現在、firebaseデータベースに名前、電子メール、パスワード、年齢を正常に挿入していますが、選択したラジオボタンから値を挿入しようとするまで、悪夢が私に届きました。問題はデータがデータベースに挿入されることがありますが、認証部分でさえも挿入できないため、この問題をどのように解決できるのでしょうか？なぜfirabase認証からのgetidにエラーがありますか？

logcatは
のjava.lang.NullPointerExceptionを示しています、引数 'pathString' の
をnullを渡すことはできません。この問題を解決するために私をアドバイスしてください。 挿入するときにアプリケーションが動作しなくなり、今度はレジスタページ全体が表示されなくなりました。
ただし、リスナーはどこに挿入しますか？ –
あなたの活動の 'onCreate'にはそれが問題ありません。 –
