Не удалось загрузить файл с использованием данных multipart/form

Question

У меня возникла проблема с загрузкой файла с использованием данных многостраничной формы. Я дал скриншот ARC с api и моим настоящим кодом. Любая помощь будет оценена по достоинству.

public class MultiPortRequest<T> extends Request<T> { 

    private static final String FILE_PART_NAME = "file"; 

    private MultipartEntityBuilder mBuilder = MultipartEntityBuilder.create(); 
    private final Response.Listener<String> mListener; 
    private final File mImageFile; 
    protected Map<String, String> headers; 

    public MultiPortRequest(String url,Response.Listener<String> listener, 
           ErrorListener errorListener, 

           File imageFile) 
    { 
     super(Method.POST, url, errorListener); 

     mListener = listener; 
     mImageFile = imageFile; 

     buildMultipartEntity(); 
    } 

    @Override 
    public Map<String, String> getHeaders() throws AuthFailureError { 
     Map<String, String> headers = super.getHeaders(); 

     if (headers == null 
       || headers.equals(Collections.emptyMap())) { 
      headers = new HashMap<String, String>(); 
     } 

     headers.put("Identity", "rHTYsg8vZ/KWTaGOsy0eMNhngJMiZiK60pd9jAUQ+fI="); 

     return headers; 
    } 

    private void buildMultipartEntity() 
    { 
     mBuilder.addBinaryBody(FILE_PART_NAME, mImageFile, ContentType.create("multipart/form-data"), 
       mImageFile.getName()); 

     mBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE); 
     mBuilder.setLaxMode().setBoundary("xx").setCharset(Charset.forName("UTF-8")); 
    } 

    @Override 
    public String getBodyContentType() 
    { 
     String contentTypeHeader = mBuilder.build().getContentType().getValue(); 
     return contentTypeHeader; 
    } 

    @Override 
    public byte[] getBody() throws AuthFailureError 
    { 
     ByteArrayOutputStream bos = new ByteArrayOutputStream(); 
     try 
     { 
      mBuilder.build().writeTo(bos); 
     } 
     catch (IOException e) 
     { 
      VolleyLog.e("IOException writing to ByteArrayOutputStream bos, building the multipart request."); 
     } 

     return bos.toByteArray(); 
    } 

    @Override 
    protected Response<T> parseNetworkResponse(NetworkResponse response) 
    { 
     try { 
      String result = null; 
      result = new String(response.data, HttpHeaderParser.parseCharset(response.headers)); 
      return (Response<T>) Response.success(new JSONObject(result), HttpHeaderParser.parseCacheHeaders(response)); 
     } catch (UnsupportedEncodingException e) { 
      return Response.error(new ParseError(e)); 
     } catch (JSONException je) { 
      return Response.error(new ParseError(je)); 
     } 
    } 

    @Override 
    protected void deliverResponse(T response) 
    { 
     mListener.onResponse(response.toString()); 
     Log.v("yes", String.valueOf(mListener)); 
    } 
}
