Question

我正在开发Android应用以获取Twitter粉丝。以下代码用于身份验证，我已成功登录。

consumer = new CommonsHttpOAuthConsumer(
                        key,
                        secret);
                CommonsHttpOAuthProvider provider = new CommonsHttpOAuthProvider(
                        "http://twitter.com/oauth/request_token",
                        "http://twitter.com/oauth/access_token",
                        "http://twitter.com/oauth/authorize");

                String authUrl = provider.retrieveRequestToken(consumer,
                        TWITTER_CALLBACK_URL);
                Log.e("Twittwer ", "Please authorize this app!");

                startActivity(new Intent(Intent.ACTION_VIEW,
                        Uri.parse(authUrl)));

为了获得关注者列表，我使用了下面的代码，但是我收到错误并且附加了logcat

AccessToken accessToken = new AccessToken(consumer.getToken(),
                    consumer.getTokenSecret());
            ConfigurationBuilder builder = new ConfigurationBuilder();
            builder.setOAuthConsumerKey(key);
            builder.setOAuthConsumerSecret(secret);
            Configuration conf = builder.build();
            twitter = new TwitterFactory(conf).getInstance();
            twitter.setOAuthAccessToken(accessToken);
            IDs followersId = twitter.getFollowersIDs(twitter.getId());
            do {
                for (long i : followersId.getIDs()) {



                    System.out.println("follower ID #" + i);
                    System.out.println(twitter.showUser(i).getName());
                    System.out.println(twitter.showUser(i)
                            .getProfileImageURL());
                    System.out.println(twitter.showUser(i).getURL());

                }
            } while (followersId.hasNext());
        } catch (TwitterException e) {
            System.out.println("e........"+e.getMessage());
            e.printStackTrace();

        }

logcat的：

这段代码有什么问题。我在一些帖子中读到了检查模拟器中的时间戳。但是模拟器中的时间和日期是正确的。请给我一些帮助。谢谢提前..

[编辑] 我this对吗？

在我的项目中，我有这个代码来获取关注者。也许主要观点与使用AsyncTask。

    if (twitter == null){
        ConfigurationBuilder builder = new ConfigurationBuilder();
        Configuration conf = builder
        .setOAuthConsumerKey(CONSUMER_KEY)
        .setOAuthConsumerSecret(CONSUMER_SECRET)
        .setOAuthAccessToken(oAuthAccessToken)
        .setOAuthAccessTokenSecret(oAuthAccessTokenSecret)
        .build();
        twitter = new TwitterFactory(conf).getInstance();
    }


    new AsyncTask<Void, Void, Void>() {
        @Override
        protected Void doInBackground(Void... params) {
            long lCursor = -1;
            AccessToken accessToken = new AccessToken(oAuthAccessToken, oAuthAccessTokenSecret);
            long userId = accessToken.getUserId();
            try {
                IDs followersIDs = twitter.getFollowersIDs(userId, lCursor);
                do {
                    for (long i : friendsIDs.getIDs()){
                        Log.d("follower ID #", String.valueOf(i));
                    }
                }while(followersIDs.hasNext());
            } catch (TwitterException e) {
                Log.i("fetchFollowers", e.getErrorMessage());
            }
            return null;
        }

        @Override
        protected void onPostExecute(Void param) {
        }

    }.execute();
