が、私は例外を取得しています理由を知りたい私のDatabaseHelperクラスですか？辞書ファイルのサイズが例外を引き起こしていますか？そして、その解決策は何ですか？

show full stack trace –

あなたのlogcatを見せてください。 –

私はあなたがそのような大きなファイルでプログラムスタックを過負荷にしていると思います。しかし、スタックトレース全体を表示するには –

ArrayList<WordDefination> getAllWords()とArrayList<WordDefination> getAllWords()の方法でCursorを終了していないことがわかりました。だから、あなたはどのようにして何回呼んだのだろうか？

さらに、データベースが大きいため、SELECT * FROM "+DICTIONARY_DATABASE;のデザインが悪いです。

最初のカーソルに問題がありますが、終了しませんでした。

あなたのコードで静的を避けることについては、非常に必要な場合は使用してください。メモリ不足の問題もあります。アンドロイドアプリでメモリを最適化する方法については、こちらをご覧ください。ここにはlink
