Chapter 2: Understanding Kotlin Coroutines

In the previous chapter, you revisited the concept of asynchronous programming and how it helps you execute long-running tasks in the background without freezing the app and annoying your app’s users. You learned how to carry out asynchronous programming with Threads, AsyncTasks, and Executors. Finally, you were introduced to the new way of doing it on Android: Kotlin Coroutines and Flows.
