Launching Into Coroutines

on YouTube ↗49m

" summary

Kotlin coroutines replace callback spaghetti with suspend/resume and integrate with Retrofit so network calls look like direct calls while running on Dispatchers.IO and CPU work runs on Dispatchers.Default leaving the UI on Dispatchers.Main. Structured concurrency enforces that a suspend function only returns after its child coroutines finish, scopes cancel their children and report exceptions. Testing support lands in kotlinx-coroutines-test. Examples show background save patterns, ViewModel scope usage, and pitfalls around unstructured launches and leaked work.
