Question

从Android应用程序中，我使用Volley库来处理POST请求。这些请求用于将数据发送到放置我的服务器和数据库的URL。我使用以下代码，在4分钟的限制内完美运行。然后屏幕停止响应，应用程序停止运行。有人可以帮我解决这个问题吗？

    requestQueue = Volley.newRequestQueue(getApplicationContext());

    String insertUrl = "http://192.168.1.16/html/emoncms/input/post.json?node=bdd&json={power:"
            + mHrmValue +"}&apikey=c8e78867509aa883a0fd23e323e966f1";
    StringRequest request = new StringRequest(Request.Method.POST,
            insertUrl, new Response.Listener<String>() {

        @Override
        public void onResponse(String response) {
            System.out.println(response.toString());
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            Toast.makeText(HRSActivity.this, "Error: " + error,
                    Toast.LENGTH_SHORT).show();
        }
    });
    requestQueue.add(request);

这是logcat：

Answer 1

logcat非常有用，因为它显示了内存分配问题。我通过在onCreate（）方法中移动requestQueue来解决问题。它节省了内存，因为requestQueue只被调用一次。它现在正常工作，没有时间限制。非常感谢！
