Sorry for the confusion. I do that a lot. I have an Android. When I saw 'Ki' in the thread I didn't read it. I confused 'Kindle' with 'KitKat'.
I hit a wall with the changing folders without rooting. I got to a point beyond my limited expertise. I am going to try rooting the device and hope I don't do anything too damaging.
P.S. If you're interested the You Tube link is

It uses the official Android Studio.
