在不使用gluon connect的情况下连接到Gluon mobile中的REST api，但是其他库（例如Unirest）

Question

我一直在尝试从gluon mobile连接到REST端点，但是当应用程序部署在移动本身上时，我面临挑战。每次我尝试按按钮进行连接时，它就会崩溃（应用程序停止工作）。但是，在台式机上进行测试时，一切工作正常。这是代码

button.setOnAction(e -> {

        JSONObject reqJson = new JSONObject();
        reqJson.put("username", username.getText());
        reqJson.put("password", password.getText());

        Future<HttpResponse<JsonNode>> future = Unirest.post("http://xxx.xxx.xx:8087/business/login")
                .header("accept", "application/json")
                .body(reqJson.toJSONString())
                .asJsonAsync(new Callback<JsonNode>() {

                    public void failed(UnirestException e) {
                        System.out.println("The request has failed");
                    }

                    public void completed(HttpResponse<JsonNode> response) {
                        System.out.println("successfull");
                        System.out.println("...");
                        MobileApplication.getInstance().switchView("DASHBOARD_VIEW");
                    }

                    public void cancelled() {
                        System.out.println("The request has been cancelled");
                    }

                });

    });

我的build.gradle看起来像这样
