If you’re a mid-level developer, you probably have a solid grasp of Kotlin basics, coroutines, and maybe even some experience with Flows. But if you’ve ever struggled with integrating legacy […]
Kotlin Coroutines are powerful, flexible, and expressive. They make asynchronous programming easier than older techniques like callbacks, AsyncTask, or RxJava. But like any concurrency tool, coroutines can become slow, inefficient, […]
Testing coroutine-based code is one of the most important skills for Android and Kotlin developers. Coroutines introduce asynchronous execution, background work, Flow streams, delays, and lifecycle–all of which make testing […]
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” […]
