Coroutine scopes are a crucial concept in Kotlin coroutines as they define the lifetime and cancellation behavior of coroutines. Let me provide a more detailed explanation of the different types of scopes you can use in Android development. This is the basic scope interface that you can implement or instantiate directly: // Creating a custom … Read more
When it comes to handling asynchronous tasks, coroutines are a hot topic in Android development.š„ Many developers may use them regularly but might miss out on some subtle behaviors. I put together this quick 11-question quiz to help you check your understanding. Hope you enjoy it!š 1. What happens when a child coroutine inside a … Read more
Diagram from kotlinlang.org ā¢ Coroutines are lightweight threads in Kotlin, designed for asynchronous and non-blocking programming. They help perform long-running tasks like network calls, without freezing your app. ā¢Simplify asynchronous code. – Avoid callback hell. – Lightweight and efficient. – Structured concurrency for lifecycle safety. ā¢ Example: runBlocking { launch { delay(1000) println(āWorld!ā) }println(āHello,ā)} Output: … Read more

Structure your Android app with clear, testable, and coroutine-ready use cases. Introduction Earlier, we developed an Android application with a focus on Clean Architecture, Inputs/Outputs MVVM splitting, and the Repository pattern. This approach follows best practices recommended by the Android team at Google, making the codebase scalable, maintainable, and testable.In this article, weāll dive into … Read more

Photo by Markus Winkler onĀ Unsplash Introduction When working with Kotlin coroutines, one of the most common sources of confusion is the difference between cancelling a specific Job and cancelling an entire CoroutineScope. They sound similarāāābut their behavior is very different. In this article, weāll break it down clearly, with real-world analogies and code examplesāāāso youāll … Read more
In modern Android development, Kotlin Coroutines has become the go-to solution for writing asynchronous, non-blocking code. However, one fundamental piece that powers coroutine behavior is the job, which is a handle to manage and control coroutine execution. What is a Job in Kotlin Coroutines? A Job is a cancellable handle for a coroutine. It tracks … Read more
Debugging asynchronous code is difficult, as it can be hard to capture its true nature while putting regular breakpoints in debugging. Here are a few options to keep a coroutineās true nature: Options available for IntelliJ IDEA Logging Run/Debug Configurations GUI Debugging Options available for Android Studio Logging Experimental Coroutine Debugging in Test Letās get … Read more
In traditional programming, execution flow is structured around a main routine (the entry point of the program) and subroutines (helper functions that perform specific tasks). What is a Main Routine? The main routine (often called main()) is: The entry point of every program. The first function that executes when you run your code. Responsible for … Read more
