Covers core reactive fundamentals (hot vs cold streams, backpressure, operator categories), detailed pros/cons of each library, and concrete side-by-side code migration scenarios: EventBus to SharedFlow, RxJava Observables to cold Flow, and BehaviorSubject to StateFlow. Also covers interoperability via kotlinx-coroutines-rx3, testing with Turbine, and a migration checklist with lifecycle-safe collection patterns. ## Full article daily.dev links to this article rather than hosting it.

I migrated a few RxJava-heavy screens to Flow recently, and StateFlow + lifecycle-aware collection ended up removing a lot of boilerplate while making state handling easier to reason about. **@mark\_kazakov** · 1 upvotes > A very good tutorial, thanks for sharing ## Similar posts on daily.dev - [Mastering Coroutines and Flow in Android](https://daily.dev/posts/mastering-coroutines-and-flow-in-android-opgwyvoqn) · Medium · 0 upvotes · 0 comments --- Tags: [#java](https://daily.dev/tags/java), [#android](https://daily.dev/tags/android), [#reactive-programming](https://daily.dev/tags/reactive-programming) [View this post on daily.dev](https://daily.dev/posts/android-reactive-streams-eventbus-rx-kotlin-flow-iczy0yqg8)
