Why can't I deploy to android (Oculus GO)

I seem to get the same two errors, one when I have Gradle activated, another when I do not. I have not been able to find any helpful information about how to get this to work and it seems like there are posts dating back quite some time from people who have had similar issues without any resolution. We are trying to port our PC oculus experience onto our new mobile Oculus GO but have not been able to get the app to deploy straight onto the device or to package into .apk.

A sample of my logs:
