After lot more of digging i found the solution to it :
Spanned parsed = Html.fromHtml(text);
String finalstr = ("<html><body>").concat(parsed.toString()).concat("</body></html>");
mWebView.setInitialScale(30);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setLoadWithOverviewMode(true);
/*mWebView.getSettings().setLayoutAlgorithm(WebSettings.LayoutAlgorithm.SINGLE_COLUMN);*/
mWebVie.getSettings().setUseWideViewPort(true);
mWebView.loadData(finalstr, "text/html", "UTF-8");
This whole set of instructions helped me do the same.

Use regex.
<img.+?/>
will simply find image tags.

Learn XPATH
http://www.w3schools.com/xml/xpath_intro.asp
and use your xpath knowledge in
http://htmlcleaner.sourceforge.net/ , to get whatever you want from html

You can take advantage of the power of REGEX here.
Pattern pattern = Pattern.compile("/src=\"(.*)\"/");
Matcher matcher = pattern.matcher(YOURHTML);
matcher.group(1); // this way you can read all of the srcs
Disclaimer: the regex above is not tested.
