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?

Answer 1

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.
