difference between loadData() and loadDataWithBaseURL() in WebView class.....?

can anybody tell me the difference between loadData() and loadDataWithBaseURL() in WebView class.

when i used 开发者_运维百科web.loadDataWithBaseURL("",html, mimetype, encoding,""); in my program , where html is the string that contains hard coded html tags, its displaying just like as html page where as when i used loadData(html,mimetype,encoding) in my code the application is closing.

i read the API but could not understand it..... so please help me...

Thanks in Advance

In case someone comes across this, WebView.loadData seems to be broken:

Variants of the solution suggested in the OP's question seems to be the workaround. I figure nulls are cheaper than "", so I used this:

web.loadDataWithBaseURL(null,html, "text/html", "utf-8",null);
