Helium Mobile Wrapper (Android)

This is a TypeScript mobile wrapper built with React + Capacitor for opening the Helium web app on Android.

Why this approach

• Capacitor keeps the project in TypeScript.
• The app opens Helium in a Chrome Custom Tab, which is currently the most reliable way to get Android WebRTC features (including screen audio when the device supports it).

Setup

pnpm -C mobile-wrapper install
pnpm -C mobile-wrapper build
pnpm -C mobile-wrapper cap:android:add
pnpm -C mobile-wrapper cap:sync
pnpm -C mobile-wrapper cap:android:open

Then build/run from Android Studio.

Notes on screen sharing with audio

• Android support for screen-capture audio depends on OS version, Chrome version, OEM restrictions, and user permissions.
• If audio is unavailable, update Android + Chrome and confirm audio capture is enabled in the system screen-share dialog.
• A pure in-app WebView wrapper is less reliable for audio capture than Chrome Custom Tabs on Android.
