Real-Time Communication in Android

on YouTube ↗14m

" summary

Shows a Kotlin Multiplatform Android app talking to a ketor backend using HTTP, SSE and WebSockets, with a Compose UI offering three buttons for REST, SSE and WebSocket. Demo sends the server time every second over SSE (unidirectional) and uses coroutines, shared flow and an atomic integer to broadcast bidirectional WebSocket messages between two web clients and the Android client. Implements server SSE plugin (ketor 3.0 beta) and works: REST returns a hello, SSE streams ticks, WebSocket sends and receives live updates.
