org.apache.http.conn.HttpHostConnectException: подключение к http://localhost отклонено в android

Я делаю приложение, которое загружает изображения на сервер и обновляет свою базу данных на сервер в Android при его выполнении, оно показывает ошибку

Connection to http://localhost refused 

и многие другие ошибки, я исследовал эту проблему и нашел вместо предоставления URL-подключения

http://localhost/... provide the link as http://10.0.2.2/... 

и я так и сделал, но проблема такая же, больше ошибок здесь:

код для загрузки файла:

public int uploadFile(ArrayList<String> sourceFileUri, String info, String latitude, String longitude, String id) throws IOException {
        try {
            HttpClient httpClient = new DefaultHttpClient();
            HttpContext localContext = new BasicHttpContext();
            HttpPost httpPost = new HttpPost("http://10.0.2.2/deliverysystem/order/add");

            MultipartEntity entity = new MultipartEntity(
                    HttpMultipartMode.BROWSER_COMPATIBLE);

            entity.addPart("returnformat", new StringBody("json"));
            System.out.println(sourceFileUri.size());
            for(int i=0;i<sourceFileUri.size();i++){
                String sourceFile = sourceFileUri.get(i);
                entity.addPart("uploaded_file"+(i+1), new FileBody(new File(sourceFile)));
            }

            entity.addPart("fld_delivery_id", new StringBody(id));
            entity.addPart("fld_delivery_location", new StringBody(info));
            entity.addPart("fld_latitude", new StringBody(latitude));
            entity.addPart("fld_longitude", new StringBody(longitude));
            httpPost.setEntity(entity);
            HttpResponse response = httpClient.execute(httpPost, localContext);
            BufferedReader reader = new BufferedReader(
                    new InputStreamReader(
                            response.getEntity().getContent(), "UTF-8"));

            String sResponse = reader.readLine();
            return 1;
        } catch (Exception e) {
            if (dialog.isShowing())
                dialog.dismiss();

            Log.e(e.getClass().getName(), e.getMessage(), e);
            return 1;
        }

       }

во время отладки код достигает:

httpPost.setEntity(entity);

и он показывает исключение после этой строки, т.е. в этом утверждении:

HttpResponse response = httpClient.execute(httpPost, localContext);

Может ли кто-нибудь помочь мне в этом?
