Cache a Progressive Web App inside a WebView

Question

I've got a Progressive web app and packaged inside an android WebView. I'd like it to work offline. How do I access the cache/service worker and make it happen?

This is simple - use the ServiceWorkerController instance. Although it only works on Android N and up so make sure to tell your users to install your site as a PWA for these users.

Thanks for the link, but how do I use the instance specifically? I'm not really sure about that, the docs don't really tell me how.

stackoverflow.com/questions/45773104/… shows an example and explains how it works so that should work fine for you.
