}

I can se the preview and when I click it become full screen but it’n not working.
imageCapture is not null and there are two cameras available

val availableCameras = cameraProvider.availableCameraInfos

if (availableCameras.isEmpty()) {
    Log.e("CameraX", "Nessuna fotocamera disponibile sul dispositivo.")
    return // O gestisci l'errore in modo appropriato
}

// Log delle informazioni sulle fotocamere disponibili per il debugging
availableCameras.forEach { cameraInfo ->
    Log.d("CameraX", "Camera disponibile: ${cameraInfo.cameraSelector}")
}
