在 android 中使用路标请求访问令牌时收到 401

这是我的代码，我不断收到异常“授权失败（服务器回复 401）。如果消费者密钥不正确或签名不匹配，则可能会发生这种情况。”在这一行“provider.retrieveAccessToken(consumer, verifier);”。我已经三次检查了我的消费者密钥和秘密，我的 Twitter 应用程序被设置为浏览器并尝试设置provider.setOAuth10a(true)，我已经为此苦苦挣扎了 2 天！我正在使用路标 1.2.1.1 (core & commonshttp4)，如果有人可以提供帮助！请我绝望

刚刚找到了一个可能的解决方案：您需要在 Twitter 应用程序帐户上设置回调 URL。
