Without this, your Facebook integration may not work properly when you release your app to the store.

In a previous step, you should have updated your Facebook Developer Settings with the key hashes for your development environments.

When publishing your app, it is typically signed with a different signature to your development environment. Therefore, you want to make sure you create a Release Key Hash and add this to the Android settings for Facebook App ID.

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 OS X, run:

Make sure to use the password that you set when you first created the release key.

This command should generate a 28 characher string. Copy and paste this Release Key Hash into your Facebook App ID's Android settings."/>
