如何在数据库中保存身份验证后的用户电子邮件和姓名 (Firebase)

Question

我是Android新手，也是Firebase新手。我正在开发一个Android应用程序，用户可以在其中使用电子邮件和密码创建他的帐户。

如何将用户身份(如姓名、地址等(以及电子邮件保存到 Firebase 数据库中？

这是我的代码，其中使用电子邮件和密码创建用户，并代码以获取有关要保存在数据库中的用户的额外信息。

我的应用程序在创建新用户后崩溃，并且它没有在数据库中存储信息。

auth.createUserWithEmailAndPassword(emailId, password)
    .addOnCompleteListener(MainActivity.this, new OnCompleteListener<AuthResult>() {
        @Override
        public void onComplete(@NonNull Task<AuthResult> task) {
                if (task.isSuccessful()) {
                    String user_id = auth.getCurrentUser().getUid();
                    DatabaseReference current_user_db = reference.child(user_id);
                    current_user_db.child("FNAME").setValue(nameF);
                    current_user_db.child("LNAME").setValue(nameL);
                    current_user_db.child("EMAIL").setValue(email);
                    progress.hide();
                    Intent intent = new Intent(MainActivity.this, ProfileActivity.class);
                    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                    startActivity(intent);
                }
        }
    });

这是日志。

尝试使用哈希图(我个人认为它更具可读性(这是我更新用户设置的代码，整个函数通过按钮调用，希望这有帮助。

private void updatesettings() {
    String UserName = username.getText().toString().toLowerCase().trim();
    String PhoneNumber= pno.getText().toString();
    FirebaseUser user = mauth.getCurrentUser();
    String uid = user.getUid();
    //this is to enter all the details under the UID of currently logged in user
    dbr = FirebaseDatabase.getInstance().getReference().child("Users").child(uid);
    HashMap<String, String> userMap = new HashMap<String, String>();
    userMap.put("name", UserName);
    userMap.put("phone number", PhoneNumber);
    userMap.put("status", "jdjdjjdjdjdj");
    userMap.put("image", "default");
    userMap.put("thumbnail", "default");
    dbr.setValue(userMap).addOnCompleteListener(new OnCompleteListener<Void>() {
        @Override
        public void onComplete(@NonNull Task<Void> task) {
            if(task.isSuccessful()){
                // Toast.makeText(UpdateUserSettings.this, "Your settings have been updated", Toast.LENGTH_LONG).show();
                startActivity(new Intent(UpdateUserSettings.this, MainActivity.class));
            }
            else{
                Toast.makeText(UpdateUserSettings.this, task.getException().getMessage(), Toast.LENGTH_LONG).show();
            }
        }
    });
}
