我正在尝试从AccountManager获取Twitter帐户的OAuth令牌，并使用它来关注一个Twitter账号，使用的是Twitter4j。但我得到了“未发现身份验证挑战”的TwitterException错误。
以下是获取令牌并关注用户的代码：
请指出我在这里做错了什么。
以下是获取令牌并关注用户的代码：
try{
AccountManager accountManager = AccountManager.get(getActivity());
Account twitterAccount = accountManager.getAccountsByType(AccountType.TWITTER.getType())[0];
AccountManagerFuture<Bundle> tokenFuture = accountManager.getAuthToken(twitterAccount, "com.twitter.android.oauth.token", null, true, new AccountManagerCallback<Bundle>() {
public void run(AccountManagerFuture<Bundle> result) {
Bundle bundle;
try {
bundle = result.getResult();
Intent intent = (Intent) bundle.get(AccountManager.KEY_INTENT);
if (intent != null) {
// User input required
getActivity().startActivity(intent);
} else {
String token = bundle.getString(AccountManager.KEY_AUTHTOKEN);
Log.i(TAG, "Token:" + token);
userToken = token;
}
} catch (Exception e) {
Log.e(TAG, "Error getting token", e);
}
}

configurationBuilder

Twitter twitter = new TwitterFactory(configurationBuilder.build()).getInstance();
User user = twitter.createFriendship(param.getUserName());
Toast.makeText(followListActivity,"Followed user @"+user.getScreenName()+" :)",Toast.LENGTH_SHORT);
} catch (TwitterException e) {
e.printStackTrace();
