OK...this was not wonderfully easy, but I figured it out. It all came down to the Certificate Fingerprints (SHA-1)...I needed to get a program called keystore explorer to open the keystore file from the basic4android install path and use that instead of the key that I got using the keytool as they were different. Once I did this the login button went on to prompt if I wished to allow the app to access after selecting the account.
