How to post multiple image files using ion library?

Question

I am using this code to upload single image file on server.

But i need to upload multiple 'n' number of files at once

Ion.with(MainActivity.this)
                .load(Constant.UPLOAD_IMG)
                .setMultipartFile("UploadForm[imageFiles]", imgFile.getName(), imgFile)
                .asJsonObject()
                .setCallback(new FutureCallback<JsonObject>() {
                    @Override
                    public void onCompleted(Exception e, JsonObject result) {
                    }
                });

I tried to get MultipartBodyBuilder separately.

 MultipartBodyBuilder body = Ion.with(MainActivity.this)
                .load(Constant.UPLOAD_IMG);

 body.setMultipartFile("UploadForm[imageFiles]", imgFile.getName(), imgFile);

Use addMultipartParts to add a list of FilePart or StringParts.
