Summary

• Used clean-code architecture pattern following modern MVVM(Model-View-ViewModel)

• Heavily inspired by , Google's official android app sample featuring modern architecture and best practices.

• Setup with multiple modules

  • :app
    • The main module where Android App screens, application, fragments, resources, and all other modules were integrated.
    • Ideally, screens could be segregated into multiple sub-modules(i.e. feature modules :feature:trending, :feature:album-details, etc.)
  • :core:model
    • Consists of datamodels used across multiple modules in the project.
  • :core:data

  • :core:network
    • Consist of codes dealing with remote datasources such as REST API(ex. using Retrofit)
  • :core:domain
    • Contains UseCase implementations and may contain additional domain models(i.e. Result classes, etc.) which may be used to address more-specific business use-cases.
  • :core:common
    • Contains utility classes and/or functions that can be used in any modules.

• Dependency Injection using Koin 2.0 (https://insert-koin.io/)

• App Project was constructed following Single Activity App pattern.

  • Using 1 Activity to host NavigationView which manages the entire Navigation Graph.

• Unit Test implementation targeting each *ViewModel classes using test framework.

  • Please see TrendingAlbumListViewModelTest.kt and AlbumDetailsViewModelTest.kt for unit test implementation.
  • (TODO: Provide unit test implementation on data layer and network layer for full coverage)
