Answer 1

The problem is due to the Signing Certificate and the SHA-1 certificate fingerprint. Add the following SHA-1 certificates into your googleApi credentials. there are 2 cases

1.If you are running in debug mode add the SHA-1 fingerprint generated by the following

"C:\Program Files\Java\jre1.8.0_101\bin\keytool" -list -v -keystore "%USERPROFILE%\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

2.If you have configured Signing Config then use SHA-1 fingerprint generated by following

"C:\Program Files\Java\jre1.8.0_101\bin\keytool" -list -v -keystore "[youKeyPath]\youKey.jks"

I recommend you to add both the SHA-1 fingerprints in your googleApi credentials
