Efficient Async with Kotlin Coroutines
summary
Shows practical Kotlin coroutines for Android: uses Retrofit returning Deferred/Response, demonstrates CoroutineScope tied to Activity with a Job cancelled in onDestroy so child coroutines stop, contrasts launch vs async (Deferred) and suspending functions vs Thread.sleep, uses withContext(Dispatchers.Main) and Dispatchers.IO, and points out IO can run 64+ coroutines concurrently. Delivers a working GitHub-API demo app, covers exception handling via CoroutineExceptionHandler, and proves coroutines reduce callback and threading boilerplate.
