Sandbox repository to play around with Android and Kotlin latest goodies.
The News app is a Master / Detail flow app in which the user can search for news and select any news to see its detail.
Note: to compile and being able to search for news you need to get an API key from https://newsapi.org and add it in the gradle.properties file, i.e.: NEWS_API_KEY=“YOUR-API-KEY”
- Search news by a given query
- Offline-first approach
- Offline-first approach, this is, the database is the source of truth.
- Clean architecture layers:
- Layers: the app is organized into the following layers:
- Data layer: provides components to access data from the database and network. DAO and Repository patterns are being used here. Also, the DataModule provides dependencies for all layers using Hilt.
- Domain layer: provides use cases to handle the business logic.
- Presentation layer: provides components to display data on the screen and to handle user interaction.
- Feature package: in the presentation layer the feature packages are:
- searchnews: composable functions and view model to search for news by a given query and then to show the result list of news.
- newsdetail: composable function to show the news detail.
- MVVM architecture pattern with Use Cases.
- Coroutines to execute code asynchronously.
- Flow to push data between layers.
- Jetpack Compose to create UI components in a declarative way.
- Hilt for dependency injection.
- Retrofit for networking.
- Coil for image loading.
- Room for persistence.
- Navigation with go to different screens.
- JUnit, MockK, and Turbine for unit testing.
- All dependencies to libs/tools and third-party libs are in versions.gradle file.
