在Android上使用Firebase设置Facebook身份验证，并收到以下令人讨厌的错误：
com.google.firebase.FirebaseException: An internal error has occurred. [ Unsuccessful debug_token response from Facebook:{"error":{"message":"Invalid OAuth access token signature.","type":"OAuthException","code":190,"fbtrace_id":"BLR\/UAx2fzn"}} ]
我的目标不是要消除此错误，而是要能够从Firebase获取有关用户的信息。目前，即使我似乎能够获得一个非空，未过期的令牌，但我的Firebase控制台中没有Facebook用户的条目。 IOW，如何使这条线不失败？
-> mAuth.signInWithCredential(credential)
为重现，我从头开始（注销）启动该应用程序，然后继续执行我的LoginActivity。我选择继续使用Facebook LoginButton，然后选择继续。我目前有我的应用程序逻辑，因此回调成功后，它停留在LoginActivity中，并且出现上述错误。

我注意到，当我在回调中包含行handleFacebookAccessToken(loginResult.getAccessToken());时，我得到了错误，但否则没有。但是排除该行似乎不是永久性的解决方案，因为那我该如何检索用户信息？
答案 0 :(得分：0)
我最终通过以下方式解决了这个问题：
（请打鼓）
通过Facebook开发者控制台删除我的Facebook应用程序，并创建一个新的相同应用程序。然后，我将应用程序ID和密码复制到Facebook登录的Firebase控制台auth中，更新了清单，然后就可以了。
我没有将此解决方案标记为“正确”的答案，因为它没有“解决问题”。我已经直觉地认为这是FirebaseException（内部错误），在我已经三重翻两番检查了我所有的Facebook应用程序的配置设置和代码之后。
