如何将大视频文件发送到android中的服务器

Question

您好我正在尝试使用Volley库将大型视频文件上传到服务器但是当我向服务器请求大视频文件时，它需要花费太多时间并且视频无法上传存在服务器端限制 4MB

我如何解决这个问题，请帮我一些

我的代码：

  RequestQueue queue = Volley.newRequestQueue(context.getApplicationContext());
                final String url = Constants.SERVER_URL + serverUrl;

                MultipartAPI multipartAPI = new MultipartAPI(url, params, authenticationHeaders,fileType,fileMap, reqType,
                        new Response.ErrorListener() {

                            @Override
                            public void onErrorResponse(VolleyErrorvolleyError) {
                                // progressDialog.dismiss();
                                if (volleyError != null) {

                                }
                            }
                        }, new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        System.out.println("------->" + response);

                    }
                });

                int socketTimeout = 450000;
                RetryPolicy policy = new DefaultRetryPolicy(socketTimeout,
                        DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
                        DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);
                multipartAPI.setRetryPolicy(policy);
                queue.add(multipartAPI);

        // updating progress bar value
        progressBar.setProgress(progress[0]);

        // updating percentage value
        txtPercentage.setText(String.valueOf(progress[0]) + "%");
    }

    @Override

                        }
                    });

            File sourceFile = new File(" Your File Path");

            // Adding file data to http body

            HttpEntity r_entity = response.getEntity();

            int statusCode = response.getStatusLine().getStatusCode();
            if (statusCode == 200) {

            } else {
                responseString = "Error occurred! Http Status Code: "
                        + statusCode;
