我需要你的帮助......我不知道了！
我不明白为什么每次都失败了。
google-services.json移动到./app文件夹中。退房，如果有什么伤害你......继续！
亲切的问候

从您的代码中，替换
gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail()
.build();
有了这个：
gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken("web client id from console.developers.google.com for the app")
.requestEmail()
.build();
希望这能有所帮助。还有Firebase Signin变得更容易。检查这个link了。谢谢
对我而言，当应用程序使用不正确的证书进行签名时，证书SHA-1必须在Google控制台中注册。
对于Debug构建变体，您可能还希望将调试证书添加到Google控制台，或者将build.gradle配置为调试变体以使用您在控制台中注册的相同证书。
