android - 登录推特总是去回调失败方法

Question

没有显示错误，但是当单击按钮时，它总是会回调失败方法。互联网处于 Activity 状态并且 key 有效。我使用调试器看到以下结果:-

Answer 1

当我的设备上没有安装 Twitter 应用程序时，我遇到了同样的错误。

Desktop applications only support the oauth_callback value 'oob' /oauth/request_token

但是当 Twitter 应用程序安装在设备上时，Twitter 登录工作正常。

如果设备上未安装 Twitter 应用程序，要使 Twitter 登录正常工作，请对您的应用程序进行以下更改:

https://apps.twitter.com/app/13917465/permissions

转到应用程序中的“权限”选项卡，将“访问权限”更改为“读取、写入和访问直接消息”，并在“其他权限”中启用“向用户请求电子邮件地址”。

最后，单击“更新设置”保存更改。
