MVC

Ben mentioned that the project is following the MVC pattern, I understand how CurrentWeather and Hourly would both be models, and MainActivity is a controller, but all of the Okhttp code for getting json is in the MainActivity class. Shouldn't this be in a model class?

No, that sort of code shouldn't go into the model class. It is more like a controller. Much like the Activity bind the values in the view to the values of the model, it binds the values retrieved from the API to the model. The API can be considered a different View of data with with the controller acting as the intermediary between the Model and the two different Views. It is possible to separate out the OkHttp code into a new class that handles the API, leaving the Activity with only the UI to be concerned about. But it wouldn't be added to the model, it would be a separate controller.
