CamFind java.lang.NoClassDefFoundError:org.apache.http.client.config.RequestConfig

我正在尝试将CamFind添加到我的android应用程序中。这是我请求图像的代码

来自活动的代码

try {
            HttpResponse<JsonNode> response = Unirest.post("https://camfind.p.mashape.com/image_requests")
                    .header("X-Mashape-Key", "5Bjknd4AL0mshPTXoeE0oZGyTuRFp1zzpYEjsnWlO4mJju8hjV")
                    .header("Content-Type", "application/x-www-form-urlencoded")
                    .field("focus[x]", "480")
                    .field("focus[y]", "640")
                    .field("image_request[altitude]", "27.912109375")
                    .field("image_request[language]", "en")
                    .field("image_request[latitude]", "35.8714220766008")
                    .field("image_request[locale]", "en_US")
                    .field("image_request[longitude]", "14.3583203002251")
                    .field("image_request[remote_image_url]", "http://upload.wikimedia.org/wikipedia/en/2/2d/Mashape_logo.png")
                    .asJson();
        } catch (UnirestException e) {
            e.printStackTrace();
        }

我的日志中出现以下错误

第32行是

.asJson（）
你能发布MyActivity类的第32行吗？@hrskrs我已经编辑了我的问题，不管怎样，它是
