what's the purpose of WebViewClient.onLoadResource

I would like to ask the purpose the

WebViewClient.onLoadResource

even we can get this callback when webkit tries to load resource but since its return type is void

what ca开发者_Python百科n we anything in this function???

I know in API 11 there's a shouldInterceptResouce but how about for those froyo/gingerbread devices?

thanks

From the docs:

Notify the host application that the WebView will load the resource specified by the given url.

So, you can override it in your implementation of WebViewClient, for example, to cache resources for future use in your application.
