From ee12ae38e4b2631a7341a2299eadc1642b6bca31 Mon Sep 17 00:00:00 2001 From: Emi Griffith Date: Sun, 19 Jul 2026 17:43:56 -0700 Subject: [PATCH] Add Android TWA build config and Digital Asset Links (#203) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Android app is a Trusted Web Activity — a thin native shell that opens the live PWA full-screen in the user's Chrome engine, so it is literally the web app and the existing VAPID web push keeps working inside it via Android notification delegation (no Firebase, no backend change). Adds the build config and the domain-verification file so the app can be built and sideloaded: - deploy/twa/twa-manifest.json — Bubblewrap config; packageId org.thermograph.twa, enableNotifications true (web-push delegation + Android 13 POST_NOTIFICATIONS), colors/icons from manifest.webmanifest. - frontend/.well-known/assetlinks.json — Digital Asset Links, served at the domain root as application/json (verified via the static mount). The signing-key fingerprint is a placeholder until the keystore is generated. - deploy/twa/README.md — build/sideload/verify runbook. Building the signed APK, generating the keystore, filling the fingerprint, and sideloading are local manual steps (documented). Play Store submission is deferred. No backend/ changes.
