Not able to get any response from callback of Facebook login

Hi,
I am using and following this demo app and guide for integrating Facebook login without Lock.

I am using “AndroidClient” for same. I guess I have configured it properly that’s why it allows me to log in with Facebook. But after login, I am not getting any response.

As per the demo, it should print access-token and tokenId in log, but it is not printing anything. It is also not showing any error dialog or error message.
Can you please look into this and let me know whats wrong happen with this?
