Java Firebase 谷歌一键登录找不到匹配的凭据

发布于04月05日

我想使用Google帐户登录我的应用程序.我使用Firebase对用户进行身份验证.

I've already read the documentation like million times. I've added SH1 debug key to Firebase project as a fingerprint and I use Web SDK configuration from the Firebase as a web client id:

我已经将其设置在strings.xml文件中

<string name="web_client_id">**HERE**</string>个

我的其余代码如下所示:

public class AuthFragment extends Fragment {
    private FragmentAuthBinding binding;
    private SignInClient oneTapClient;
    ActivityResultLauncher<Intent> oneTapLauncher = registerForActivityResult(new ActivityResultContracts.StartActivityForResult(),
        result -> {
            if (result.getResultCode() == Activity.RESULT_OK) {
                Intent data = result.getData();
                try {
                    var credential = oneTapClient.getSignInCredentialFromIntent(data);
                    String idToken = credential.getGoogleIdToken();
                } catch (ApiException e) {
                    throw new RuntimeException(e);
                }
            }
        });
    public AuthFragment() {}

    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        binding = FragmentAuthBinding.inflate(inflater, container, false);
        return binding.getRoot();
    }

    public void onViewCreated(@NonNull View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        
        HandleGoogleLogin();
    }

    @Override
    public void onDestroyView() {
        super.onDestroyView();
        binding = null;
    }

    void HandleGoogleLogin()
    {
        oneTapClient = Identity.getSignInClient(requireActivity());
        var signInRequest = BeginSignInRequest.builder()
                .setGoogleIdTokenRequestOptions(BeginSignInRequest.GoogleIdTokenRequestOptions.builder()
                        .setSupported(true)
                        .setServerClientId(getString(R.string.web_client_id))
                        .setFilterByAuthorizedAccounts(false)
                        .build())
                .build();

        var googleLoginButton = binding.googleLoginButton;
        googleLoginButton.setOnClickListener(v -> {
            oneTapClient.beginSignIn(signInRequest)
                    .addOnSuccessListener(requireActivity(), result -> {
                        var intentSenderRequest = new IntentSenderRequest
                                .Builder(result.getPendingIntent().getIntentSender())
                                .build();
                        oneTapLauncher.launch(intentSenderRequest.getFillInIntent());
                    })
                    .addOnFailureListener(requireActivity(), e -> {
                        Log.d("googleLoginButton", "oneTapClient.beginSignIn:onError - " + e.getMessage());
                        // Handle errors or continue presenting the signed-out UI
                    });
        });
    }
}

这并不是我试图实现它的唯一方式.我还try 将SH1键添加到https://console.cloud.google.com/，并从https://console.cloud.google.com/apis/credentials?project=myproject站点配置OAuth 2.0:
