Android Basic Project

Android Basic Project (case: Movie App) built with simple Clean Architecture that connects to TMDB API (themoviedb.org)

• Jetpack Navigation with single Activity
• Coroutines and Flow
• Koin as Dependency Injection
• Room as Persistence storage
• Paging v3 for pagination list
• Retrofit as remote api service
• Mockito (testing)
• Espresso (ui testing)

Globally the project has the following top level packages:

• core : Contains models, repositories and all the related data accessing and manipulating objects.
• di : Dependency module (App Level) provided by Koin
• presentation : Contains Views (Activity, Fragment), Adapter, ViewModel.
• utils : Contains helper extension.

• If there’s new feature with new remote or local data source, create feature package inside presentation package.
• Define new implementation of new Api inside ApiService and RemoteDataSource if any.
• If there's new local data, create new Entity and Dao classes and then define new implementation inside LocalDataSource.
• If there's new Repository, define singleton/factory object inside core/di/CoreModule.
• Create Unit Test inside src/test and instrumented or UI test inside src/androidTest.

• Modularization
• Implement UseCase when the project is more complex
• Better UI TestCase, especially for testing navigation
