static void writeData(String fileurl, boolean append, String path, 
     String filename, Activity mContext) throws CustomException

     length = conn.getContentLength(); 
     System.out.println("total length.." + length); 

     int interval = (int)length/100; 
     if (length > 0) { 
      InputStream is = conn.getInputStream(); 
      BufferedInputStream bis = new BufferedInputStream(is); 
      baf = new ByteArrayBuffer(1000); 
      int current = 0;

        baf.append((byte) current); 
        mBufferError=false;

     path = path + "/" + filename; 
     boolean appendData = append;

      File file = new File(path);

       return; 
      } catch (Exception err) { 
       Log.e("SAX", err.toString()); 
      } 
     } 
     if (!appendData && !exist) { 
     } else if (appendData && !exist) { 

     } else { 
      try { 
       foutstream = new FileOutputStream(file, appendData); 
       foutstream.write(baf.toByteArray()); 
       foutstream.close(); 
      } catch (Exception e) { 
       System.out.println("error in closing! " + e); 
       e.printStackTrace(); 
      } 
     } 
    } 
    }catch (Exception e) { 
     // TODO: handle exception 
     throw new CustomException("@@@ I/O problem ", "I/O Error"); 
    } 
} 

可能這個服務，其中fileurl =您的網址和路徑=本地路徑來存儲
