Technically it should be possible to show ads with WebView (check the ad provider terms).
Is there an example for it?Good question. You can open the external browser with fx.ShowExternalDocument. You need to try to catch the click with the LocationChanged event.
I checked it out , seems pretty cool. I couldn’t find a B4X library for it though.You can try GlobalHop SDK as well. They claim to work in addition to advertising SDK's and can help boost the revenue. Helped me out to build bigger revenue in addition to using ADs.
