When I query a feature layer I have been getting a sample error on some of the fields. I did not have this problem with the old java SDK.
Originally, I tested this class by getting data from an AGOL secure service and ran into problems with retrieving half of the fields. So to simplify the test I used esri's sample service and got the same results. Below is a simple class that prints out the values in a row. However when I try to get the <state_abbr> data the program fails.
Esri, please help me on this.
