MovieStubs

MovieStubs is an app for users to discover and research movies. In addition, users can also purchase a movie ticket from the app. For the purpose of the assignment, I focused most of my time on the app architecture instead of the UI/UX

Features

• Movie Discovery - view top 10 or all movies of the year at a glance
• Movie Research - view details of a movie (duration, actors, poster, description)
• Movie Booking - purchase a ticket for the movie

App Architecture

Separation of concerns

• Business logic should not be intertwined with the UI code
• UI-based classes should only contain logic that handles UI and operating system interactions

Drive UI from a model

• The (view) model is responsible for handling data for the UI
• The (view) model should not be affected by the app's lifecycle and configuration changes

Repository Pattern (https://martinfowler.com/eaaCatalog/repository.html)

• Repositories to be mediators between different data sources
• A repository pattern approach will provide a clean API to retrieve data easily from single or multiple access points. (network, local storage, etc..)

Libraries

• Live Data & view model - android life cycle
• Navigation
• Retrofit - API HTTP client
• Gson - serialization/deserialization of Java/Kotlin objects to JSON
• Glide - image loading & caching
• Hilt (dagger) - for dependency injection https://developer.android.com/training/dependency-injection
• Data & View binding - to reduce UI & layout boilerplate
