Failed to build apk???

CommandInvokationFailure: Failed to build apk.

Yup, that’s the error I get when I try and do a build for android, I have tried following dozens of tutorials, all of which are convoluted and only get you so far, some say take this file or that file and move it here or move it there or down load this version of JDK and so on and so on and so on… feels like I’ve been going around in circles trying to get set up for doing an android build with no end in sight.!!
I’m running Unity 5.6.3f1 on Windows 10 for what that’s worth.

PLEASE Help I’m at my whit’s end with the stupidity of how difficult this is to get just simply set up!!

I remember getting something like that. Have you tried reinstalling Unity, that’s what I did. I would also suggest upgrading your version of Unity. If you reinstall Unity, you’ll be asked what kind of builds you want to build to like; Windows, Mac, Facebook Game room, and Android. It will automatically download the correct files that you will need for building to those platforms.
