onResponse/onFailure

if we can handle the case, when the response is not succeessful, in the onResponse method, what situations can cause the onFailure method to be called? I can't understand why we need it.

Hey Sergey there are many cases where the on failure would be called for example if the server is down completly and you make a web call to retrieve some data. Then you need to know that your request failed to alert the user that there was some issue getting there data. Here are some other examples of something that would make the web call fail.

Connection time out. Session time out. Data integrety (XML) Authentication
