使用okhttp3出现超时异常

[lyz998]

主要框架

这是btn_finishDM按钮的点击事件

findViewById(R.id.btn_finishDM).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                cancelScanBule();
                List<Sign> signList = new ArrayList<>();
                /*已到学生记录*/
                // .........do something
                /*未到学生列表*/
                //.........do something
                if (!signList.isEmpty()){
                    submitStuList(signList);
                }else {
                    sendMessage(3,"没有学生，点名异常");
                }

            }
        });

这是提交的线程

private void submitStuList(List<Sign> mSignStuList) {
        new Thread(new Runnable() {
            @Override
            public void run() {
                HttpConnection.sendOkHttpRequest(url, mSignStuList, mSubminCallback);//url自定义的
            }
        }).start();
    }

这是回调方法

mSubminCallback = new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
                Log.i(TAG,e.getMessage()); /**这里有时就会报错**/
                sendMessage(3, "点名失败");
            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
                String responseData = response.body().string();
                Log.i(TAG, "响应信息： " + responseData);
                if (responseData.equals("true")) {
                    sendMessage(3, "点名成功");
                    finish();
                }
            }
        };

这是用okhttp3封装的方法

public static void sendOkHttpRequest(String address, List<Sign> signList, Callback callback){
        OkHttpClient client = new OkHttpClient();

        String params = new Gson().toJson(signList);
        Log.i("提交学生签到情况",params);
        MediaType JSON = MediaType.parse("application/json; charset=utf-8");
        RequestBody requestBody = RequestBody.create(JSON, params);
        Request request = new Request.Builder().url(address).post(requestBody).build();
        client.newCall(request).enqueue(callback);
    }

报错原因也很奇怪，当我点击蓝牙扫描按钮，再点击btn_finishDM按钮时，有时就会出现超时，servlet接收不到
但是，如果我直接点击btn_finishDM按钮，就没有出现超时

可以测试一下是不是因为蓝牙扫描导致断网了
