我正在尝试使用抄写员进行Twitter授权。当我尝试
requestToken = service.getRequestToken()
我收到以下错误

我尝试了以下帖子中提到的答案，但没有任何效果
scribe + twitter > Cannot get String from a null object
每当我尝试包括TwitterApi.SSL.class或TwitterApi.Authenticate.class时，都会出现“无法解析为类型”错误。
有人遇到过这个问题吗？
最佳答案
使用.provider（TwitterApi.SSL.class）代替.provider（TwitterApi.class）。
它应该工作。
