Google登录未响应

Question

我有两个登录选项，普通登录和google登录。普通登录工作正常，但google登录不行。

我单击谷歌登录按钮，我可以看到帐户。所以我单击了帐户，但没有任何反应。此外，我在firebase上看不到用户数据。

我在模拟器或android studio上没有任何错误。我错过了一些东西，但是呢？

我正在按照本教程学习 Google登录方法。

更新错误日志

我终于找到了错误日志。问题是我每次都构建有签名的（release）apk，但是我在firebase上添加了调试SHA1代码。只是我在模拟器上运行了调试模式。

Answer 1

Google登录错误的响应通常是由于SHA指纹不正确，或者根本没有在Google API控制台中定义。 在视频中，作者使用了一个旧教程。 这是当前版本： https : //firebase.google.com/docs/auth/android/google-signin ，它包含集成教程中标准Google Sing的链接： https : //developers.google.com/identity / sign-in / android / sign-in

这是必需的，因为在本教程中还有另一个链接来配置Google API控制台： https : //developers.google.com/identity/sign-in/android/start-integrating通常需要在其中配置当前API项目的位置如果您更改了它或在API控制台中创建了其他项目，则它的名称为Google Play Android Developer或其他名称。

您需要在此处设置SHA-1指纹和软件包名称。 如果您将其设置为正确的项目（如果有多个项目），则Google登录将正常运行。

另外，您正在使用GoogleSignIn Client，因此在创建Sing In Intent时也必须使用它

private void signIn() {
    Intent signInIntent = mGoogleSignInClient.getSignInIntent();
    startActivityForResult(signInIntent, RC_SIGN_IN);
}

因此，请从Google查看本教程并按照文档所述实施本教程，一切正常。 https://developers.google.com/identity/sign-in/android/start-integrating

在onActivityResult回调内部，执行以下操作：

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == RC_SIGN_IN) {
        try {
            Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
            GoogleSignInAccount account = task.getResult(ApiException.class);
            // User is logged in on google platform
            Log.v(TAG, "Account token:" + account.getIdToken()); //NON-NLS
            // Signed in successfully, show authenticated UI.
        } catch (ApiException e) {
            // The ApiException status code indicates the detailed failure reason.
            // Please refer to the GoogleSignInStatusCodes class reference for more information.
            Log.w(TAG, "Google sign in failed", e); //NON-NLS

            String messageToDisplay = "Authentication failed.";
            switch (e.getStatusCode()) {
                case CommonStatusCodes.API_NOT_CONNECTED: //17
                    messageToDisplay += "The client attempted to clearPreferences a method from an API that failed to connect.";
                    break;

                case CommonStatusCodes.DEVELOPER_ERROR: //10
                    messageToDisplay += "The application is misconfigured.";
                    break;

                case CommonStatusCodes.ERROR: //13
                    messageToDisplay += "The operation failed with no more detailed information.";
                    break;

                case CommonStatusCodes.INTERNAL_ERROR: //8
                    messageToDisplay += "An internal error occurred.";
                    break;

                case CommonStatusCodes.INVALID_ACCOUNT: //8
                    messageToDisplay += "Invalid account name specified.";
                    break;

                case CommonStatusCodes.SIGN_IN_REQUIRED: //8
                    messageToDisplay += "Please Sign In to continue.";
                    break;
            }
        }
    }
}

这样，您就可以了解为什么登录无法正常工作
