Answer from AI
Dispatchers.Default in Kotlin coroutines is a dispatcher designed for executing CPU-intensive tasks in a thread pool optimized for multithreaded processing.
It is used when you need to perform calculations that should not block the main (UI) thread but still require significant processor resources.
Example of usage:
GlobalScope.launch(Dispatchers.Default) {
val result = heavyComputation()
withContext(Dispatchers.Main) {
updateUI(result)
}
}
Here, heavyComputation() runs in the Default thread pool, and UI updates happen on the main thread.
