Model View Intent, Embracing Reactive UI's
summary
Argues MVI as Intent → Model → View with user actions and lifecycle represented as Rx streams, using state reducer functions and Rx scan to produce an immutable view state stream; uses Dagger for wiring, RxBindings to turn UI events into streams, and Conductor for lifecycle events. Demonstrates a to‑do app that intentionally fails ~30% of requests and supports per‑item retry, claims easier unit testing, clearer event tracing, fewer bugs, and a working GitHub prototype.
