Two static files behind nginx and a script that writes them. No authentication: there is no account to check against, and the APK carries no secret — the credential in that app is the addon URL, which lives in the device keystore.

What the `amber-adult` app checks at launch to find a newer build of itself.
|
|
|
|
Two files behind nginx: `manifest.json`, and the APK it names. No
|
|
authentication, deliberately — there is no account to check against and the
|
|
APK holds no secret. The credential in that app is the addon URL, which lives
|
|
in the device keystore and never leaves it.
|
|
|
|
## Publishing a release
|
|
|
|
```
|
|
./release.py ../amber-adult/build/app/outputs/flutter-apk/app-release.apk "what changed"
|
|
```
|
|
|
|
It reads the version and build number out of `amber-adult/pubspec.yaml`, copies
|
|
the APK in under a versioned name, writes `manifest.json`, and commits. Push,
|
|
and Coolify redeploys.
|
|
|
|
**The APKs are committed.** At ~34MB and a handful of releases a year that is
|
|
the cheaper trade against standing up artifact storage for one app; if the
|
|
repository ever gets uncomfortable, the history is disposable — only the
|
|
newest artifact is ever fetched.
|
|
|
|
## The manifest
|
|
|
|
```json
|
|
{
|
|
"version": "0.1.0",
|
|
"buildNumber": 1,
|
|
"notes": "…",
|
|
"sha256": "…64 hex…",
|
|
"size": 34210000,
|
|
"url": "https://media-updates.petruzalekr.cz/media-1.apk"
|
|
}
|
|
```
|
|
|
|
The client refuses anything it cannot act on: an equal or older `buildNumber`,
|
|
a missing `url`, or a `sha256` that is not 64 characters. The download is
|
|
checked against that digest before it reaches the installer.
