Chapter 3: Handling Coroutine Cancelations and Exceptions

In the previous chapter, you dove deep into Kotlin coroutines and learned how to use them for asynchronous programming in Android with simple code. You learned how to create coroutines with coroutine builders. Finally, you explored coroutine dispatchers, coroutine scopes, coroutine contexts, and jobs.

Coroutines can be canceled when their purpose has been fulfilled or their job has been done. You can also cancel them based on specific instances in your app, such as when you want users to manually stop a task with a tap of a button. Coroutines do not always succeed and can fail; developers must be able to handle these cases so that the app will not crash, and they can inform the users by displaying a toast or snackbar message.

In this chapter, we will start by understanding coroutine cancelation. You will learn how to cancel coroutines and handle cancelations and timeouts for your coroutines. Then, you will learn how to...
