Thank you so much, Kostya! Indeed it turns out to be an asynchronous call. It makes the design of the Activity slightly more verbose, but at least I got it working. Are there imperative reasons why the service is not returned synchronously? Is it very costly to (instantiate and) return a local Service? If not, it would be a nice feature to have the bindService block, or at least to have the option through a method parameter that we want to wait for it like bindService(..., boolean willWait).
Thanks again!
