Yes

Example

            compositeDisposable.add(APIClient.getOpenEventAPI().getDiscountCodes()
                    .subscribeOn(Schedulers.io())
                    .observeOn(AndroidSchedulers.mainThread())
                    .subscribe(discountList -> {
                        Timber.i("Downloaded Discount Codes");
                        realmRepo.saveDiscountCodes(discountList).subscribe();
                        discountCodesDownloadResponse.setValue(true);
                    }, throwable -> {
                        Timber.i("Discount Codes download failed");
                        discountCodesDownloadResponse.setValue(false);
                    }));
        } catch (Exception e) {
            Timber.e(e);
        }```
this is taken from discountVM similar issue can be found in some other VM's too
