クライアントの場合、Sencha Touch と Cordova を使用してネイティブ アプリケーションを構築する必要があります。
パフォーマンスのために、SDK Tools for miniified javascript source のコマンド「sencha app build package」を使用します。
開発にSencha、webviewにCorovaを使えば問題ありません。しかし、Sencha ではできない Cordova 関数 (FileSystem など) を使用する必要があります。
問題は、「sencha app build package」を使用すると、 のようなエラーが発生することです[ERROR] ReferenceError: Can't find variable: fileSystem。
Sencha + Cordova について話している記事をたくさん読みましたが、Cordova + Sencha を使用したビルド/ミニファイド ソースについて話している記事はありません。
この問題に直面した人はいますか?どのように解決しましたか?
よろしくお願いします

Cordova 変数にアクセスする必要があるすべてのメソッドに CordovaFunctions.js というファイルを使用し、app.js と他のビュー/コントローラーが CordovaFunctions.js のメソッドを呼び出します ...
ここに私の app.json があります:
