## What it is
RxLifecycle is a Java library for Android that automatically completes RxJava reactive sequences based on a lifecycle stream, preventing memory leaks from incomplete subscriptions. It provides binding APIs and provider components for Activities, Fragments, and Android's Architecture Components lifecycle.

## Use cases
- prevent memory leaks from RxJava subscriptions in Android activities
- automatically complete observables when an Android activity is destroyed
- bind reactive streams to Android fragment lifecycle events
- terminate RxJava sequences on specific lifecycle events like DESTROY
- use RxJava with Android Architecture Components LifecycleOwner
- manage RxJava subscriptions in Kotlin Android apps

## When to choose
- you use RxJava in Android apps and need lifecycle-aware subscription management
- you want to avoid memory leaks from long-running observables outliving activities or fragments
- you prefer declarative binding of streams to lifecycle events rather than manual unsubscribe calls

## When to avoid
- you use Kotlin coroutines or Flow instead of RxJava
- you need actual unsubscribe behavior rather than sequence termination
- your project is not Android/JVM based
