我使用twitter4j和oauth-signpost将twitter与我的Android应用程序集成。我已经实现了部分活动，它的作用是对用户进行身份验证（或至少是它应该做的事情）。问题是，它无法找到令牌并提供此错误消息：
09-22 15:44:06.123: DEBUG/TwitterApp(363): Error getting access token
09-22 15:44:06.134: WARN/System.err(363): oauth.signpost.exception.OAuthExpectationFailedException: Request token or token secret not set in server reply. The service provider you use is probably buggy.
