Sección titulada “Consejos para seguir”1. Elige el método de transferencia adecuado
Sección titulada “1. Elige el método de transferencia adecuado”| Método | Uso de caso | Entrega |
|---|---|---|
sendMessage | Interactivo, sensible a la hora | Inmediato (falla si no se puede alcanzar) |
updateApplicationContext | Estado de la aplicación actual | Último valor disponible |
transferUserInfo | Datos importantes | Programado, garantizado |
2. Maneja la inactividad en línea con gracia
Sección titulada “2. Manejar con Gracia la Oficina”async function smartSend(data: any, important: boolean) { const info = await CapgoWatch.getInfo();
if (info.isReachable) { // Send immediately await CapgoWatch.sendMessage({ data }); } else if (important) { // Queue for later await CapgoWatch.transferUserInfo({ userInfo: data }); } else { // Update context (will be available when watch opens app) await CapgoWatch.updateApplicationContext({ context: data }); }}3. Minimizar el Tamaño de Datos
Sección titulada “3. Minimizar el Tamaño de Datos”// Bad - sending large objectsconnector.sendMessage(["user": fullUserObject])
// Good - send only what's neededconnector.sendMessage([ "userId": user.id, "name": user.displayName, "avatarUrl": user.avatarUrl])4. Usar Haptics de Forma Apropriada
