    The mistake is that you use the wrong Observable. The correct code should be:

    Observable observable = Observable.create(new Observable.OnSubscribe() {
  @Override
  public void call(Subscriber subscriber) {
    int i = 0;
    while (i == 0) {}
    subscriber.onCompleted();
  }
});
observable.subscribeOn(Schedulers.newThread()).observeOn(AndroidSchedulers.mainThread()).subscribe();



    Both subscribeOn and observeOn return a new Observable which implements their functions. But the original Observable is not modified. Actually, every operator will always create a new Observable without modifying the original one.
