Kotlin Flows and Channels for Android
summary
Compares Kotlin channels as nonblocking queues used for explicit send/receive with Flows as cold lazy streams that only run when collected, and argues Flows are safer and more resource efficient because channels are hot and can consume resources early. Demonstrates an Android app that builds a ListView of users by composing Room/retrofit-style sources into a repository and use case, using zip + map + onEach + flowOn and asLiveData or lifecycleScope collection, and it streams correctly in the demo.
