I have an exceptionHandler passed to the the scope.launch and based on a certain exception I want to stop the coroutine and then restart it. Is this the correct way to achieve it?

I don't think you need to cancel the job, because when an exception occurs that has already happened (you can't stop the cancellation by using a handler). additionally, you can't reuse a job once it's been cancelled/finished

So would I need to create a new instance of the job?
job = Job() and/or create a new instance of the scope? scope = CoroutineScope(dispatcher + job) and then call the coroutineMethod?

I don't think you need `job` at all -- create your scope with `SupervisorJob()` so it doesn't get cancelled on exception. you don't need the `isActive` check for the `while` loop because `delay` is already cancellable iirc (check docs), and you don't need to cancel a job in your handler

Regarding delay, I want to run the coroutine every 4 seconds to make the api call.

I want the coroutine to stop execution after an exception, dosomething and then restart
