Hyperview probably isn’t the best fit for apps with deep platform integration. Given that it’s designed to be cross-platform and server-rendered, I think this use case would be better served writing code directly against the Android SDK.

Looks like you have do that via React Native components: https://hyperview.org/docs/reference_custom_behaviors

It does seem imaginable to have Android-specific browsers support a common superset of the "nominal/desktop" browser js api. Reference to Hyperview not specifically required, but an enabler for such.

Security issues of course, so specific pages/sites might need permissions, as with webserial etc.
