I've been trying to build my own plugin for the service framework and I got it working with S60 5th edition emulator. It does not work on the device though. Then I checked with ServiceBrowser example and it seems that on device (N97 Mini) addService() fails every time, because list of services in serviceBrowser example is always empty. In emulator I got my own plugin to be visible on that list and it seems to work in the actual application as well. Any suggestions what might be wrong?
