Found the problem on 2.3 in the emulator at least. It works if I add
urlConnection.setRequestProperty("Content-Type", "application/x-www-
form-urlencoded");
after the urlConnection.setRequestMethod("POST");
line in the example in my earlier posting.
The link I worked from (also given above) specifically said the line
wasn't needed, but I guess it is. It works for me now in the emulator
in both 2.2.2 and 2.3.
