我想通过Office365进行身份验证以使用Exchange Web服务。
我正在使用https://github.com/Azure-Samples/active-directory-android
中的Active Directory Android示例我在Azure AD中注册了一个客户端，并在示例中输入了client_id，现在可以成功访问Graph API。
当我想访问EWS时，我将resource_id更改为https://outlook.office365.com/。 Web视图中的身份验证页面指的是我的应用程序名称，我被要求授予我的应用程序访问邮箱等（长列表）的权限，但是当我接受时，我没有获得授权令牌。 抛出IOException，并且示例崩溃，因为onError中的异常为null。 这是控制台输出：
