私は firebase-UI を使用して twitter にログインしていますが、ドキュメントにあるように、メソッドを使用してアクセス トークンを取得する必要があります private void handleTwitterSession(TwitterSession session) 。ログインは正常に機能していますが、いわゆる「セッション」と呼ばれるその機能に何を送信すればよいかわかりません。FirebaseAuth mAuth オブジェクトからアクセス トークンを取得するにはどうすればよいですか??...どうもありがとうございました。ドキュメントへのリンクはこれです https://firebase.google.com/docs/auth/android/twitter-login
