Hello Its to late for answering this question but this will be helpful who are still finding ans with Android-annotation

You can check your image progress by little bit manipulation of code and here is what i have created my

Custom converter Class:-

public class CustomConverter extends FormHttpMessageConverter {

OnProgressListener mOnProgressListener;

public CustomConverter() {
    super();

    List<HttpMessageConverter<?>> partConverters = new ArrayList<HttpMessageConverter<?>>();
    partConverters.add(new ByteArrayHttpMessageConverter());
    StringHttpMessageConverter stringHttpMessageConverter = new StringHttpMessageConverter();
    stringHttpMessageConverter.setWriteAcceptCharset(false);
    partConverters.add(stringHttpMessageConverter);
    partConverters.add(new ProgressResourceHttpMessageConverter());
    setPartConverters(partConverters);
}

// public ProgressFormHttpMessageConverter setOnProgressListener(OnProgressListener listener) { // mOnProgressListener = listener; // return this; // }

class ProgressResourceHttpMessageConverter extends ResourceHttpMessageConverter {

    @Override
    protected void writeInternal(Resource resource, HttpOutputMessage outputMessage) throws IOException, HttpMessageNotWritableException {
        InputStream inputStream = resource.getInputStream();
        OutputStream outputStream = outputMessage.getBody();

        byte[] buffer = new byte[2048];
        long contentLength = resource.contentLength();
        int byteCount = 0;
        int bytesRead = -1;
        Log.d("<3 <3 <3", "called");
        while ((bytesRead = inputStream.read(buffer)) != -1) {
            outputStream.write(buffer, 0, bytesRead);
            byteCount += bytesRead;
            Log.d("<3 <3 <3 ** ", "progress" + String.valueOf((byteCount * 100) / contentLength));
            if(mOnProgressListener != null) {
                mOnProgressListener.onProgress(resource, byteCount, (int) contentLength);
            }
        }
        outputStream.flush();
    }
}

public interface OnProgressListener {
    void onProgress(Resource resource, int downloaded, int downloadSize);
}
}

--> you can check your progress with log :)

Code Usage

-> Your rest class will be as follow:-

@Rest(rootUrl = CommonUtils.BASE_URL, converters = {ByteArrayHttpMessageConverter.class,
    CustomConverter.class, StringHttpMessageConverter.class})

public interface CustomRest extends RestClientErrorHandling {


@Post(pUrlSignUp)
String _SignUp(MultiValueMap<String, Object> multiValueMap);
