CoroutineScope in Kotlin is used to manage the lifecycle of coroutines. It defines the scope within which coroutines are launched and allows control over their cancellation and completion.
Main tasks of CoroutineScope:
- Grouping of coroutines: all coroutines launched within the same scope are related.
- Lifecycle management: when the scope is canceled, all coroutines within it are automatically canceled, helping to prevent memory leaks and uncontrolled execution.
Example of usage:
val scope = CoroutineScope(Dispatchers.Main)
scope.launch {
// coroutine code
}
// Later, you can cancel all coroutines in the scope
scope.cancel()
In Android, lifecycleScope or viewModelScope are often used, which are automatically canceled when the corresponding component (Activity, ViewModel) is destroyed.
