html code: 

<div><a href="http://www.sotkora.com/xy/images/rose.jpg" download="jpgphoto">download jpg photo</a></div><br/>         <div><a href="http://www.sotkora.com/xy/files/load_test.pdf" download="pdf_test">download pdf file</a></div><br/>         <div><a href="http://www.sotkora.com/xy/files/load_test.zip" download="zip_test">download zip file</a></div><br/>

if using proper headers downloading should able following... (you need implement own download process)

mwebview.setdownloadlistener(new downloadlistener() {     public void ondownloadstart(string url, string useragent,             string contentdisposition, string mimetype,             long contentlength) {         // download via android code     } });
