ksoap2 이용하는데 http 202코드도 예외로 잡아 버리네요...

Question

public class MainActivity extends AppCompatActivity {
    LoginBackgroundTask backgroundTask;
    static String ID;
    static String PW;

            request.addProperty("user_id",params[0]);        //로그인시 전달할 아이디
            request.addProperty("pw",params[1]);             //로그인시 전달할 비번


            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER12);

            try {

                result=envelope.getResponse();

            }
            catch (Exception e)
            {
               e.getStackTrace();

            }
            return result;
        }
    }
}

200번만 예외에서 제외하는데 

202번도 예외에서 제외 안시킬수 없나요
