我有一个系统可以将 createUserWithEmailAndPassword 数据保存到实时数据库和身份验证数据库中。但是在使用谷歌登录创建了一个类似的系统之后，没有任何内容会保存到数据库中，也没有任何内容保存到身份验证数据库中。

我试过使用 Log.e，我试过调试应用程序，也试过解码代码...

这里是一些代码:

                                    Log.e("SignUpError :", task
                                            .getException()
                                            .getMessage());


                                }
                            }).addOnFailureListener(new OnFailureListener() {
                        @Override
                        public void onFailure(@NonNull Exception e) {
                            Toast.makeText(LoginOrSignupActivity.this, "Registration failed", Toast.LENGTH_SHORT).show();
                            Log.e(Tag, "error: ");
                        }
                    });

                }

            }

            @Override
            public void onCancelled(@NonNull DatabaseError databaseError) {

            }
        });

    }

    void LoadinGUI(){

        LoginBtn = (Button) findViewById(R. id. Login_btn);
        RegisterWithEmailBtn = (Button) findViewById(R. id. Register_WithEmail_btn);
        RegisterWithGoogleBtn = (Button) findViewById(R. id. Register_WithGoogle_btn);

    }

}

我希望应用程序将信息保存到实时数据库和身份验证数据库中。这些似乎都不起作用......

最佳答案

登录成功后忘记调用SaveToDataBase。这就是为什么没有日志和数据库条目的原因。

关于java - Firebase Auth 和 Firebase 数据库不保存 Google 注册，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/56957729/
