'Cancelling Coroutines in Kotlin' kotlin coroutinesinkotlin
Coroutines provide a simple undo mechanism to solve such problems and problems with long-running operations or memory leaks.suspend fun main=coroutineScope { val job=Job }
This Job object represents a running coroutine. Coroutines whose results we don't need can cancel anytime we want by calling thesuspend fun main=coroutineScope { val job=Job launch { repeat { i -> delay println } } job.cancel } The coroutine will be canceled without waiting for its actual completion. Calling cancel again does nothing.If we need to wait for the Job to be complete, we can use thesuspend fun main=coroutineScope { val job=Job launch { repeat { i -> delay println } } delay job.cancel job.join println }
