# برگ وسط — Android (Capacitor) build

The app is packaged with **Capacitor** for Cafe Bazaar / Myket.

## Layout
- `next.config.ts` → `output: "export"` (static site in `out/`)
- `capacitor.config.ts` → appId `com.bargevasat.app`, appName «برگ وسط», webDir `out`
- `android/` → generated native project (committed; build outputs are git-ignored)
- Hardware **back button** handled by `src/components/CapacitorBack.tsx` (`@capacitor/app`)

## Build the web + sync native
```bash
npm run cap:sync          # next build (export) + cap sync android
```

## Build the APK
```bash
npm run android:apk       # → android/app/build/outputs/apk/debug/app-debug.apk
# or open in Android Studio:
npm run android:open
```

> Point the app at the live server at build time:
> `NEXT_PUBLIC_USE_SERVER=1 NEXT_PUBLIC_SERVER_URL=https://api.example.com npm run cap:sync`

## ⚠️ Maven mirror (Iran) — VERIFIED WORKING

Gradle pulls the Android Gradle Plugin from **dl.google.com** + **Maven Central**,
blocked in Iran. The **Myket** mirror proxies both — at the **root** (no `/maven2`):

```
https://maven.myket.ir
```

Copy `android/gradle-mirror.init.gradle.example` → `android/gradle-mirror.init.gradle`,
then build with the init script. (The `gradlew.bat` wrapper has a CLASSPATH quirk on
this setup, so invoke the wrapper jar with `java` directly):

```bash
cd android
java -classpath gradle\wrapper\gradle-wrapper.jar org.gradle.wrapper.GradleWrapperMain \
  assembleDebug --init-script gradle-mirror.init.gradle --no-daemon
# → app/build/outputs/apk/debug/app-debug.apk   (≈4.5 MB)
```

The init script also pins **build-tools 36.0.0** and **Java 17** compatibility,
which are the versions installed here (Capacitor 8 defaults to build-tools 35 / JDK 21).
On a CI box with JDK 21 + build-tools 35 you can drop those overrides.

> For Nexus instead of Myket directly: create a **maven2 (proxy)** repo with
> Remote storage URL `https://maven.myket.ir`, add it to a **maven2 (group)**,
> and point `MIRROR` at the group URL.

## 💳 Payments — ZarinPal (web) vs store billing (Android)

- **Web / PWA**: buying coins uses **ZarinPal** (sandbox now). Flow:
  `POST /api/coins/pay/request` → redirect to `StartPay` → ZarinPal →
  `GET /api/coins/pay/callback` (server verifies + credits) → back to the app
  with `?pay=success`. Merchant id is config-driven (`Zarinpal:MerchantId`,
  swap in the admin panel / appsettings; `Sandbox: true`).
- **Cafe Bazaar / Myket (APK)**: app stores in Iran **require their own
  in-app billing** — do NOT use ZarinPal inside the store build. Use:
  - **Cafe Bazaar**: Poolakey (`ir.cafebazaar.poolakey`) — define in-app products in the Bazaar panel.
  - **Myket**: Myket IAB SDK — define products in the Myket panel.
  Wire a Capacitor plugin that detects the store build and routes `buyCoins`
  to the store SDK; verify the purchase token on the server, then credit coins
  via the same `ProfileService.BuyCoins`. (TODO — needs store accounts + product SKUs.)

## Release (Cafe Bazaar / Myket)
1. Generate a keystore: `keytool -genkey -v -keystore bargevasat.keystore -alias bargevasat -keyalg RSA -keysize 2048 -validity 10000`
2. Configure signing in `android/app/build.gradle` (release `signingConfig`).
3. `gradlew.bat assembleRelease` (or `bundleRelease` for AAB) → upload to Cafe Bazaar / Myket.
4. App icon/splash: replace `android/app/src/main/res/**` (use `@capacitor/assets` to generate).
