How many WebViewExtras libraries are there currently available? I am trying to receive an event when there is an error while accessing a website. I currently have the 1.42 version installed but I am getting hits in this forum that uses a library by this name that has the onReceivedError event available. I do see a version 2.2, WebViewExtras2, that I downloaded from a different website. Is this the library that I need or is there another version of this library that I haven't discovered yet?
