Multiple image uploading using multipart retrofit or volley

Question

Hi Can any one Please help me out in uploading multiple images selected from gallery, parameter is 'images' as array list I have tried with this but no response can any one help me out..

This is my request body :

  MediaType mediaType = MediaType.parse("multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW");
    MultipartBody.Builder mRequestBody = new MultipartBody.Builder()
            .setType(MultipartBody.FORM);
    if (Imagepaths.size() > 0) {
        for(String path:Imagepaths) {
            File file = new File(path);
            mediaType = path.endsWith("png") ?
                    MediaType.parse("image/png") : MediaType.parse("image/jpeg");
            RequestBody imageBody = RequestBody.create(mediaType, file);
            mRequestBody.addFormDataPart("images", file.getName(), imageBody);
        }
    }

    RequestBody rb = mRequestBody.build();

This is the retrofit call :

 @Multipart
@POST("upload_images/")
Call<ResponseBody> retrofitImageUpload(@Header("Authorization") String auth,
                                       @Header("Content-Type") String contentType,
                                       @Part("images") RequestBody req);
