FileStackMultipartUploadSample.java

public void pictureUpload(final Callback<String> resultURL) {
    String picture = Capture.capturePhoto(1024, -1);
    if(picture!=null){
        String filestack = "https://www.filestackapi.com/api/store/S3?key=MY_KEY&filename=myPicture.jpg";
        MultipartRequest request = new MultipartRequest() {
           protected void readResponse(InputStream input) throws IOException  {
              JSONParser jp = new JSONParser();
              Map<String, Object> result = jp.parseJSON(new InputStreamReader(input, "UTF-8"));
              String url = (String)result.get("url");
              if(url == null) {
                 resultURL.onError(null, null, 1, result.toString());
                 return;
              }
              resultURL.onSucess(url);
           }
        };
        request.setUrl(filestack);
        try {
            request.addData("fileUpload", picture, "image/jpeg");
            request.setFilename("fileUpload", "myPicture.jpg");
            NetworkManager.getInstance().addToQueue(request);
        } catch(IOException err) {
