扑动未处理的异常：PlatformException（sign_in_failed，com.google.android.gms.common.api.ApiException：10：，null）

Question

我想用 Google 帐户登录我的应用，但我得到了

我有 key.jks 并添加到 Firebase sha-1 和 sha-256 然后更新 google-services.json。我运行 Flutter 干净。我在 Firebase 中启用了 Google 的权限。

我该如何解决这个问题。

我想我尝试了所有解决方案......

Answer 1

当应用程序的签名证书的 SHA-1 在 OAuth2 客户端和应用程序的 API 密钥上未正确配置时，会导致从 Google 登录引发的“ApiException 10”。 https://www.google.com/search?q=firebase+auth+apiexception+10

如果您在调试时运行应用，如之前在 cmets 中所述，您需要在 Firebase 项目的应用设置中添加 SHA-1 generated from the debug keystore。如果应用在发布时运行也是如此，应该添加发布密钥库中的 SHA-1。
