Delete/Erase a particular url from Android web view history?

Is it possible to erase a specific url from the android's webview history? I Google a lot but was not able to find any sol, even i checked the api's documentation and i think there is no direct way to do the same. have a look at below code:

// getting the whole list of web view's history....
WebBackForwardList list = wv.copyBackForwardList();
// getting previuous item/link 
String lastUrl = list.getItemAtIndex(list.getCurrentIndex()-1).getUrl();

From 2nd line of code it is clear that it is possible to play around with history, so i think there must be some way or trick to delete a particular link from web view history. Does it makes any sense to you guys?

Any code snippet or any link will highly be appreciated.

thanks,
