5−## Project

6−

7−opencode-android is a native Android client (Kotlin + Jetpack Compose) for the

8−[`opencode serve`](https://opencode.ai/docs/server/) HTTP API. It talks to a

9−remote opencode server over REST plus a long-lived Server-Sent Events stream,

10−and renders conversations (markdown, diffs, tool calls, reasoning, images) with

11−an adaptive single-pane / two-pane Material 3 UI.

12−

13−- Application id / namespace: `soy.iko.opencode`

14−- Package root: `app/src/main/java/soy/iko/opencode`

15−- minSdk 26, compileSdk/targetSdk 35, JDK 17, Kotlin 2.0.x, AGP 8.7.x

16−- Single Gradle module (`:app`); no dynamic feature modules.

17−

18−## Build & environment

19−

20−A Nix flake provides the exact toolchain (JDK 17, Gradle, Android SDK 35, and a

21−Nix-built `aapt2` override because Gradle's bundled aapt2 segfaults on NixOS).

22−

23−```bash

24−nix develop # enter the dev shell (sets ANDROID_HOME, JAVA_HOME, GRADLE_OPTS)

25−./gradlew assembleDebug # -> app/build/outputs/apk/debug/app-debug.apk

26−./gradlew assembleRelease # R8-minified + resource-shrunk; signed only when OPENCODE_STORE_* env vars are set

27−```

28−

29−Outside Nix, you need JDK 17 and the Android SDK (platform 35, build-tools

30−35.0.0) installed manually; `ANDROID_HOME` / `ANDROID_SDK_ROOT` must point at it.

31−

32−Install on a connected device/emulator:

33−

34−```bash

35−adb install -r app/build/outputs/apk/debug/app-debug.apk

36−adb shell am start -n soy.iko.opencode/.MainActivity

37−```

44−./gradlew lintDebug # Android Lint (abortOnError = true)

45−./gradlew connectedAndroidTest # instrumented tests; needs a running AVD or device

46−```

47−

48−- Unit tests live in `app/src/test/...` and run on the JVM. They use fakes from

49− `app/src/test/java/soy/iko/opencode/ui/testing/TestFakes.kt` (Fake* subclasses

50− that override the `open` members of the real stores/clients). JUnit 4 +

51− `kotlinx-coroutines-test`; no Robolectric — `testOptions.unitTests.isReturnDefaultValues = true`

52− stubs Android framework calls so tests brushing `Log.d` etc. don't need it.

53−- Instrumented tests live in `app/src/androidTest/...` and need a device.

54−- detekt runs with a baseline (`app/detekt-baseline.xml`) so only **new**

55− findings block CI; existing ones are grandfathered.

56−- CI (`.github/workflows/build.yml`) runs: `testDebugUnitTest` → `detekt` →

57− `lintDebug` → `assembleDebug` → `assembleRelease`, then uploads both APKs.

88−```

89−

90−Key invariants:

91−

92−- **Subscribe before you prompt.** `SessionRepository.observeMessages` collects

93− the SSE stream *before* the initial REST load and before any prompt POST, so

94− early streamed parts aren't missed. Preserve this ordering if you touch it.

95−- **Resilient decoding.** `OpencodeJson` registers `polymorphicDefaultDeserializer`

96− for `Part`, `BusEvent`, `MessageInfo`, and `ToolState`, so an unknown

97− discriminator decodes to an `Unknown*` / `ToolUnknown` variant instead of

98− throwing. Never add a `when (event)` that isn't exhaustive or that crashes on

99− `UnknownEvent` — the whole point is that a new server release can't break the

100− client. Add new modeled variants alongside the `Unknown` fallback.

101−- **Conflated message stream.** `observeMessages` is `.conflate()`d so a burst of

102− per-token snapshots doesn't back-pressure the reducer. Don't remove this.

103−- **Re-seed on SSE reconnect.** When `EventStreamClient.state` returns to

104− `Connected` after a prior connection, the repository re-fetches messages from

105− REST and merges (without pruning) under a generation counter so a stale fetch

106− can't clobber a newer one. See `SessionRepository.kt` for the contract.

