我正在使用應用程序來使用Twitter4j庫在Twitter中授權用戶。我想加入一個功能,我的移動應用程序打開。它有一個登錄按鈕,點擊哪個Twitter登錄對話框出現,並讓你輸入登錄信息。登錄完成後,將打開另一個屏幕。Android for Android的oAuth中的錯誤

但是在運行此應用程序,它給了我錯誤的logcat:
11-18 10:36:27.727: E/in Main.OAuthLogin(282): 401:Authentication credentials (https://dev.twitter.com/docs/auth) were missing or incorrect. Ensure that you have set valid conumer key/secret, access token/secret, and the system clock in in sync.

我相信我還沒有設置回調URL,但我確實在我的應用程序,以及對https://dev.twitter.com/pages/welcome-anywhere 。
