我注意到使用NATIVE_WITH_FALLBACK模式，并更改WEB_ONLY为测试。尽管这使我摆脱了上图所示的原始问题，但它又产生了另一个问题。它没有询问我登录详细信息，而是显示了以下内容：

在此处输入图片说明

同样，文字是：

您先前使用Facebook登录到$ MY_APP。你想继续吗？

如果我选择继续（别无选择，只能取消），它会返回我的应用程序，但是Firebase会给我ERROR_ACCOUNT_EXISTS_WITH_DIFFERENT_CREDENTIAL错误，提示该帐户已与另一个提供程序关联。当我在Firebase控制台中签入时，该帐户显示为Facebook帐户。因此，就像安装了Facebook应用程序一样，Firebase认为它是单独的社交服务提供商或其他某种服务。

最后，出于绝望，我尝试将身份验证模式切换为WEB_VIEW_ONLY。果然，这向我展示了与未安装Facebook时登录完全相同的体验。而且，一切都按预期进行。

我的问题是我不确定所有这些含义是什么（注意：请参阅下面的更新）。我记得曾经读过一些有关本地Facebook登录的信息，但不再是真的（或者相反，应该使用它）。基本上，我很困惑，非常感谢您回答以下问题：

  • 使用WEB_VIEW_ONLY可接受的方法吗？
  • 为什么使用NATIVE_WITH_FALLBACK会在帖子开头显示错误？
  • 为什么WEB_ONLY似乎会将同一帐户视为不同的提供商？
  • 为什么Facebook登录SDK在这些模式下的行为如此不同？我认为它们是无害的偏好，它对身份验证本身没有任何影响，但是我错了。

请注意，在所有情况下，我都会使用官方文档，包括使用最新的SDK版本：

implementation 'com.facebook.android:facebook-login:[5,6)'

感谢您的协助。

更新：我将我的应用程序更新为，WEB_VIEW_ONLY然后重新提交。Facebook现在告诉我：

您的应用现在违反了平台政策8.2：实现Facebook登录的本机iOS和Android应用必须使用我们的官方SDK进行登录。请确保您的应用使用的是我们最新版的SDK进行登录。

所以我现在陷入了困境。

请记住，您在 Facebook 应用程序中配置的密钥哈希与您的应用程序签名的密钥库（证书）相关。

您必须使用用于签署应用程序的密钥哈希，如果您不知道它，我建议您从密钥库中再次获取它：

为什么 Facebook 登录 SDK 在这些模式下的表现如此不同？我认为它们是一种无害的偏好，对身份验证本身没有任何影响，但天哪我错了。

在网络中，你不会\xc2\xb4t有问题，但如果你在一个应用程序中，你需要授权该应用程序的使用，这对于Android应用程序中的这个实现非常重要，你需要使用Facebook SDK，在这种情况下您需要获取用于签署您的应用程序的密钥哈希证书。

在你的日志顶部，它说
Key hash GtvUdcOKFRAE0RY0LIw5veCA+M8= does not match any stored key hashes.

当您构建发布时，您可能使用了错误的 keyhash。显然，当您使用错误的 keyhash（如本链接中所述）时，就会发生此问题。

至于为什么它在WEB模式下工作，是因为SDK检查了keyhash，并且由于您改为访问网页，因此您不会收到错误。您正在调试模式下运行，并且调试模式密钥哈希可能是正确的，这可能是它在您的设备上工作的原因的答案。
