        @Override
        public void onCancel() {
            // info.setText("Login attempt cancelled.");
            Log.e("In onCancel","oncancel");
        }

        @Override
        public void onError(FacebookException e) {
            //info.setText("Login attempt failed.");
            Log.e("In onError","onerror");
        }
    });

} 

There are no errors. Login screens of facebook are shown.Only new activity is not started. Please help me

Answer 1

You missed the onactivityresult portion. !!!

The problem seems to be with that you are not triggering the callbackManager on onActivityResult after login success. This is the reason why the " onsuccess", " onfailure" or "onerror " methods are not called.

check the below codes. Paste it in your Activity Class

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) 
{
super.onActivityResult(requestCode, resultCode, data);
callbackManager.onActivityResult(requestCode, resultCode, data);
}

Let me know if you have any queries.
