Kotlin Coroutines provide several powerful concurrency primitives, but when you need direct communication between coroutines, Channels become the tool of choice. While Flow is excellent for reactive streams and UI/data […]
Kotlin Coroutines and Flow have fundamentally reshaped how modern Android applications are designed. They did not simply replace callbacks or RxJava operators — they introduced a different way of thinking […]
Kotlin Flow often gets introduced as “RxJava but simpler” or “LiveData replacement.” That framing is convenient, but it hides what actually makes Flow powerful: This article targets middle–senior Android/Kotlin developers. […]
Kotlin Coroutines give developers powerful tools for writing asynchronous, concurrent, and structured code. But behind every coroutine—behind its dispatcher, its cancellation behavior, its exception handling, and even its name—lies one […]
If you have been using Kotlin Coroutines for a while, you have probably experienced at least one of these situations: These problems do not come from “wrong syntax”.They come from […]
Concurrency is not difficult because we don’t know how to run code in parallel.It is difficult because we don’t know when that code should stop, who owns it, and what […]
If you’ve been working with Kotlin long enough—especially on Android or backend services—you’ve almost certainly written suspend fun.Yet many experienced developers still describe suspend functions as “functions that run asynchronously” […]
Kotlin Coroutines are “easy” until they aren’t. Most production issues I’ve debugged weren’t caused by coroutines themselves, but by wrong assumptions about dispatchers, threads, and “blocking”. This post is a […]
What Are Builders? Coroutine builders are creation mechanisms that define how a coroutine starts, what it returns, how it behaves, and how it participates in structured concurrency.Using the correct builder […]
Kotlin Coroutines are no longer just a “nice-to-have” — they are the standard way to write asynchronous, concurrent code in modern Kotlin projects, whether you’re building Android apps, Ktor/Spring backends, […]
