I can't see the background of my Android Wear Emulator

my question is for I can't see the background in my Android Wear emulator, I declare .setBackgroung with a validated image but when I run the App and send me a notification the background does not show.

Any help?

public class NotificationService extends FirebaseMessagingService {
    public static final String TAG = "FIREBASE";
    public static final int NOTIFICATION_ID = 001;
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        //super.onMessageReceived(remoteMessage);
        Log.d(TAG, "From: " + remoteMessage.getFrom());
        Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
        enviarNotificacion(remoteMessage);
    }

    public void enviarNotificacion(RemoteMessage remoteMessage){
        Intent i = new Intent();
        i.setAction("TOQUE_ANIMAL");
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, i, PendingIntent.FLAG_UPDATE_CURRENT);
        Uri sonido = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        NotificationCompat.Action action =
                new NotificationCompat.Action.Builder(R.drawable.ic_full_poke,
                        getString(R.string.texto_accion_toque), pendingIntent)
                .build();

        NotificationCompat.WearableExtender wearableExtender =
                new NotificationCompat.WearableExtender()
                .setHintHideIcon(true)
                .setBackground(BitmapFactory.decodeResource(getResources(),
                        R.drawable.bk_androidwear_notification))
                .setGravity(Gravity.CENTER_VERTICAL);

        NotificationCompat.Builder notificacion = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.notificacion)
                .setContentTitle("Notificacion")
                .setContentText(remoteMessage.getNotification().getBody())
                .setAutoCancel(true)
                .setSound(sonido)
                .setContentIntent(pendingIntent)
                .extend(wearableExtender.addAction(action))
                //.addAction(R.drawable.ic_full_poke, getString(R.string.texto_accion_toque), pendingIntent)
                ;

        NotificationManagerCompat notificationManager =
                NotificationManagerCompat.from(this);
        notificationManager.notify(NOTIFICATION_ID, notificacion.build());
    }
}
