KotlinMVIDemo

This is a basic project that showcases the use of MVI (Model View Intent) Architecture on Android.

It uses the MovieDB API to retrieve a list of popular movies and the detail of a selected movie.

To run this you need to register on the site and get an API Token, you will add this on the keys.properties file under the app/ folder

Architecture Diagram

Below is a diagram that shows the flow of information on the application.

The classes at the top are the classes used in the flow and the bold ones to the right are the entities used in the flow

The flow of information is as follows:

• The GridFragment class will dispatch a GridEvent object when an action is triggered on the UI
• The GridViewmodel will observe this event using LiveData and will respond to any changes
• When there's a change to the GridEvent LiveData, depending on the event the ViewModel will dispatch an action to the GridRepository to request a resource
• The GridRepository will then return the specified resource as a DataState object
• The ViewModel will relay back this resource to the GridFragment via a DataState observable
• The GridFragment will observe the DataState and react to it, depending on the available resource on the DataState object, the Grid Fragment will dispatch said resource to the ViewModel
• The ViewModel will react to it via a ViewState observable, when any resource is updated the ViewModel will relay back this update to the Grid Fragment via the ViewState observable
• The GridFragment will observe the ViewState and react to it, depending on the available resource it will update the UI Accordingly
