複数の接続タイプを有効にする

Question

私は自分のアプリケーションにHTTP接続を持っていますが、現時点ではユーザーがWIFI接続に接続されている場合にのみ適用されます。特定のデバイスに接続されている場合にどのように有効にしたいのですか？デバイスにBISサービス、または通常のWAPサービスがあるとします。

これは私のコードです。

try 
    { 
     connection = (HttpConnection) Connector.open(url+ ";interface=wifi"); 
     is = connection.openInputStream(); 
     try 
     { 
      SAXParser parser = SAXParserFactory.newInstance().newSAXParser(); 
      parser.parse(is, rssHandler); 
     } 
     catch (ParserConfigurationException e) 
     { 
      e.printStackTrace(); 
     } 
     catch (SAXException e) 
     { 
      e.printStackTrace(); 
     } 
     catch (IOException e) 
     { 
      e.printStackTrace(); 
     } 
    } 

    catch (IOException e) 
    { 
     e.printStackTrace(); 
     Dialog.inform("Bad URL"); 
    }

だから、基本的に私がする必要があるすべては、上記の方法で私のhttp接続文字列を置換することである接続文字列に
