On-device, the native SSO buttons never appeared and the flow dumped users on
the desktop website login (which can't deep-link a mobile session back), so it
hung. Two app-side causes:
1. Discovery conflated "no providers" with "call failed" (ssoProviders() returned
emptyList() on any error) and the screen then showed a dead website-login
hand-off. Now ssoProviders() returns Available/None/Unavailable, retries once,
and the login screen renders native provider buttons, a loading hint, or a
retry — never the website login fallback (removed, along with WebsiteUrls.login).
2. The pending {state, verifier} lived only in memory, so a Custom-Tab-induced
process eviction lost it and the exchange failed STATE_MISMATCH. Persist it via
a new encrypted PendingSsoStore (EncryptedSharedPreferences, mirrors the token
store), cleared the moment the callback is consumed so replays still fail closed.
SsoAuthManager stays framework-free (store behind an interface). +1 test proving a
fresh manager on the persisted store completes (process-death sim); 15/15 SSO tests
pass, lint + assembleDebug green (JDK21, -Pksp.incremental=false).
Verified end-to-end against the local site via the dev stub IdP: player and admin
both sign in natively and receive the correct role.

Runic Gateway — Android app
A native Android client for a Runic Gateway shard's public site + player self-service. It is
purely an API client of the website backend — it never talks to the link/ sidecar or the game
shard directly, and it ships none of the shard/sidecar wiring. It surfaces the same content and
player features as the website's browser client, minus every administrative/management console.
The authoritative design contract is docs/android/PLAN.md
in the RunicGateway/docs repo. The authoritative API reference is the committed OpenAPI spec at
website/server/swagger/swagger-output.json.
Status
M0 — repo scaffold. Gradle + Compose + Hilt skeleton with CI (lint + unit test + debug build). The functional Kotlin pass (M1–M4) and the design pass (M5) follow — see the plan's milestones (§9).
Stack
| Concern | Choice |
|---|---|
| Language / UI | Kotlin + Jetpack Compose (Material 3) |
| Navigation | Navigation-Compose, single-activity |
| HTTP | Retrofit + OkHttp, kotlinx.serialization |
| Async | Coroutines + Flow |
| DI | Hilt |
| Prefs / base URL | Jetpack DataStore |
| Tokens at rest | EncryptedSharedPreferences |
| Images | Coil |
| Min SDK | Android 10 (API 29) |
| Target / compile SDK | 35 |
Dependency and plugin versions are pinned in gradle/libs.versions.toml.
Build
Requires JDK 17 and the Android SDK (ANDROID_HOME / local.properties).
./gradlew assembleDebug # build a debug APK -> app/build/outputs/apk/debug/
./gradlew test # JVM unit tests
./gradlew lint # Android lint
./gradlew installDebug # install on a connected device/emulator
The app self-configures its server URL on first run (PLAN.md §3), so a single build works against any shard's website — there is no compiled-in API host.
CI
.gitea/workflows/pr-checks.yml gates PRs into main with ./gradlew lint test assembleDebug on the
org's self-hosted runner (JDK 17 + Android SDK). Debug builds are auto-signed, so the gate needs no
secrets. This pipeline is verified green end-to-end on the runner (M0). A signed release APK
attached to a Gitea release comes at M6.
The workflow carries a few runner-specific accommodations (each explained in comments in the file), because this self-hosted runner differs from a stock GitHub runner:
- JDK 17 is installed via
apt(notactions/setup-java) — the runner can't resolveapi.adoptium.net, while the Ubuntu mirrors are reachable. - SDK packages are installed explicitly via
sdkmanager, withset +o pipefailsoyesdying ofSIGPIPEdoesn't fail the step. gradlewischmod +x'd in the run step — the runner's checkout does not preserve the git executable bit, so./gradlewalone fails with "Permission denied".
