Android: is it possible to use Firebase Remote Config in a background service?

I would like to use Firebase Remote Config in a background service (that I used to display notifications). Is it possible to do this ?

To be more accurate, is it possible to fetch the remote values in a background service ?

// Code below in a background service ?
mFirebaseRemoteConfig.fetch(cacheExpiration).addOnCompleteListener(this, new OnCompleteListener<Void>() {

    @Override
    public void onComplete(@NonNull Task<Void> task) {
             // get remote values here            

    }
 }

Thanks !!!
