Android 4.2.2 でプロジェクトを起動しようとすると問題が発生します。スタックトレースは次のとおりです。

これは Android 4.0.4 では正常に機能しましたが、Android 4.2 で起動すると、その例外で常にクラッシュします。私は公式の Web サイトで sqlcipher のソースを提供していますが、それが私が取得した最後のソース (名前は SQLCipher+for+android+2.2.0) であることを願っています。このプロジェクトの最新バージョンは見ていません。
回答をお寄せいただきありがとうございます（検索して回答が見つからない重複した質問ではないことを願っています...）
