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+```
38+
39+## Test, lint, and static analysis

41+```bash
42+./gradlew testDebugUnitTest # JVM unit tests (JSON/reducer/ViewModel logic)
43+./gradlew detekt # static analysis; config: config/detekt/detekt.yml, baseline: app/detekt-baseline.xml
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.

67+(`OPENCODE_SERVER_PASSWORD`; username defaults to `opencode`). See the README's
68+"Set up a server and connect to it" section for full details.
69+
70+## Architecture
71+
72+Unidirectional data flow with manual DI, no annotation processing (no Hilt/KSP).
73+
74+```
75+OpencodeApp (Application)
76+ └─ AppContainer (service locator: profile/settings/draft stores, active connection,
77+ unread tracker, auto-reconnect, pending share / open-session signals)
78+ └─ OpencodeConnection (one per active server profile)
79+ ├─ HttpClient (Ktor + OkHttp, base URL + Basic auth + JSON + SSE)
80+ ├─ OpencodeApiClient (REST: sessions, messages, files, providers, agents, commands, permissions)
81+ ├─ EventStreamClient (long-lived GET /event SSE -> hot SharedFlow<BusEvent>)
82+ └─ SessionRepository (reduces BusEvents + REST seeds -> Flow<List<MessageWithParts>>)

84+
85+ViewModels (ui/<feature>/<Feature>ViewModel.kt)
86+ └─ expose StateFlow; Compose collects with collectAsStateWithLifecycle
87+ └─ built via ui/VmFactory.kt (viewModelFactory { initializer { ... } }) from the AppContainer
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.

35−### Why a Kotlin port instead of a JNI `.so`?
36−
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:
41−
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`.
46−
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
50−type-generation.

68−## Getting started
9+This app is a client for the [`opencode serve`](https://opencode.ai/docs/server/) HTTP API, so you
10+need an opencode server running somewhere reachable from your device.
6911
70−### Dev shell
12+### 1. Start the server
7113
72−Everything you need is provided by the Nix flake:
14+On the host that has your project and opencode installed:
7315
74−```sh
75−nix develop # or: direnv allow (an .envrc with `use flake` is included)
16+```bash
17+opencode serve --hostname 0.0.0.0 --port 4096
7618```
7719
78−This puts JDK 17, Gradle, `rustc`/`cargo`, and the Android SDK (platform 35,
79−build-tools 35.0.0) on your `PATH`.
20+Useful flags:
8021
81−### Build & test
22+| Flag | Default | Description |
23+| --- | --- | --- |
24+| `--port` | `4096` | Port to listen on |
25+| `--hostname` | `127.0.0.1` | Hostname/interface to bind (`0.0.0.0` exposes it on your LAN) |
26+| `--mdns` | `false` | Enable mDNS discovery |
27+| `--cors` | `[]` | Extra browser origins to allow (repeatable) |
8228
83−```sh
84−# Rust core — logic + streaming unit tests
85−cd shared && cargo test
86−
87−# Android app — debug APK
88−./gradlew assembleDebug # -> app/build/outputs/apk/debug/app-debug.apk
89−
90−# Android unit tests + lint
91−./gradlew testDebugUnitTest lintDebug
92−```
29+The server publishes an OpenAPI 3.1 spec at `http://<hostname>:<port>/doc`.
9330
94−### Run against a server
31+### 2. (Optional) Add authentication
9532
96−Start opencode's server on your machine or LAN:
33+opencode has no auth by default. To protect the server with HTTP Basic auth:
9734
98−```sh
99−opencode serve --port 4096 # optionally behind OPENCODE_SERVER_PASSWORD
35+```bash
36+OPENCODE_SERVER_PASSWORD=your-password opencode serve --hostname 0.0.0.0 --port 4096
10037```
10138
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.
39+The username defaults to `opencode` (override with `OPENCODE_SERVER_USERNAME`). Enter these in the
40+app's add-server dialog.
10541
106−> Cleartext HTTP is enabled so you can reach a `http://` server on your LAN.
42+### 3. Connect from the app
10743
108−## The opencode API this client speaks
44+**Over Wi-Fi / LAN** — add a server with base URL `http://<host-LAN-ip>:4096`.
10945
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.
46+**Over USB only** — forward the port to the device and point the app at localhost:
12247
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− ```
48+```bash
49+adb reverse tcp:4096 tcp:4096
50+```
13551
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`.
52+Then use base URL `http://127.0.0.1:4096` in the app.
13853
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.
54+> The app permits cleartext HTTP because opencode serves plain `http://`. If you terminate TLS with
55+> a reverse proxy, use an `https://` base URL instead.
14356
144−## Notes & limitations
57+## Architecture
14558
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).
59+- **Ktor 3 (OkHttp engine)** for REST + the long-lived `GET /event` SSE stream.
60+- **kotlinx.serialization** with sealed polymorphism for opencode's discriminated unions
61+ (`Part`/`type`, `MessageInfo`/`role`, `ToolState`/`status`, `BusEvent`/`type`). Unknown
62+ discriminator values fall back to `Unknown*` variants (`OpencodeJson`) so a new server release
63+ can't break decoding.
64+- **Manual DI** (`AppContainer` on the `Application`) — no Hilt/KSP.
65+- **Unidirectional state**: `EventStreamClient` exposes the SSE stream as a hot `SharedFlow`;
66+ `SessionRepository` reduces events into per-session message state; ViewModels expose `StateFlow`;
67+ Compose collects with `collectAsStateWithLifecycle`.
68+- The repository subscribes to `/event` **before** the prompt POST so no early streamed part is missed.
69+
70+Source map: `data/network` (Ktor, SSE, JSON), `data/model` (wire models), `data/repo`
71+(reducer + profile persistence), `di` (container/connection), `ui/<feature>` (Compose screens).

52+ * Renders markdown using [multiplatform-markdown-renderer](https://github.com/mikepenz/multiplatform-markdown-renderer)
53+ * (commonmark-java under the hood). Keeps a local API so callers don't import the library directly.
54+ * Long-press copies the raw markdown to the system clipboard. Code blocks/fences get an
55+ * inline copy button.
56+ *
57+ * During streaming, the full markdown is re-parsed on every token (the library re-parses
58+ * whenever the content string changes). To avoid O(n²) work during long responses, the
59+ * rendered content is throttled — the latest [markdown] is committed to the renderer at
60+ * most once every ~50ms, so a burst of tokens coalesces into a single re-parse.
61+ *
62+ * The throttle uses a single long-lived `LaunchedEffect(Unit)` that observes the markdown
63+ * parameter via `rememberUpdatedState` + `snapshotFlow` + `conflate` + `collect`. A keyed
64+ * effect (`LaunchedEffect(markdown)`) cancels and restarts on every token; if tokens arrive
65+ * faster than the throttle delay, the in-flight `delay` is cancelled before it completes,
66+ * starving the render and showing stale content until the stream pauses. The conflated
67+ * `collect` lets the delay run to completion, then picks up the most recent buffered value,
68+ * so rendering always progresses even under continuous fast streaming.
69+ *
70+ * When [streaming] is false (the common case: every non-active message in the chat list),
71+ * the throttle pipeline is skipped entirely — no `LaunchedEffect`, no `snapshotFlow`, no
72+ * coroutine. This eliminates per-item coroutine churn as messages scroll in and out of view.
