Question

我有两个登录选项，普通登录和google登录。普通登录可以正常工作，但google登录不是。

我点击google登录按钮，我可以看到这些帐户。因此，我单击了该帐户，但是什么也没有发生。而且我也看不到firebase上的用户数据。

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

我正在关注this tutorial的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

来自Google登录的空响应通常是由于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 并且包含指向集成教程中标准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 您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，则通常将其命名为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（如果您有多个项目），则Google登录将正常运行。

您还使用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;
            }
        }
    }
}

通过这种方式，您将能够了解登录为什么不起作用
