I don't understand why 'onResponse()' is not triggered after successful response?

Question

From the log I can see that the web service correctly returns the JSON to me. But for some reason it never enters the onResponse method.

MainActivity.java

Please add a Log inside onFailure() callback, and just share the Log here in order to figure out the problem. Thanks — MustafaKhaled, Mar 24 '20 at 18:25
Inside the onFailure method add the line 't.printStackTrace()'. That will tell you what's going wrong — Ivan Wooll, Mar 24 '20 at 18:25

I think you are not handling all case correctly like what if onFailure trigger for error.

I am not debugging you project so exact error i can tell you but i suggest you some links where you can find how to debug your code properly.
