Android 将AppAuth用于Twitter、Paypal&；Linkedin登录

我无法成功地使用其中任何一个

Twitter配置

 {
  "client_id": "",
  "redirect_uri": "https://callback.com/landing/twitter/login",
  "authorization_scope": "read",
  "discovery_uri": "",
  "authorization_endpoint_uri": "https://api.twitter.com/oauth/authorize",
  "token_endpoint_uri": "https://api.twitter.com/oauth/token",
  "registration_endpoint_uri": "",
  "user_info_endpoint_uri": "https://api.twitter.com/1.1/account/verify_credentials.json",
  "https_required": true
}

twitter的错误是

贝宝配置

{
  "client_id": "",
  "redirect_uri": "https://callback.com/landing/paypal/login",
  "authorization_scope": "openid email phone address profile",
  "discovery_uri": "",
  "authorization_endpoint_uri": "https://www.paypal.com/signin/authorize",
  "token_endpoint_uri": "https://api.paypal.com/v1/oauth2/token",
  "registration_endpoint_uri": "",
  "user_info_endpoint_uri": "https://api.paypal.com/v1/oauth2/token/userinfo",
  "https_required": true
}

贝宝我可以打开页面并登录。我在授权代码交换中失败

Linkedin配置

{
  "client_id": "",
  "redirect_uri": "https://callback.com/landing/linkedin/login",
  "authorization_scope": "r_basicprofile r_emailaddress rw_company_admin w_share",
  "discovery_uri": "",
  "authorization_endpoint_uri": "https://www.linkedin.com/oauth/v2/authorization",
  "token_endpoint_uri": "https://www.linkedin.com/oauth/v2/accessToken",
  "registration_endpoint_uri": "",
  "user_info_endpoint_uri": "https://api.linkedin.com/v2/me",
  "https_required": true
}

linkedin继续登录，重定向页面打开，代码在url中。水流停止在那里。那么我需要在服务器上捕获它吗？还是阿帕斯会处理？在Android Oreo上测试

有什么建议吗
