Spring for Android, file upload progress

I'm using Spring for Android as a REST template for remote calls in Android app.

Currently working on uploading images to the server.

I came up with something like that:

public Picture uploadPicture(String accessToken, String fileToUpload) throws RestClientException {
    RestTemplate rest = new RestTemplate();
    FormHttpMessageConverter formConverter = new FormHttpMessageConverter();
    formConverter.setCharset(Charset.forName("UTF8"));
    CustomGsonHttpMessageConverter jsonConverter = new CustomGsonHttpMessageConverter();
    rest.getMessageConverters().add(formConverter);
    rest.getMessageConverters().add(jsonConverter);
    String uploadUri = AppConfig.ROOT_URL.concat(AppConfig.ADD_PHOTO);

    HashMap<String, Object> urlVariables = new HashMap<String, Object>();
    urlVariables.put("accessToken", accessToken);

    HttpHeaders httpHeaders = new HttpHeaders();
    httpHeaders.setAccept(Collections.singletonList(MediaType.parseMediaType("application/json")));

    MultiValueMap<String, Object> parts = new LinkedMultiValueMap<String, Object>();
    parts.add("picture", new FileSystemResource(fileToUpload));
    Picture response = rest.postForObject(uploadUri, parts, Picture.class, urlVariables);
    return response;
}

which works OK, but now I'd like to get progress updates from it.

Does anyone know if it's possible and how to do that?

Thanks in advance :)
