What it is

RxAndroid is a lightweight Android-specific binding library for RxJava 3 that provides schedulers and utility classes to simplify reactive programming on the Android platform. It solves the critical Android problem of safely scheduling work on the main thread and background threads using RxJava's Observable/Scheduler pattern, enabling developers to write async code (like network requests) that emit results back on the UI thread without blocking. Single-module library structure: rxandroid/src/main/java/io/reactivex/rxjava3/android/ contains the core classes (AndroidSchedulers, HandlerScheduler, MainThreadDisposable, RxAndroidPlugins). Tests mirror this layout under…

Start here

Open these first:

• rxandroid/src/main/java/io/reactivex/rxjava3/android/schedulers/AndroidSchedulers.java — Primary entry point providing AndroidSchedulers.mainThread() — the core API that all Android RxJava developers use to…
• rxandroid/src/main/java/io/reactivex/rxjava3/android/schedulers/HandlerScheduler.java — Core scheduler implementation wrapping Android Handler/Looper; handles the actual dispatch of work to background threads or…
• rxandroid/src/main/java/io/reactivex/rxjava3/android/MainThreadDisposable.java — Base class for disposables that must be cleaned up on the main thread; essential for preventing memory leaks when RxJava…
• rxandroid/src/main/java/io/reactivex/rxjava3/android/plugins/RxAndroidPlugins.java — Plugin system for intercepting and customizing scheduler creation; allows testing and runtime instrumentation of all…
• rxandroid/build.gradle — Defines RxAndroid library dependencies (RxJava 3) and build configuration; essential for understanding what minimum SDK and…

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/ReactiveX/RxAndroid.git
cd RxAndroid
./gradlew build

Daily commands:

This is a library, not an executable. To use in a project: add implementation 'io.reactivex.rxjava3:rxandroid:3.0.2' to your Android app's build.gradle. To run the sample app: ./gradlew sample-app:build then open th…

Key cautions & unknowns

• Concentrated ownership — top contributor handles 61% of recent commits
• Robolectric required for testing: Unit tests use Robolectric (implied by test structure) to simulate Android Looper/Handler; must run on JVM with Robolectric shadow classes, not bare JUnit. **Version mismatch…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
