Android 參考文檔本地打開緩慢，JAVA解決方案

關於Android Develop 文檔明明本地下載了，但在瀏覽器里打開還是很卡，原因是html文檔中有鏈接Google伺服器的Link和script。

網上有很多解決方案，其中一種是刪除裡面所有鏈接Google伺服器的Link和script。

我在網上下載的JAVA代碼這兩行修飾css代碼是怎麼也刪不掉，後來我讀完代碼發現有些bug.

<link rel="stylesheet"
href="http://fonts.googleapis.com/css?family=Roboto+Condensed">
<link rel="stylesheet" href="http://fonts.googleapis.com/css?family=Roboto:light,regular,medium,thin,italic,mediumitalic,bold"
title="roboto">

以下是我參考別人的代碼修改的JAVA代碼解決方案，與別人JAVA代碼的不同之處是能完全刪除所有鏈接Google伺服器的Link和script。

        String content = FormatDoc.read(f);
        content = content.replaceFirst(src, dst);

        System.out.println(ll);
        FormatDoc.write(content, f);
