memory safer version
- post delayed runnables without leaking fragments
- fix handler leaks flagged by Android lint
- keep scheduled UI tasks collectible by garbage collector

## When to choose
- your Android app posts delayed runnables from activities or fragments
- lint or LeakCanary reports Handler-related memory leaks
- you want a drop-in Handler replacement with minimal code changes

## When to avoid
- you need runnables guaranteed to execute even if unreferenced elsewhere
- your project is not on the Android/JVM platform
- you need a maintained solution with active development and broad community support

## Facets
- artifact type: library
- maturity: maintenance
- function: concurrency, developer-tools
- domain: android-tools, mobile-development, developer-tools
- platform: jvm
- tags: android, memory-leaks, weak-references, handler, jitpack, mobile
