I would guess that you failed to supply two arguments to Log.d(<tag>, <message>), or that you aren't looking for the message using logcat, but expecting it to show up somewhere else.
Otherwise, your question is too unclear to answer. You CAN use sockets to communicate with your computer. That, or any failure to do so, has nothing to do with what your app displays, and I have no idea why you mentioned it. You could try making your socket code work in plain Java on your computer, and then trying it on the phone. If you're using the emulator rather than a phone, be sure to read the documentation for the emulator.
