should
Called when the HTML converter wants to loads a resource (image, stylesheet, JavaScript etc.).
This method is invoked for most supported URI schemes ("http(s):", "file:" etc.) and is not limited to requests made over the network. This is not called for "javascript:", "data:" and "blob:" schemes as well as for Android assets ("file:///android_asset/") or Android resources ("file:///android_res/").
If the source requires redirects, this method is called only for the initial base URL, not for the redirect URLs.
This method is called on the background thread.
Return
Response for resource request with resource data, null to proceed with loading the resource as usual and skipResource to skip loading the resource.
