What error management methods are applicable in coroutines?

Answer from AI
In Android coroutines (using Kotlin Coroutines), the following methods are used for error handling:
- try-catch inside a coroutine — the standard way to handle exceptions.
try {
// coroutine code
} catch (e: Exception) {
// error handling
}
- CoroutineExceptionHandler — a special exception handler that can be passed into the coroutine context for global unhandled exception handling.
val handler = CoroutineExceptionHandler { _, exception ->
println("Caught $exception")
}
GlobalScope.launch(handler) {
// code
}
-
supervisorScope and SupervisorJob — allow isolating errors in child coroutines so that one error does not cancel all others.
-
Error handling in Flow — using
catch {}operators to handle exceptions in data streams.
Thus, the choice of method depends on the context and whether local or global error handling is needed.
