A modern Pokedex Android app based on development with Hilt, Coroutines, Flow, Jetpack (Room, ViewModel), and Material Design using MVVM architecture.
- Minimum SDK level 24
- Kotlin based, Coroutines + Flow for asynchronous.
- Jetpack
- Lifecycle: Observe Android lifecycles and handle UI states upon the lifecycle changes.
- ViewModel: Manages UI-related data holder and lifecycle aware. Allows data to survive configuration changes such as screen rotations.
- Room: Constructs Database by providing an abstraction layer over SQLite to allow fluent database access.
- Hilt: for dependency injection.
- Architecture
- MVVM Architecture (View - ViewModel - Model)
- Repository Pattern
- Retrofit2: Construct the REST APIs and paging network data.
- ksp: Kotlin Symbol Processing API.
- Material-Components: Material design components for building ripple animation, and CardView.
Pokedex is based on the MVVM architecture and the Repository pattern, which follows the Google's official architecture guidance.
The overall architecture of Pokedex is composed of two layers; the UI layer and the data layer. Each layer has dedicated components and they have each different responsibilities, as defined below:
The UI layer consists of UI elements to configure screens that could interact with users and ViewModel that holds app states and restores data when configuration changes.
The data Layer consists of repositories, which include business logic, such as querying data from the local database and requesting remote data from the network. It is implemented as an offline-first source of business logic and follows the single source of truth principle.
Pokedex is an offline-first app is an app that is able to perform all, or a critical subset of its core functionality without access to the internet. So users don't need to be up-to-date on the network resources every time and it will decrease users' data consumption. For further information, you can check out Build an offline-first app.
