Send Images as Multipart with Volley request

Question

I want to send multipart request so that image can be sent to the server through volley. I want to send two other paramters along with image list but i don't know how to pass images list in volley request params. My code for getting image from gallery and storing their paths in array list is:

List<String> imagePathList = imageFilePaths;
        List<MultipartBody.Part> partMap = new ArrayList<>();
        for (int i = 0; i < imagePathList.size(); i++) {
            Uri fileUri = Uri.parse(imagePathList.get(i));
            RequestBody requestFile = RequestBody.create(
                    MediaType.parse(getMimeTypee(FileUtils.getFile(getContext(), fileUri).getAbsolutePath())),
                    FileUtils.getFile(getContext(), fileUri)
            );

           MultipartBody.Part body = MultipartBody.Part.createFormData("court_image[" + i + "]", FileUtils.getFile(getContext(), fileUri).getName(), requestFile);
           partMap.add(body);
        }

where imageFilePaths is an array list. The server will receive images like court_image[0], court_image[1] and so on, depends on how many image paths i have in arraylist.

The volley request is here:

 RequestQueue queue = Volley.newRequestQueue(getContext());
        StringRequest postRequest = new StringRequest(Request.Method.POST, url1,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        Toast.makeText(mBaseAppCompatActivity, "Success", Toast.LENGTH_SHORT).show();
                   }
                },
                new Response.ErrorListener() {

                    @Override
                    public void onErrorResponse(VolleyError error) {

                    }
                }
        ) {

            @Override
            public Map<String, String> getHeaders() throws AuthFailureError {
                Map<String, String> params = new HashMap<String, String>();
                String token = getToken();
                params.put("Authorization", "Bearer " + token);
                params.put("Content-Type", "multipart/form-data");
                return params;
            }

            @Override
            protected Map<String, String> getParams() {
                Map<String, String> params = new HashMap<String, String>();
                params.put("terms", "true");
                params.put("phone", "phoneNo");
                return params;
            }

        };
        queue.add(postRequest);

Now the thing is as I am new to the multi-part thing, with the help I am able to get the image from gallery and storing their path in ArrayList but I don't know how to pass the multipart data in this volley request. Please Help
