新しい文書に書き込むためにpdf writerを作成するPdfWriter.getInstance（document、new FileOutputStream（FILE））; \t \t \t \t \t \t \t \t \t \t document.open（）;マニフェストのパーミッションを宣言しました –
@peter上記のコードではすでにpdfwriterのインスタンスを作成していますが、すでにマニフェストの外部ストレージを読み書きする権限を与えています。マニフェストで宣言しなければならない他の許可はありますか？ –
あなたのPDF作成コードは広範囲に広がっており、外部から与えられたデータに依存して問題を試して再現することはできません。静的テキストに基づいてPDFを作成する作業（UIイベント処理は不要）に集中するようにコードを減らしてください。 – mkl
