Your response body is null. – K Neeraj Lal Aug 06 '18 at 05:24
response.body() may be null or contains the response which is not the match with the User model. – Sunny Aug 06 '18 at 05:28
add user.getError_msg()!=null in your if condition – Akash Pal Aug 06 '18 at 05:34
Did not work at all... – Sawrozz Aug 06 '18 at 11:41
