Description

This is a sample project with the main objective of integrating Jetpack components as much as possible in a single app.
Additionally, the project try to implement ideas from Domain-Drive Design, Design Patterns, and Clean Architecture mainly focused on the Dependency Inversion principle.

The app topic is Movies and you may find functionalities such as:

• search movies by name.
• see the movie extra details.
• mark the movie as favorite.
• listing favorite movies.

Domain Model

The Domain Model pattern is shown here in a very simple way.
This project is trying to follow the ideas explained in Domain-Driven Design book of Eric Evans.
Yet, there are only a few entities, so far, such as: Movie and TomatoMeter.

Architecture

It's strongly recommended to read Clean Architecture book of Robert C. Martin for a better understanding and avoiding misconceptions out there.
As a glimpse, read Clean Code blog: https://blog.cleancoder.com/uncle-bob/2012/08/13/the-clean-architecture.html
