I Ajeet,
In one of my apps, I load an HTML page as follows:
webView.loadUrl("file:///android_asset/help/helpgube.html");
Below is a snippet from the helpgube.html:
<head>
<meta http-equiv="content-type" content="text/html;
charset=utf-8" />
<link type="text/css" rel="stylesheet" id="helpCSS" href="./
helpgubecss.css" />
</head>
And here a snippet from helpgubecss.css
body {
BACKGROUND-POSITION: 0px 0px;
BACKGROUND-IMAGE: url(../images/screen1_trans.png);
BACKGROUND-REPEAT: repeat-y;
BACKGROUND-COLOR: transparent
}
As you can see, all internal links to CSS and images are relative. My
code does not use loadDataWithBaseURL. However, i think the form of
the url may be the key: "file:///android_asset/"
