Bubblewrap TWA config for chat.sune, plus a manually dispatched workflow that builds, signs, verifies against assetlinks.json, attests provenance and publishes the release for the tag given as input. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

Android app
Sune for Android is a Trusted Web Activity wrapper around https://sune.chat, built with Bubblewrap. It contains no app code, only the config in twa-manifest.json.
| New app | Legacy app (v0.x) | |
|---|---|---|
| Package | chat.sune |
com.planetrenox.sune |
| Host | sune.chat (also trusts sune.planetrenox.com) |
sune.planetrenox.com |
| Signing cert SHA-256 | 09:85:1F:7B:BB:40:67:9C:F8:70:1C:7D:9F:65:72:77:78:0E:C0:58:CF:34:09:9A:97:D2:8A:74:FB:CE:87:2A |
E8:7D:70:60:C2:7D:EF:CB:4D:4D:2B:E2:2E:5E:37:ED:F7:0B:1E:F5:77:D7:04:1F:6B:07:EC:B8:1D:78:6D:43 (leaked) |
Both are listed for both domains in public/.well-known/assetlinks.json; that file is what makes Chrome hide the address bar. Remove the legacy entry once nobody uses the old app (a leaked key can sign a fake com.planetrenox.sune that Chrome would trust).
Releasing
Actions → Release APK → Run workflow on master → enter the tag, e.g. v1.0.0.
It builds sune-v1.0.0.apk, signs it, checks the signing cert against assetlinks.json, attests build provenance, then creates the tag and release. versionCode is major*10000 + minor*100 + patch. Run it from any other branch to do a dry run: it builds and verifies but publishes nothing.
Verifying a download
gh attestation verify sune-v1.0.0.apk --repo sune-org/sune
This proves the file was built by this repo's workflow at the commit named in the release, and not modified since. The APK is only a wrapper; the app itself is served live from sune.chat and is not covered by it.
Signing key
Never in the repo (*.jks is gitignored). Repo secrets, read only by .github/workflows/apk.yml:
| Secret | What |
|---|---|
ANDROID_KEYSTORE_B64 |
base64 of the PKCS12 keystore (RSA 4096, alias sune, valid to 2054) |
ANDROID_KEYSTORE_PASS |
keystore password (also used as the key password) |
ANDROID_KEY_ALIAS |
sune |
Losing this key means users can't update chat.sune and would have to uninstall and reinstall. Keep an offline copy.
