三种方法解决android帮助文档打开慢

三种方法解决android帮助文档打开慢

 

经查是因为本地文档中的网页有如下两段js代码会联网加载信息，将其注释掉后就好了

 

<link rel="stylesheet"

href="http://fonts.googleapis.com/css?family=Roboto:regular,medium,thin,italic,mediumitalic,bold" title="roboto">

 

 <script src="http://www.google.com/jsapi" type="text/javascript"></script>

用以下java代码就可以批量注释

/*

 * 去掉Android文档中需要联网的javascript代码

网上有种方法是通过shell删除那行js代码，非常简洁方便，比上面的的java方便100倍，不过不能删掉第一段js代码

find . -name "*.html"|xargs grep -l "jsapi"|xargs sed -i '/jsapi/d'

还有的方法是断网，或者用IE，firefox脱机浏览
