使用访问令牌和令牌密码在android应用程序中发布到tumblr

我正在尝试使用访问令牌在tumblr上发布文本。这些访问令牌是我从web应用程序的web服务获得的。请帮忙

这是我的代码，它在执行身份验证错误后显示此消息：无法响应任何这些挑战

                String token = list.get(i).getAccess_token();
                String tokenSecret = list.get(i).getAccess_token_secret();

                System.out.println("token :"+token);
                System.out.println("token secret :"+tokenSecret);


                HttpPost hpost = new HttpPost("http://api.tumblr.com/v2/blog/" +list.get(i).getUser_Name()+ ".tumblr.com/post");

                List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
                nameValuePairs.add(new BasicNameValuePair("type", "text"));
                nameValuePairs.add(new BasicNameValuePair("title", title));
                nameValuePairs.add(new BasicNameValuePair("body", body));

                CommonsHttpOAuthConsumer consumer = new CommonsHttpOAuthConsumer(Tumblr.TUMBLR_CONSUMERKEY, Tumblr.TUMBLR_SECRETKEY);
                consumer.setTokenWithSecret(token, tokenSecret);

                try {
                    consumer.sign(hpost);
                } catch (OAuthMessageSignerException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (OAuthExpectationFailedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (OAuthCommunicationException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

                DefaultHttpClient client = new DefaultHttpClient();
                HttpResponse resp = null;

                try {
                    resp = client.execute(hpost);
                } catch (ClientProtocolException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

            }

以下代码适用于我：

        public PostToTumblr(TumblrUser user) {
            this.user= user;
            progressDlg = new ProgressDialog(mContext);
            progressDlg.setMessage("Posting Message ");

            this.userName = user.getName();
            oAuthConsumer = new CommonsHttpOAuthConsumer(Const.CONSUMER_KEY,
