有没有一种方法可以使用Volley将多个请求发送到服务器

我正在尝试使用凌空库将加速度计x y z值发送到服务器， 但是执行了一段时间后，它显示了以下问题

  

2019-03-23 11：34：42.610 9772-9977 / com.example.acer.smarhelmetmain D / Volley：？> [4173] BasicNetwork.logSlowRequests：请求的HTTP响应= <[]> {{3} } 0x67692a02 NORMAL [lifetime = 9613]，[size = 0]，[rc = 200]，[retryCount = 0]

并使应用崩溃，并显示“请重试”错误

我使用了CountDownTimer并设置了每5秒执行一次的请求，如下所示

package com.example.acer.smarhelmetmain.service;

    @Override
    public IBinder onBind(Intent intent) {
        throw new UnsupportedOperationException("Not yet implemented");
    }

    @Override

        super.onCreate();

        sensorManager.registerListener(this,
                sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER),
                SensorManager.SENSOR_DELAY_NORMAL);
        countDownTimer = new CountDownTimer(Long.MAX_VALUE,5000) {
            @Override

        StringRequest request=new StringRequest(Request.Method.GET, c_url, new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {
                crashDetection(response);
                if(response.equals("1"))
                {
                    countDownTimer.cancel();
                }
                else
                {
                    countDownTimer.start();
                }
                Log.d("CRASHDETECTION", "onResponse: "+response);
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {

            }
        });
        requestQueue.add(request);
    }

    @Override
    public void onSensorChanged(SensorEvent event) {
        if (event.sensor.getType() == Sensor.TYPE_ACCELEROMETER) {
            getAccelerometer(event);
        }
    }
    private void getAccelerometer(SensorEvent event) {
        float[] values = event.values;
        // Movement
        final float x = values[0];
        final float y = values[1];
        final float z = values[2];
        CountDownTimer countDownTimer=new CountDownTimer(Long.MAX_VALUE,5000) {
            @Override
            public void onTick(long millisUntilFinished) {

                insertToDB(x,y,z);
            }

            @Override
            public void onFinish() {
                start();
            }
        }.start();
    }

    private void crashDetection(String status) {
        if(status.equals("1"))
        {
            startActivity(new Intent(getApplicationContext(),AlertActivity.class).addFlags(Intent.FLAG_ACTIVITY_NEW_TASK));
        }
    }

    private void insertToDB(float x, float y, float z) {

        final HashMap<String,String> param = new HashMap<>();
        param.put("x",String.valueOf(x));
        param.put("y",String.valueOf(y));
        param.put("z",String.valueOf(z));
        param.put("imei",imei);
        RequestQueue requestQueue=Volley.newRequestQueue(this);
        StringRequest req=new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {

            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {

            }
        }){
            @Override
            protected Map<String, String> getParams() throws AuthFailureError {

                return param;

            }
        };

        requestQueue.add(req);
    }

    @Override
    public void onAccuracyChanged(Sensor sensor, int accuracy) {

    }
}

我希望每5秒钟将数据发送到服务器，而不会出现任何问题。

这是我在运行代码时遇到的错误，应用程序崩溃了
