Header into url link Android

I have method on the Spring server which requires user token to allow downloading the resource. The resource is sent by url in TextView. When I click the url, the browser opens, but obviously without any header added. How can I add a header with a token to my request? Or how can I handle this web browser event to call my own function with the header added?

I have done a lot of research but couln't find the answer.

Here is my /download method at Spring server

@RequestMapping(value = "/download/{name:.+}", method = RequestMethod.GET)
    public HttpEntity<?> downloadFile (@RequestHeader("token") String token,
                                       @PathVariable("name") String name,
                                       final HttpServletRequest request, final HttpServletResponse response) throws IOException {

        if (tokenRepository.findByKeyVal(token) == null) {
            return null;

        }

        User userFrom = userRepository.findByToken(token);
        if(name.contains("_"+ userFrom.getId() +"_")){

         //  files names are saved in timestap + _user1+_user2 format//
            Resource resource;
            Path path = Paths.get(uploadDir + name);
            try {
                resource = new UrlResource(path.toUri());
            } catch (MalformedURLException e) {
                e.printStackTrace();
                return null;
            }

            // Try to determine file's content type
            String contentType = null;
            try {
                contentType = request.getServletContext().getMimeType(resource.getFile().getAbsolutePath());
            } catch (IOException ex) {
                System.out.println("Could not determine file type.");
            }

            // Fallback to the default content type if type could not be determined
            if (contentType == null) {
                contentType = "application/octet-stream";
            }

            return ResponseEntity.ok().contentType(MediaType.parseMediaType(contentType))
                    .header(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=\"" + resource.getFilename() + "\"")
                    .body(resource);
        }
        else return new ResponseEntity<String>("Unauthorized", HttpStatus.UNAUTHORIZED);

    }
