我正在尝试让Google登录以与我的应用一起使用。到目前为止，我认为我已经正确地完成了所有操作。我遵循了有关设置googlesigninclient的google文档的说明，可以使该应用进入登录按钮，但是当有人尝试登录时，它会返回12500错误（SIGN_IN_FAILED）。我已经正确设置了google api凭据，并且已经在我的debug.keystore中正确设置了Google api凭据，并且在我的应用文件夹中下载了certificate.json文件。我将发布我的代码，有人知道为什么它不起作用吗？
谢谢！
P.S。只是为了避开通行证，我在我的手机上进行了测试，该手机肯定具有最新版的Google Play服务，所以我认为这不是问题

对我来说是因为我启用了Google Play应用签名，所以您必须从发布管理-> 应用签名-> “应用签名证书” 部分
答案 1 :(得分：0)
只需将您的Google Play服务更新到最新版本。如果您使用的是AVD，则Nexus 5和5X图像均支持Google Play。模拟器启动并运行后，进入“扩展控件菜单”> Google Play，然后进行更新。

错误代码10为DEVELOPER_ERROR： https://developers.google.com/android/reference/com/google/android/gms/common/api/CommonStatusCodes.html#DEVELOPER_ERROR
这几乎可以肯定意味着您没有在Google API控制台中正确注册SHA1和软件包名称： https://developers.google.com/identity/sign-in/android/start
如果您100％确保正确执行了此操作，请确保您的GoogleSignInOptions是正确的。特别是，请确保Web客户端ID（如果正在使用）与注册包名称和SHA1的项目属于同一项目。

这可能是一个较晚的答案，但对某些人有帮助。为您的项目启用Firebase。请按照以下步骤设置Android应用。 确保您已提供支持电子邮件。在我的情况下，这是问题所在，并提供了有效的电子邮件，请解决该问题。
