thanks in advance..

add below code after declare , initial facebook loginbutton,

your_facebook_loginbutton.setreadpermissions(arrays.aslist("user_location", "user_birthday", "user_likes"));

otherwise, check had add languages information in profile. if user doesn't have data, must null. can see languages information in fb 'about' page -> contact , basic info

hope can you! reference: https://developers.facebook.com/docs/android/graph#userdata
