android - Firebase 谷歌身份验证不工作。 ApiException : 12500: , 空

Question

是的一切都在 firebase 和 flutter 中设置得很好1)在firebase项目中添加了最新的SHA-1指纹2) 启用谷歌登录选项3) 添加了支持的邮箱

应用程序仍在调试中添加调试 key SHA-1

没有任何效果

我只是想设置一个我无法登录的简单 Google Auth 登录

我遇到了这个错误

平台异常(登录失败，com.google.android.gms.common.api.ApiException:12500:，空)

`

final FirebaseAuth auth = FirebaseAuth.instance;
  final GoogleSignIn googleSignIn = new GoogleSignIn();

  GoogleSignInAuthentication googleAuth;


  Future<FirebaseUser> SignInWithGoogleAuth() async {

    GoogleSignInAccount GSA = await googleSignIn.signIn();
//I'm getting error here  ^^ at the above line code
     googleAuth = await GSA.authentication;
     AuthCredential credential = GoogleAuthProvider.getCredential(
      accessToken: googleAuth.accessToken,
      idToken: googleAuth.idToken,
    );
     FirebaseUser user = await auth.signInWithCredential(credential);
    assert(user.email != null);
    assert(user.displayName != null);
    assert(!user.isAnonymous);
    assert(await user.getIdToken() != null);
    final FirebaseUser currentUser = await auth.currentUser();
    assert(user.uid == currentUser.uid);
    print('signInWithGoogle succeeded: $user');
    return currentUser;

  }

错误:

Answer 1

我有这个错误 ApiException: 12500 很长时间了。我已经尝试了一切:

• 删除我的调试 keystore ，重新创建一个
• 在 Firebase 控制台上添加支持电子邮件
• 更改插件版本
• 在我的设备上更新谷歌

除了寻找我找到的解决方案外没有任何效果:

我去了这个页面 ( https://console.developers.google.com/apis/credential s)从列表(左上角)中选择您的项目。然后转到“Oauth 同意屏幕”

我在应用主页上填写了应用的标志和链接以及应用的隐私政策链接(与project.firebaseapp.com)，然后保存。

之后就好了。我认为应该更新官方文档。
