我一直在我的Android应用中实施Firebase身份验证，并让它轻松运行成功（在调试中签名）为不同的身份验证提供商，如谷歌，但Facebook不会发挥作用。
尝试使用Facebook进行身份验证时，我一直收到com.google.firebase.FirebaseException。我正在使用github上的firebase/quickstart auth app中的示例。从下面的输出中可以看出，Facebook身份验证成功并且是有效的访问令牌。但是，当我将令牌传递给Firebase进行身份验证时，会抛出上述异常。

Facebook errors page会提示访问令牌或登录状态存在问题，但输出确认登录成功且访问令牌正常。我还使用Facebook Access Token debugger确认了令牌有效性，在输出中输入了令牌。
我正在用我尝试的所有东西撞墙砖，我彻底搜索并尝试了很多不同的解决方案，谷歌搜索了几个小时但没有到达任何地方。

您可以查看您的Facebook App ID＆amp; Firebase控制台中的密码设置是否正确？如果是，请在https://firebase.google.com/support/contact/bugs-features/
上提交Firebase身份验证错误答案 1 :(得分：1)
您最有可能在Firebase帐户中输入错误的应用凭据。请尝试再次复制它们。 关怀： - Facebook在设置标签中隐藏了应用秘密。单击show然后将其复制到您的firebase帐户，否则它将显示相同的错误。
