Sorry, you just can't re-use a WebView across config changes -- a view is instantiated with a Context it runs in, which is the Activity that created it. You can't change this context later, when you have a new Activity instance.
I have a WebView in my Activity which I want to reuse across config
changes so that the webpage does not get reloaded after every
orientation change. I can use
for this. However, I have heard that Fragment#setRetainInstance is
better for this purpose. This does not seem correct if there are other
Views involved which should be recreated after a config change (eg.
TextView which should be recreated after a locale change so that new
string resources can be picked up). I could keep only the WebView in a
Fragment, and all other Views in the Activity, but then either
approach seems good enough.
Note: please don't send private questions to me, as I don't have time to provide private support, and so won't reply to such e-mails. All such questions should be posted on public forums, where I and others can see and answer them.
