rvlopez / KoTMDb

A kotlin versión for TMDb application.

KoTMDb (Kotlin/The Movie Database)

A very simple application made in Kotlin to improve my skills and learn more about this fantastic language. The application uses the TMDb API and consists of a screen where the most popular movies and series are listed and another where you can see more detailed information of any of them.

The following is a brief description of the technical decisions taken for the development.

Architecture

• Application written in Kotlin based on Clean Architecture for layer abstractions (view/domain/data)
• Model-View-Presenter for the presentation layer
• Interactors / UseCases are used by the presenters to start a data retrieval flow
• UseCases use Repository pattern to request the data needed
• Repository in this case doesn't have DataSources because there's no database/cache/other sources to retrieve data than just * Network. Repository in this project directly request data to the API
• Two different data objects, DTO (Data transfer object) to parse API's response, and Business Object as our own data model.
• DI with Dagger2
• Asynchronous handled by RxJava2 (RxKotlin)
• Image loading handled by Picasso
