Question

我使用Facebook SDK 将本地的Android 应用程序连接到脸书上。我能够显示登录页面, 让用户通过脸书账户登录我的应用程序。但根据以下信息: < a href="https:// developingers.facebook.com/docs/move/android/building/ #sso' rel=“nolfollow” >https://developers.facebook.com/docs/mobile/android/building/#sso

我必须留意两项活动,例如取消访问和更改密码。响应参数将返回以下结果:

User revoked access to your app: {"error":{"type":"OAuthException","message":"Error validating access token: User 1053947411 has not authorized application 157111564357680."}}

OR when password changed: {"error":{"type":"OAuthException","message":"Error validating access token: The session is invalid because the user logged out."}}

现在,我的问题是,我如何处理或抓住以下错误?谢谢。

有这方面的正式指南:Handling 无效和过期存取 Tokens 。

它说:

< 坚固 > Android本地应用程序

You may detect access token errors by inspecting the response parameter of the onComplete method. In this case, you will again need to call facebook.authorize() to re-authenticate the user and generate a fresh access token.
