Android and the WebView
summary
Recommendation: avoid loading arbitrary remote sites in a WebView and prefer Custom Chrome Tabs for external pages; use WebViewCompat (AndroidX) and WebViewClientCompat to intercept requests, serve local files via AndroidPlatform dot net URLs and the Google local-web-server implementation on GitHub, capture auth redirects in shouldOverrideUrlLoading, disable file access and cache, enable web contents debugging, and use the standard MessageChannel API for bidirectional JS–Android messaging. An EPUB reader built with iframes, injected CSS and these techniques works reliably.
