Using HttpPost to upload file Android

Question

am I uploading this file right? Here is my code:

---

Deleted Code

it is basically just a async task that sends the file (csv) to the web server.

I am getting back status code 400 :( Anyone know what I am doing wrong?

---

Edit: Now I am getting back status code 411, but when I specify the content-length it comes back with ClientProtocolException.

Here's my code now:

UploadTask uploadtask;

    public class UploadTask extends AsyncTask<Void, byte[], Boolean> {

        HttpPost httppost;

        @Override
        protected Boolean doInBackground(Void... params) {
            Boolean result = false;
            String id = projectIDs.get((int) spinner.getSelectedItemId());

            Log.i("TAG", id);
            try {

                l(send(String.valueOf(id), "http://" + site
                        + "/restlet/position.csv?project=" + id,
                        "/csv.csv"));

            } catch (ClientProtocolException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            } catch (JSONException e) {
                e.printStackTrace();
            }

            return result;
        }

        private void entity(String id, String file) throws JSONException,
                UnsupportedEncodingException, FileNotFoundException {
            // Add your data
            File myFile = new File(Environment.getExternalStorageDirectory(),
                    file);

            FileEntity fileEntity = new FileEntity(myFile, "multipart/form-data;");
            fileEntity.setChunked(true);
            long len = fileEntity.getContentLength();
            httppost.getParams().setParameter("project", id);
            httppost.setEntity(fileEntity);

            //httppost.addHeader("Content-Length",String.valueOf(len));
            httppost.setHeader("Content-Length", String.valueOf(len));
        }

        private String send(String id, String URL, String file)
                throws ClientProtocolException, IOException, JSONException {

            l(URL);

            HttpResponse response = null;

            httppost = new HttpPost(URL);

            entity(id, file);

            response = httpclient.execute(httppost);

            Header[] head = response.getAllHeaders();

            String str = String.valueOf(response.getStatusLine()
                    .getStatusCode());

            response.getEntity().consumeContent();

            return str;
        }

    }

This code here worked for uploading a file to the web server :) After many hours of struggle I got it, had to import MultipartEntity, StringBody and FileBody from apache however

httppost = new HttpPost(URL);
MultipartEntity entity = new MultipartEntity();
entity.addPart("title", new StringBody("position.csv", Charset.forName("UTF-8")));
File myFile = new File(Environment.getExternalStorageDirectory(), file);
FileBody fileBody = new FileBody(myFile);
entity.addPart("file", fileBody);
httppost.setEntity(entity);
httppost.getParams().setParameter("project", id);
