Cancellation
Explore the fundamental concepts of cancellation in Kotlin coroutines. Understand how to use the Job interface's cancel method, why cancellation is safer than killing threads, and how to properly handle coroutine lifecycle with cancelAndJoin. Gain insights into managing coroutine groups and avoiding race conditions to ensure resource cleanup and smooth app behavior.
We'll cover the following...
An essential functionality of Kotlin coroutines is cancellation. It is so vital that some classes and libraries use suspending functions primarily to support cancellation. There is a good reason for this: a suitable cancellation mechanism is worth its weight in gold. It’s worth much more since the code is currently not very heavy (it used to be, when we stored it on punched cards). Just killing a thread is a terrible solution as there should be an opportunity to close connections and free resources. Forcing ...
