Android APK blank screen: no Gatekeeper URL in production build

[macterra]

Problem

The GitHub Actions release workflow (android-debug-build-release.yml) builds the APK with vite build --mode production, but there is no .env.production file committed — only .env.production.example. This means VITE_GATEKEEPER_URL is undefined in the built APK.

On a physical device, the app can't reach any Gatekeeper and renders a blank screen. (.env.android uses 10.0.2.2 which only works in the Android emulator.)

Options

1. Commit a .env.production with a default public Gatekeeper URL (e.g. https://4tress.org)
2. Use GitHub Actions secrets to inject VITE_GATEKEEPER_URL at build time
3. Change android:build to use --mode android and update .env.android with a public URL
4. Add a settings screen in the app so users can configure the Gatekeeper URL at runtime
