This is the issue: When I run my app which is using Google Play Game Services I got an error trying to sign in "The application is incorrectly configured. Check that the package name and sign in certificate match the client ID created in Developer Console".
I checked the suggested and everything look OK, but reading the Logcat I noted the SHA1 fingerprint is not the same of my .keystore file. It's a little confused because when I execute the keytool command to view the .keystore file information, I can see the same SHA1 that is related with my app id in the Developer Console.
Thanks a lot for your help.
