我正在开发一个android应用程序来获得twitter关注者。下面的代码用于身份验证，我已经成功登录。
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)));
为了得到追随者的名单，我使用了下面的代码，但我发现了错误，并附上了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:

这段代码中有什么问题。我在Emulator中读到了一些检查时间戳的帖子。但是Emulator中的时间和日期是正确的。请提供一些帮助。提前谢谢。

我this对吧？
最佳答案
在我的项目中，我有这个代码是为了吸引追随者。
也许主要的一点与使用AsyncTask有关。
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();
