Networking the Kotlin way: Retrofit + Coroutines
summary
Claims that Retrofit pairs with Kotlin coroutines to replace RxJava for typical single-request networking, shows Retrofit supporting suspend functions (Retrofit 2.5-1 snapshot), demonstrates using Dispatchers.IO and Dispatchers.Main for thread control, and explains migration patterns: replace Single/Completable with Deferred or suspend, use launch/async/runBlocking builders, and wrap parallel calls in coroutineScope with async/await to get structured cancellation. Gives testing guidance using kotlinx-coroutines-test to override the Main dispatcher, touts thousands-of-coroutines lightweightness, and shows debugging and ViewModel scope auto-cancel behavior.
