HELP Video Player App, play the next video at the end


HI, I would like to play the next video in the folder after the first one is finished but I don't know how to do it. I know that I must put something in the OnCompletion() but I don't know how to create the link with the VideoFolder class. I managed to play again the video, like a loop, but I wanna make a loop of the whole folder and idk how to do. If someone can help me...
