what does this return if no webviewclient is set?

It returns the sNullWebViewClient

[Nate Fischer, 2016/09/30 18:02:09]

This one gets initialized to sNullWebViewClient (a client created by the default
constructor), and mWebChromeClient is initialized to null. Should we change
these to be more consistent, or adjust documentation to emphasize the
differences?
