Hi,
Sorry to bump this again, but I've looked over the examples again, and
I still cannot see where I am going wrong! I'm still getting an null
body back when i do:
OAuthMessage result = accessor.newRequestMessage(OAuthMessage.GET,
"http://brightkite.com/places/search.json";,
OAuth.newList("q", myLocation.getLatitude() + "," +
myLocation.getLongitude()));
String result_message = result.readBodyAsString();
Any help will be much appreciated, as my app really depends on this!
