Answer 1

Turns out the form just won't accept periods in the application name. I am unsure why periods are acceptable in the application name within my build then.

Anyway, I will leave this question up here in case someone else runs into this problem because the error message is soooooooo vague.

Answer 2

Just found out a moment ago that creating a client ID for the app in developer console project removes this error and allows the config file to be created...

Developer console projects
APIs & auth
Credentials
Create new client ID:
  Installed application
  Android
  Enter package name
  Enter SHA1 for RELEASE OR DEBUG (which ever one you want it to work with)
  Make deep linking choice
  Create

Then went back to the page and it works. Could be other stuff in the console that you need to do but idk as I already have other stuff set up.
