how do you make android automatically start a media player and...

I'm looking to see if i can make a cheap no-touch bootable android stick to put on a tv in my office to play some randomized videos. I just need it to continue indefinitely. But i dont want anyone to have to touch it as i dont want anyone to need start do anything other than power it on to start it.

Thanks

Find a startup or boot manager app (there are a few) and add the video player to it. Set the video player to continually play a playlist (some can, some can't).
