Technical Details

App built with MVI architecture.

Presentation layer is done a bit different from classic MVP. There is Model class instance in Presenter, that holds current view state. Presenter does not send any commands to view, instead of this, presenter changes Model properties, and than View render changes. View input events sent to presenter through event method.

Domain layer works much more like MVP + Clean Architecture approach. Business logic is represented by use cases and repositories. Repositories work with data layer and handle entities mapping. Domain layer knows nothing about Android SDK.

Data layer works directly with Android specific tools: network calls, DB queries (In this case app persistent storage made with Realm) and stuff like that.

Tests

You can find unit test here. Current code coverage is about 40%.

Analytics

App has Analytics module, that used to gather user events and record different metrics. There is AnalyticsKit interface, that can be implemented using any of your favorite app metrics tools, like Fabric, Firebase, AppMetrica or whatever. With this approach you can use any number of metrics tools in any combination, and easy add or remove them.

How To Build Project

This app uses News API to retrieve data. You must provide your own api key in order to build the app. Paste it to project gradle.properties in variable named ApiKey.