107−- **One Ktor client per profile.** `HttpClientFactory.create(profile)` carries

108− the base URL, JSON negotiation, SSE plugin, and auth. Basic auth is sent

109− eagerly (no 401 challenge round-trip) and only installed for HTTPS profiles;

110− for HTTP profiles the `Authorization` header is set proactively in

111− `defaultRequest` instead, and the reactive Auth plugin is deliberately NOT

112− installed so credentials can't be re-sent silently on a cleartext 401.

113−- **Process lifetime.** `OpencodeApp` installs a `CrashLogger`, builds the

114− `AppContainer`, and registers a JVM shutdown hook (since `onTerminate()` isn't

115− called on real devices) that cancels the app scope and closes the active

116− connection. `AppContainer.shutdown()` is guarded against double-invocation.

139−

140−## Conventions

141−

142−- **No comments unless asked** — existing code has extensive `//` comments

143− explaining *why* (invariants, race conditions, security rationale). When you

144− add code, match that style only for genuinely non-obvious invariants; don't

145− narrate *what* the code does.

146−- **`runCatchingCancellable`** (`util/Coroutines.kt`) instead of `runCatching`

147− inside coroutines — plain `runCatching` swallows `CancellationException` and

148− breaks structured concurrency. Use it for any try/catch in a suspend context.

149−- **`safeExceptionSummary`** for logging Ktor exceptions — `ClientRequestException`

150− messages embed the full request URL (may contain auth/paths); never log the

151− raw exception from an HTTP call. Crash reports scrub URLs via a regex too.

152−- **`open` classes with protected no-arg test constructors.** Stores, the API

153− client, `EventStreamClient`, `OpencodeConnection`, and `AppContainer` are

154− `open` and have a `protected constructor()` so tests can subclass and override

155− individual members without instantiating Android frameworks. Keep this pattern

156− when adding new injectable components.

157−- **`NetworkConfig`** holds all tuning constants (timeouts, backoffs, buffer

158− sizes, layout thresholds, debounce delays). Add new magic numbers here rather

159− than scattering literals.

160−- **REST path encoding.** `OpencodeApiClient` URL-encodes path segments via

161− `encode()` (e.g. `session/${encode(id)}`). Deep-link session ids are validated

162− against `[A-Za-z0-9_-]+` in `MainActivity` to prevent path traversal.

163−- **Idempotency keys.** `sendPrompt` and `runCommand` generate the

164− `Idempotency-Key` header *before* `withRetry` so all retry attempts share it.

165− Preserve this when adding mutating endpoints.

166−- **`withRetry`** wraps all REST reads and the permission response. Transient

167− failures back off with jitter; see `NetworkConfig` for the parameters.

168−- **Compose:** `collectAsStateWithLifecycle` everywhere; `WhileSubscribed` with a

169− 5s grace period (`stateFlowSubscriptionTimeoutMs`). `@Composable` functions

170− use PascalCase (detekt `FunctionNaming` disabled for this reason). Long

171− composables and long parameter lists are accepted (detekt `LongMethod` /

172− `LongParameterList` disabled).

173−- **Manifest:** cleartext HTTP is permitted via `network_security_config.xml`

174− (opencode serves plain `http://`). `enableOnBackInvokedCallback="true"` for

175− Android 14 predictive back. Deep link scheme `opencode://session/{id}`.

176−- **`@Immutable`** on data models exposed to Compose so they skip recomposition

177− correctly.

178−- **Kotlin code style: `official`** (see `gradle.properties`).

179−

180−## Things to avoid

181−

182−- Don't add Hilt/Dagger/KSP — DI is intentionally hand-written (`AppContainer`).

183−- Don't add Robolectric — JVM tests use `isReturnDefaultValues = true` stubs and

184− fakes; only device-dependent code goes in `androidTest`.

185−- Don't run `nix flake check` manually (CI only — per repo convention).

186−- Don't read or query `/nix/store` (extremely large — per repo convention).

187−- Don't introduce new detekt findings; the baseline only grandfathers existing

188− ones. Run `./gradlew detekt` before considering work done.

189−- Don't log raw Ktor/OkHttp exceptions — use `safeExceptionSummary`.

