我已经成功地在我的 Android 应用程序中使用 Firebase 身份验证实现了谷歌登录。

如您所见，我已使用我的帐户登录并显示在 Firebase 控制台上。

使用 Google Sign-in 登录后，函数firebaseAuthWithGoogle使用 Firebase 对用户进行身份验证：

private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {
    Log.d(TAG, "firebaseAuthWithGoogle:" + acct.getId());
AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
mFirebaseAuth.signInWithCredential(credential)
        .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
            @Override
            public void onComplete(@NonNull Task<AuthResult> task) {
                if (task.isSuccessful()) {
                    // Sign in success, update UI with the signed-in user's information
                    Log.d(TAG, "signInWithCredential:success");
                    final FirebaseUser user = mFirebaseAuth.getCurrentUser();


                    //This is to connect to the http server and save the user data …

在使用本地 Firebase 函数模拟器作为我的后端设置我的项目，并从我的 Android 模拟器调用我的 Firebase onCall 函数后，我收到了这条非常无信息的错误消息PlatformException(functionsError, Cloud function failed with exception., {code: INTERNAL, details: null, message: INTERNAL})。完整的错误信息如下：
