我正在将 Twitter oAuth 系统用于我的应用程序，特别是遵循本教程： http: //www.markhneedham.com/blog/2012/01/02/learning-android-authenticating-with-twitter-using-oauth /。我似乎收到了基于我的回调 URL 的错误，我只是无法在任何地方找到有关如何正确执行此操作的解决方案或正确信息。我的应用程序的名称是啁啾，生病发布代码和错误，任何帮助将不胜感激！
注意：当我尝试通过 twitter 开发人员在我的应用程序页面上设置它们时，很多教程都有 CALLBACKURL 的随机 Twitter URL，例如“app://twitter”，它们是“无效 URL”。目前，我在我的应用程序的开发人员页面和代码中都将 CALLBACKURL 设置为http://crownseal.ca（随机站点）。