190−- Don't make a `when (BusEvent)` / `when (Part)` non-exhaustive; the `Unknown*`

191− variants exist for forward compatibility and must remain reachable.

192−

193−## Renovate

194−

195−`renovate.json` keeps dependencies current: Kotlin+AGP and Compose are grouped;

196−Ktor is grouped; AndroidX majors are held for manual review (pinned to

197−compileSdk 35). Dependency upgrades land via Renovate PRs, not manual bumps.

37+Crux normally compiles the Rust core to a native library and the shell talks to

38+it over an FFI bridge. That requires an Android cross-compilation toolchain

39+(NDK + a Rust `std` for the `*-linux-android` targets). This project's dev

40+environment intentionally ships **without** an NDK, so instead:

2841

29−The server publishes an OpenAPI 3.1 spec at `http://<hostname>:<port>/doc`.

42+- The **Rust core is the canonical specification** of behaviour and is fully

43+ unit-tested (`cd shared && cargo test`).

44+- The **Android shell runs `OpencodeCore`**, a faithful Kotlin port of the same

45+ reducer, driving an identical `UiState`/`ViewModel`.

3046

31−### 2. (Optional) Add authentication

47+The FFI boundary is kept clean, so the day an NDK is available the Kotlin port

48+can be swapped for the compiled `.so` behind the same seam. The crate already

49+builds as a `cdylib`/`staticlib` and a `codegen` binary is wired for Crux

85−## Install & run

102+Install the APK, launch the app, and enter the server URL (e.g.

103+`http://192.168.1.10:4096`). If the server was started with a password the app

104+detects the `401`, shows credential fields, and connects with HTTP Basic auth.

105+

106+> Cleartext HTTP is enabled so you can reach a `http://` server on your LAN.

107+

108+## The opencode API this client speaks

109+

110+- **Connect / auth** — `GET /global/health` probes reachability; a `401` triggers

111+ HTTP Basic auth.

112+- **Sessions** — `GET /session`, `POST /session`, `DELETE /session/{id}`.

113+- **Messages** — `GET /session/{id}/message` (each item is `{ info, parts }`).

114+- **Send** — `POST /session/{id}/prompt_async` (returns immediately; the reply

115+ streams over SSE).

116+- **Cancel** — `POST /session/{id}/abort`.

117+- **Stream** — `GET /event` (SSE). The client applies `message.updated`,

118+ `message.part.updated` (text/reasoning/tool, with deltas), `message.removed`,

119+ `session.idle` (clears the "generating" state), `session.error`, and

120+ `session.{created,updated,deleted}` incrementally. Unknown event types are

121+ ignored so new server versions don't break the stream.

122+

123+## Continuous integration & releases

124+

125+- **CI** (`.github/workflows/build.yml`) runs on pushes to `master` and PRs: it

126+ unit-tests the Crux core (`cargo test`), runs the Android unit tests + lint,

127+ and builds the debug APK (uploaded as an artifact).

128+- **Releases** (`.github/workflows/release.yml`): push a version tag to cut a

129+ release — it builds a minified, signed release APK and publishes a GitHub

130+ Release with the APK attached and a signed build-provenance attestation.

131+

132+ ```sh

133+ git tag v1.0.0 && git push origin v1.0.0 # or run the workflow manually

134+ ```

135+

136+ The tag name becomes the version (a manual run uses a `YYYY.MM.DD.HHMM`

137+ timestamp), stamped into the APK via `-PversionName/-PversionCode`.

138+

139+ **Signing:** set the repo secrets `OPENCODE_STORE_BASE64` (base64 of your

140+ keystore), `OPENCODE_STORE_PASSWORD`, `OPENCODE_KEY_ALIAS`, and

141+ `OPENCODE_KEY_PASSWORD` to sign with your own key. Without them the release

142+ build falls back to the debug key, so the APK is still installable.

143+

144+## Notes & limitations

145+

146+- Rendering covers text, reasoning, and tool-call parts. Interactive tool

147+ **permission** prompts (`permission.updated`) are not yet surfaced.

148+- Model/agent selection uses the server's configured default (no picker yet).

149+- No `.so` is built in this environment (see *Architecture* above).
