未处理的异常：PlatformException (sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null, null) - 在一个系统中运行良好

Question

我正在使用 flutter 中的平台通道（使用 Java）开发蓝牙应用程序。但是当我尝试使用 google-sign in( google_sign_in: ^4.5.6 ) 登录时，我收到错误。\n我可以登录详细信息，但无法移动到下一页......\n实际上，它在我的办公系统中工作，但是当我复制该项目并在另一个系统中运行时，它给出了错误......任何人都可以帮忙吗

Answer 1

[ERROR:flutter/lib/ui/ui_dart_state.cc(186)] Unhandled Exception: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null, null)apiException:10 表示这很可能是由于 SHA-1 或 SHA-256 设置不正确造成的。既然您说它在办公室工作，那么它可能与您现在使用的环境不同，您应该添加这些键。这还假设您正在运行调试版本，因此请添加调试 SHA-1 密钥。

Answer 2

从 Google Play 下载的应用程序也会出现此问题。这是因为 Google 使用自己的密钥对您的应用程序进行签名，而您无法访问该密钥。您可以从以下位置获取它的 SHA1：Google Play Console -> 您的应用程序 -> 设置 -> 应用程序签名

Answer 3

最近经过多次尝试修复了这个问题，在更新到 flutter-3.1.0-pre9 并将 Android studio 更新到chipmunk 2021.2.1 后，我收到了一条有趣的调试消息。它google sign in在 iOS 上运行良好，但无论我做什么，我总是收到这个确切的消息PlatformException (sign_in_failed... blah blah blah

新的错误消息现在也包含以下内容：clientId is not supported on Android and is interpreted as serverClientId. Use serverClientId

在Android上添加clientId为参数似乎是问题

确保您的密钥库sha-1已在 firebase 上注册，并且您已完成 firebase 上所述的说明

late GoogleSignIn googleSignIn;
***
@override
void initState() {
 ***
 googleSignIn = GoogleSignIn(
        scopes: [
          'email',
          'https://www.googleapis.com/auth/userinfo.profile',
        ],
        serverClientId: isIOS ? null : googleClientId,
        clientId: isIOS ? googleClientIdIOS : null);
 ***

您可以通过这种方式clientId在 iOS 和serverClientIdAndroid 上进行设置。希望这有帮助。
