## ✨ Features
| Feature | Description |
|------|------|
| 📊 **Dashboard** | DeepSeek balance (¥) + usage/balance cards for each service; OCGO/CCGO cards link directly to usage details; long-press & drag to reorder (persisted); pull-to-refresh globally · tablet-adaptive two-pane layout |
| 📈 **Usage charts** | 3 Canvas-drawn charts — amount spent / API request count / token consumption (dual data sources: OCGO & CCGO); UTC+0/UTC+8 timezone switching and custom day/month/range; automatic fallback (no data in last 5h → 12h → 7 days → current month); side-by-side on tablets |
| 📱 **Tablet adaptation** | Global `BoxWithConstraints` adaptive container width; ≥600dp dual-column cards, ≥700dp side-by-side charts; two-pane 35/65 split (Expanded mode); supports Android 13+ predictive back gestures |
| 📋 **Detailed data** | Paginated browsing of raw records with time + model filtering; tap to view full fields |
| 🔍 **Multi-granularity filters** | 5 hours / 12 hours (10-minute buckets) / 24 hours / today / yesterday / last 7 days / last 30 days / current month / custom day · month · range |
| 🏷️ **Model filtering** | Multi-select / single-select / select all, with dynamic legends that wrap automatically |
| 📱 **Home screen widget** | Check usage without opening the app; switch between four services (OCGO/CCGO/Codex/Ollama) + DeepSeek balance; top-left corner → open app, tap elsewhere to switch, ↻ to refresh; can be added to the At a Glance screen; auto-refreshes when scrolled into view (MIUI exposure refresh) |
| 🔄 **Auto sync** | Pull-to-refresh on home auto-syncs usage; auto full sync on startup when no cache; CCGO detail page supports manual clear & re-sync |
| 🌙 **Dark mode** | Fully adaptive — in-app text/icons/background switch automatically; widget adapts independently with a dark layout |
| ➕ **One-tap add to home screen** | Tap + inside the app to add the widget directly, no need to browse the system list; double confirmation + permission check |
| 💡 **Usage tips** | Home page shows a random operation tip (refreshed on each launch); settings page lists all 13 hidden tips |
| ⚡ **Room database** | Usage records stored in Room (indexed on workspaceId+timeCreated); DAO queries replace full JSON serialization; auto-migration from the legacy DataStore on first launch |
| 🎀 **Rainy pink theme** | Material Design 3 · Strawberry Pink #FF85A2 · Sakura Pink #FFD1DC |
| 🔐 **Codex OAuth sign-in** | Headless OAuth PKCE: the app generates an authorization link → sign in in an external browser → paste the callback URL to complete authorization; no manual auth.json export needed |
| ⚡ **Codex one-tap usage activation** | Codex detail page can send a short request to the ChatGPT API to trigger usage tracking; model list fetched dynamically from models.dev and persisted, with manual refresh; response dialog is copyable |
| ⚡ **OCGO / Ollama one-tap usage activation** | OCGO detail page can send a request to `opencode.ai/zen/v1`, Ollama detail page to `ollama.com/v1` to trigger usage tracking; API keys are entered manually in settings; model lists fetched dynamically from models.dev |
| 🐛 **Debug logs** | In-app "Debug Logs" page showing detailed logs of Repository network requests, token refreshes, parse errors, etc.; no computer needed |
| 🌐 **Multilingual** | Simplified Chinese / 繁體中文 / English interface; one-tap switching in settings (follow system / Simplified / Traditional / English); two-way sync with the system "App languages" page on Android 13+; non-CN/EN system languages fall back to English; home screen app name and widget follow the language |

## 🛠️ Build
### Option 1: Android Studio (recommended)
1. Clone the repository: `git clone https://github.com/CATMIAOZHI/Rainytoken.git`
2. Open the project in Android Studio
3. Sync Gradle, connect a device, and hit Run ▶️
### Option 2: Command line
```bash
# Run unit tests
./gradlew testDebugUnitTest
# Build a Debug APK
./gradlew assembleDebug
# APK output: app/build/outputs/apk/debug/app-debug.apk
# Build a Release APK
./gradlew assembleRelease
```
<details>
<summary>🔧 ARM64 environment notes (optional)</summary>
The project bundles an ARM64 AAPT2 binary, which is enabled automatically in ARM64 environments such as Proot/Termux:
```bash
chmod +x ./setup_android_env.sh
./setup_android_env.sh
```
The script configures `$ANDROID_HOME` and uses the project-bundled ARM64 build-tools.
**Extra Release build configuration**: Under ARM64 Proot, AGP 9.0 passes `--resource-path-shortening-map=<path>` (equals-sign syntax) to `optimizeReleaseResources`, which the ARM64 AAPT2 does not accept. Configure the AAPT2 wrapper in `~/.gradle/gradle.properties` (global, not committed to the repository):
```properties
android.aapt2FromMavenOverride=/path/to/android-aapt2-wrapper/aapt2
```
The wrapper script splits the equals-sign syntax into two separate space-delimited argv entries. The project's `build.gradle.kts` includes a built-in `guardReleaseResources` task as a build safeguard (falls back to the linked `.ap_` automatically when the optimized `.ap_` is missing).
> On x86_64 environments (GitHub Actions / regular Linux), the official AAPT2 is used automatically — no extra steps required.

| Dependency | Purpose |
|------|------|
| `androidx.compose:compose-bom` | Jetpack Compose BOM |
| `androidx.navigation:navigation-compose` | Page navigation |
| `com.squareup.retrofit2:retrofit` | DeepSeek REST API |
| `com.squareup.okhttp3:okhttp` | OpenCode Go web scraping |
| `org.jetbrains.kotlinx:kotlinx-serialization-json` | JSON serialization |
| `androidx.room:room-runtime` | Local usage database (Room) |
| `androidx.datastore:datastore-preferences` | Local caching |
| `com.google.dagger:hilt-android` | Dependency injection |
| `com.google.devtools.ksp:symbol-processing-api` | KSP annotation processing |

## 🔒 Security
- ✅ API keys / session credentials are stored in the **Android Keystore** (AES-256 GCM encrypted)
- ✅ Network requests are only sent to the official DeepSeek / OpenCode APIs
- ✅ `allowBackup=false`: encrypted credentials and usage data are excluded from system backups, preventing undecryptable ciphertext when restoring on a new device
- ✅ Fixed signing key — every Release can be installed over the previous version
- ✅ Signing keys and passwords are stored encrypted in GitHub Secrets and decrypted during CI
