✨ 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
🗓️ Token Activity	OCGO daily token heatmap (GitHub contribution-graph style): daily / weekly / cumulative views + year switching (last 365 days by default, or a calendar year); personal profile + activity insights (total requests / top 3 request hours) + yearly stats (total / peak / streaks); 6-level pink quantile scale, tap / slide to inspect
📱 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 · Refined Rose primary #C9436C · Blush white background #FDEFF4
🔐 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

# 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

🔧 ARM64 environment notes (optional)

The project bundles an ARM64 AAPT2 binary, which is enabled automatically in ARM64 environments such as Proot/Termux:

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):

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 Management

The project manages all dependencies with a Gradle Version Catalog (gradle/libs.versions.toml).

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
