Unhandled Exception: PlatformException (sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null, null) - works well in one system

Question

我正在使用 flutter 中的平台通道（使用 Java）開發藍牙應用程序。 但是，當我嘗試使用 google-sign in( google_sign_in: ^4.5.6 ) 登錄時，我遇到了錯誤。 我可以登錄詳細信息，但無法移至更多頁面......實際上，它在我的辦公系統中工作，但是當我復制項目並在另一個項目中運行時，它給出了錯誤......任何人都可以幫忙

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 means it's most可能是由於 SHA-1 或 SHA-256 設置不正確。 既然您說它在辦公室工作，它可能與您現在使用的環境不同，您應該添加這些密鑰。 這也假設您正在運行調試版本，因此添加您的調試 SHA-1 密鑰。

Answer 2

從 Google Play 下載的應用程序也會出現此問題。 這是因為 Google 使用自己無法訪問的密鑰為您的應用程序簽名。 您可以從以下位置獲取它的 SHA1：Google Play Console -> Your App -> App Integrity。

Answer 3

最近經過多次嘗試修復了這個問題，在更新到flutter-3.1.0-pre9，並將Android studio更新到chipmunk 2021.2.1后，我收到了一條有趣的調試消息。 google sign in iOS 上運行良好，但無論我做什么，我都會收到這個確切的消息PlatformException (sign_in_failed... blah blah blah

新的錯誤消息現在也有： clientId is not supported on Android and is interpreted as serverClientId. Use serverClientId clientId is not supported on Android and is interpreted as serverClientId. Use serverClientId

在 Android 上添加clientId作為參數似乎是問題所在

確保您的密鑰庫sha-1已在 firebase 上注冊，並且您已完成 firebase 上所述的說明

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);
 ***

這樣，您可以在 iOS 上設置clientId ，在serverClientId上設置 serverClientId。 希望這有幫助。
