新しい sqlite データベースの作成に問題があります。ほとんどの場合は機能しますが、Samsung Galaxy S III を使用している一部のお客様から、アプリケーションのインストール後にクラッシュが報告されています。問題は、sqlite がwrite()メソッドを呼び出すときであり、お客様が exFAT でフォーマットされた外部 SD カードを持っている場合にのみ発生することがわかりました (Samsung は一部の携帯電話でサポートしています)。奇妙なことは、フォルダーの作成が機能し、空のデータベースファイルの作成も機能し、その後クラッシュすることです。これは、Samsung のストック ROM でのみ発生します。exfat を使用したカスタム ROM では、完全に機能します。この問題を解決するには？ありがとうございました
