Solution 1:

Quote from FB developers site

To authenticate the exchange of information between your app and the Facebook, you need to generate a release key hash and add this to the Android settings within your Facebook App ID. 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:

keytool -exportcert -alias <RELEASE_KEY_ALIAS> -keystore <RELEASE_KEY_PATH> | openssl sha1 -binary | openssl base64

On Windows, use:

keytool -exportcert -alias <RELEASE_KEY_ALIAS> -keystore <RELEASE_KEY_PATH> | openssl sha1 -binary | openssl base64
