android - Facebook がフィードに公開しない

Question

https://developers.facebook.com/docs/android/publish-to-feed/の例を使用して、アクティビティから投稿を公開しようとしています。アプリがユーザーのウォールに投稿することを許可しますが、投稿をニュースフィードまたはウォールに公開していないため、投稿されたストーリー ID で成功アラートが表示されません。問題は何ですか？ログインフォームは別のアクティビティにあり、ユーザーがこのアクティビティでFacebookにログインする必要がないため、ユーザーがこのアクティビティに移動する前にセッションを有効にしたいことに注意してください。コードは次のとおりです。
