Androidファイルアップロード

Question

httpを使用してサーバーにファイルをアップロードします。 System.out.println（（（HttpURLConnectionの）URLConnectionの）.getResponseMessage（））に

 try { 
     URL url = new URL(dst); 
      File file = new File(src); 
      urlconnection = url.openConnection(); 
      urlconnection.setDoOutput(true); 
      urlconnection.setDoInput(true); 

      if (urlconnection instanceof HttpURLConnection) { 
      try { 
      ((HttpURLConnection)urlconnection).setRequestMethod("PUT"); 
      ((HttpURLConnection)urlconnection).setRequestProperty("Content-type", "text/html"); 
      ((HttpURLConnection)urlconnection).connect(); 


      } catch (ProtocolException e) { 

      e.printStackTrace(); 
      } 
      } 


      BufferedOutputStream bos = new BufferedOutputStream(urlconnection 
      .getOutputStream()); 
      BufferedInputStream bis = new BufferedInputStream(new FileInputStream(
      file)); 
      int i; 
      // read byte by byte until end of stream 
      while ((i = bis.read()) >0) { 
      bos.write(i); 
      } 
      System.out.println(((HttpURLConnection)urlconnection).getResponseMessage()); 

      } 
      catch(Exception e1) 
      { 
      e1.printStackTrace(); 
      } 
      try { 

      InputStream inputStream; 
      int responseCode=((HttpURLConnection)urlconnection).getResponseCode(); 
      if ((responseCode>= 200) &&(responseCode<=202)) { 
      inputStream = ((HttpURLConnection)urlconnection).getInputStream(); 
      int j; 
      while ((j = inputStream.read()) >0) { 
      System.out.println(j); 
      } 

      } else { 
      inputStream = ((HttpURLConnection)urlconnection).getErrorStream(); 
      } 
      ((HttpURLConnection)urlconnection).disconnect(); 

      } catch (IOException e) { 

      e.printStackTrace(); 
      }
