target:  Parse a server response into a JSON Object. This is a basic implementation using org.json.JSONObject representation. More sophisticated applications may wish to do their own parsing. The parsed JSON is checked for a variety of error fields and a FacebookException is thrown if an error condition is set, populated with the error message and error type or code if available.
