Q: What is the problem of above approach ?
A: You activity has a lot of scattered code for Facebook login, It will be more complex and unmanageable when you will have another social network login like Facebook and Twitter.
Q: How I will receive a response for login success?
A: You need to implement interface "FacebookLoginStatus", on successful login you will receive callback "OnSuccessFacebookLogin"
Q: What will be received on login success ?
A: You will have Name, Email , First Name, Last Name, User Id.
Q: Do I need to handle login failure / error ?
A: No, FacebookLoginUtils.java will handle login failure, error and display appropriate message on screen.
