Problem with NotificationCompat.MediaStyle() for API Level 26 (Oreo) and beyond

I noticed that the MediaStyle notification isn't working when selecting the compileSdkVersion to 27. As I found in the following link, we must add the following import:
import android.support.v4.media.app.NotificationCompat.MediaStyle;
Additionally, in the showNotification() method, were we set the Style of the builder, we must do it in the following way:
setStyle(new android.support.v4.media.app.NotificationCompat.MediaStyle()

#Edit: it seems that importing the android.support.v4.media.app.NotificationCompat.MediaStyle isn't necessary, so we only have to change the setStyle part.
However, although the notification is shown, the notifications actions are not working.

This won't work in Android 26+ you must create channel
