мое приложение отлично работает с Wi-Fi, но дает исключение на 2g, 3g

Question

Это происходит, главным образом, когда я загружаю изображения на сервер. Я использую ftp-uploder для загрузки изображений. Я попробовал его с Wi-Fi, работая абсолютно нормально. Я новичок в этом Senario .pls помочь .....

Мой класс uploder Файл:

public void uploadFile(Context context, File fileName) { 
     FTPClient client = new FTPClient(); 

     try { 
      flag = false; 
      if (!client.isConnected()) { 
      client.setSecurity(FTPClient.SECURITY_FTPES); 
      // client.setSecurity(FTPClient.SECURITY_FTP); 
       try { 
        client.connect(FTP_HOST, 21); 
        client.setType(FTPClient.TYPE_BINARY); 
        SSLContext sc = SSLContext.getInstance("SSL"); 
        sc.init(null, trustAllCerts, new java.security.SecureRandom()); 
        client.setSSLSocketFactory(sc.getSocketFactory()); 
        client.login(FTP_USER, FTP_PASS); 

       } catch (Exception e) { 
        e.printStackTrace(); 
       } 
       client.setType(FTPClient.TYPE_BINARY); 

       client.changeDirectory(UPLOAD_PATH); 
       client.upload(fileName); 
       flag = true; 
      } 
     } catch (Exception e) { 
      e.printStackTrace(); 
      try { 
       client.disconnect(true); 
      } catch (Exception e2) { 
       e2.printStackTrace(); 
      } 
      flag = false; 
     } 
    }

Ваше соединение WiFi имеет хорошую скорость, но 3g/2g этого не имеет. Таким образом, это время. увеличить время ожидания подключения

HttpParams httpParameters = new BasicHttpParams(); 
// Set the timeout in milliseconds until a connection is established. 
// The default value is zero, that means the timeout is not used. 
int timeoutConnection = 3000; 
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection); 
// Set the default socket timeout (SO_TIMEOUT) 
// in milliseconds which is the timeout for waiting for data. 
int timeoutSocket = 5000; 
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket); 

HttpClient httpClient = new DefaultHttpClient(httpParameters); 
HttpPost post = new HttpPost(urls[0]); 

post.setEntity(new UrlEncodedFormEntity(arr)); 
HttpResponse response = httpClient.execute(post);
