Retrofit returns an empty array

I can't get a grasp on Retrofit.. I have an api that returns a result like this: {"user":[{"id":"11","username":"jason95","password":"9355a70301e214efa92b0c5a75be3d29"}]} This is my interface: http://notepad.cc/retrointerface This is my code for the callback: http://notepad.cc/retrocallback If anyone can point me to the correct way to Retrofit, I would GREATLY appreciate it..

By default, Retrofit uses Gson to parse and map the response body from the server to your result object. With the response you're expecting, you need to write a class that maps the JSON object to a Java object. Something like below:

public class ResponseObject {
   User[] user;

   class User {
      String id;
      String username;
      String password;
   }
}

You need to read more about Gson to get that part right. Here's a nice tutorial about using Retrofit with Gson: http://engineering.meetme.com/2014/03/best-practices-for-consuming-apis-on-android/

You could use something other than Gson, but Gson works with Retrofit without any hassle, and will probably fit your needs perfectly.
