Answer 1

Debug SHA-1 certificate fingerprint will be different from production(signed) SHA-1 certificate fingerprint , so you need to set both debug SHA-1 fingerprint and production(signed) keystore SHA-1 fingerprint for same package.

To get Keystore SHA-1 fingerprint you can use following command

keytool -list -v -keystore mystore.keystore 

go to location of your keystore from terminal and replace mystore.keystore with your generated keystore.

Answer 2

you should add api key for both mode debug and release mode as discussed here
