	}
}

Architecture

  

The MPV design pattern has been implemented to make views reusable and to isolate business rules from the View layer, which makes it easier to test. The application is divided into three layers, namely View, Presenter, and Data. In addition, there is an interactor responsible to fetch the country information.
