# Matriz de plataformas y funciones

CrossFly es un proyecto **multimódulo Gradle**: la UI y la lógica viven en **`core`** (neutro), y cada
**launcher** (`lwjgl3`, `android`, `ios`, `web`) solo hace el *bootstrap* del SO. El mismo código Java corre
en los cuatro destinos.

## Detección de plataforma
```java
if (Device.platform.isDesktop()) { ... }   // WINDOWS/LINUX/MACOS
if (Device.platform.isMobile()) { ... }     // ANDROID/IPHONE/IPAD
if (Device.platform.isIOS()) { ... }
```
`Platform`: `JAVA` · `WINDOWS` · `LINUX` · `IPHONE` · `ANDROID` · `IPAD` · `MACOS`.

1. La cámara en desktop varía según el SO (ej.: Mac ARM puede devolver `null`).
2. `WKWebView` con `evaluateJavaScript` restringido ([iOS](/docs/platforms/ios)).
3. `createWebView()` devuelve `null` en la web ([Web](/docs/platforms/web-teavm)).
4. `Device.homeFolder` es `null` en la web.
5. HTTP en la web tiene restricciones (CORS, sin sockets) — `Utils.getRemoteFile` devuelve `null`.

> **Regla de oro para la portabilidad:** cualquier recurso de dispositivo puede no existir en un destino. Compruébalo
> antes de usarlo (`Device.platform`, `createWebView() != null`, retorno `null`) — ver
