Kotlin Coroutines

Introduction

Kotlin coroutines provide a powerful framework for asynchronous programming that is lightweight, expressive, and built on structured concurrency principles. Coroutines enable writing asynchronous code that looks and behaves like sequential code, eliminating callback hell and improving readability.

Unlike threads, coroutines are extremely lightweight—millions can run on limited resources. The coroutine framework includes suspend functions for non-blocking operations, builders for launching work, Flow for reactive streams, and comprehensive cancellation and exception handling mechanisms.

This skill covers coroutine fundamentals, builders, contexts, Flow, channels, and production patterns for Android development and server-side Kotlin.
