Android relies on WebView for rendering web pages inside apps – the pages you see inside a lot of apps that require user inputs. Login screens are a typical example of this implementation and it is highly likely that you would have come across one if you’ve been using an Android smartphone. Ever since Android 5 Lollipop, WebView became a separate component and from Android 7 Nougat, Chrome started handling it which will be changing again on Android 10.

“Like with Monochrome, users can find each of these four channels of WebView on the Play Store and install them simultaneously on a single device. Also like Monochrome, users can use the “WebView implementation” menu to choose which installed WebView the system should use.”, reads the Chromium project page.
