I have the exact same problem. I get a NullPointerException when I want to
extract the service with a specific serviceReference:
ref = bc.getServiceReference(sb[j].toString());
Log.d("REF", ref.toString());
Object service = bc.getService(ref);
It does not even get to the 3rd line of code... Does anybody have an idea
why? The service appears to be registered.
