Access 7000+ courses for 60 days FREE: In this 2 hour tutorial, you will learn everything you need to know about Coroutines in Kotlin using demos in IntelliJ IDEA and precise presentation. There are 5 chapters in this course. In chapter 1, get a solid understanding of what is #coroutine in #kotlin. - Explore the 'suspend' keyword, comparison with threads, delay function, function and a lot more. - Basics of coroutine builders: launch, async, and runBlocking. In chapter 2, dive deeper into Coroutine Builders and explore them in detail. - Use GlobalScope companion object to launch coroutines. - Why GlobalScope is discouraged to use? - Test suspending functions by writing a JUnit test case. In chapter 3, learn to cancel coroutines and handle exceptions. - What is cooperative coroutine? How to write a cooperative code? - Explore (), and () functions. - Use of yield() and delay() suspending functions (suspend modifier). - Explore what is boolean flag. - Handle CancellationException and TimeoutCancellationException. - Use withContext(NonCancellable), withTimeout, and withTimeoutOrNull coroutine builders In chapter 4, compose suspending functions in different ways within a coroutine. - Explore how code execution in coroutine is sequential by default. - How to execute suspending functions in a coroutine concurrently? - Lazily execute async coroutine by using In chapter 5, learn a few advanced coroutine concepts. - Understand what is CoroutineScope? - What is CoroutineContext? - What is a Dispatcher? - Role of a dispatcher: to assign a thread to a coroutine. - Types of Dispatcher: Confined, Unconfined, Default, Main, and IO - Components of CoroutineContext: Job, Dispatcher, and Coroutine Name.
