Answer 1

To generate a hash of your release key, run the following command on Mac or Windows substituting your release key alias and the path to your keystore.

On Windows, use:

keytool -exportcert -alias  -keystore  | openssl sha1 -binary | openssl base64

This command should generate a 28 characher string. Remember that COPY and PASTE this Release Key Hash into your Facebook App ID's Android settings.
