what will happen with this code, does it crash app or pass the exception down to onError()

val testNulls = Observable.create<String> {
        throw NullPointerException()//case 1
//        it.onNext(null!!) // case 2
        it.onNext("Ahmed")
    }

Best way to find out is to test it, but I'd expect it to pass the initial NPE to the onError block

I believe it will go to the uncaught handler

[Mohamed Ibrahim]

well I did a test and throwing NLP in create() will just pass the exception to onError()

[Mohamed Ibrahim]

but if you tried to pass Null as a value it will crash the stream
