如您所见，这是我的代码，主要是从谷歌文档复制的，用于谷歌登录身份验证。问题是，当我单击登录按钮时，它会向我抛出一个名为“16：”的错误：抱歉发布图像，我在发布代码时遇到问题，希望有人可以帮助我解决这个问题。

我也有同样的问题。这是我的解决方案。希望你能理解。
情况：当出现错误代码“16：”时，如何解决此问题，卡在“使用 Google 登录”处，在消息框中按下我们的电子邮件后，没有出现下一个活动，而只出现错误。
5.2。要解决这个问题：
5.2.1。从您的项目 (Android Studio) 获取 SHA1
5.2.2。创建 API 密钥和 OAuth 2.0 客户端 ID（Android 类型）。 （https://console.cloud.google.com/apis/credentials）
5.2.3。因此，数据是在 Google 设置的，因此请在 https://console.firebase.google.com/（在项目设置中）获取新的 Firebase 控制台 google.json。下载然后替换。
5.2.4。关闭 Android Studio，重新打开，然后“Make Project”
5.2.5。冲着电话跑。成功了！
请参阅此链接：谷歌登录无法在发布模式下工作apk android
有关 google api 的更多信息：https://developers.google.com/maps/documentation/android-sdk/config （为manifest.xml添加额外的东西）
在将 Android 上的 Google SignIn 与 Firebase 集成时，我还看到了“错误代码 16”。仍然不确定我错过了什么，但我回到开头并遵循这个文档：
https://firebase.google.com/docs/auth/android/google-signin
这个链接非常完整。我不需要在 Google Cloud 控制台中配置任何内容。 我确实使用了上面页面链接到的Integrating Google SignIn页面上的信息，并获取了按钮的代码和布局。
经过大约 48 小时的努力解决了 firebase google 登录错误 16 凭证不匹配；
解决我问题的唯一方法是通过此链接使用“配置 Google API 控制台项目”获取您的 web_client_id https://developers.google.com/identity/sign-in/android/start-integrating#configure_a_project ，您应该提供 AndroidManifest.xml 中的应用程序 id 和 android studio 签名报告中的 sha1。
此外，我为每个 android studio 项目设置了不同的 sha1，以避免 firebase 中的任何冲突，这是通过在应用程序 build.gradle 中的 android {} 中的signingConfigs {} 中设置调试参数来实现的，如下所示
android {
signingConfigs {
debug {
storeFile file("path_to_keystore.jks")
storePassword "keystore_password"
keyAlias "key_alias_name"
keyPassword "key_password"
}
}
}
此外，我建议先尝试不使用 Firebase 进行 google 登录，给你正能量，然后根据需要再使用 firebase google 登录。
希望这可以帮助每个面临同样错误的开发人员并节省他们的时间。
当然，这是 Stack Overflow 的回复翻译：
在开发我的应用程序期间，我遇到了以下错误：
com.google.android.gms.common.api.ApiException: 16: [16] Account reauth failed
我尝试了几种建议，包括生成新的 API 密钥和检查配置，但事实证明主要问题是设备上缺乏互联网连接。
解决方案：确保运行应用程序的设备具有有效的互联网连接。就我而言，恢复互联网连接后错误消失了。
我希望这可以帮助人们节省故障排除的时间。
