Another Todo List App demonstrates modern Android development practices on Kotlin, utilizing Clean Architecture and the MVVM pattern.
It includes frameworks and features such as: Android Jetpack (Navigation, ViewModel, Room, DataStore) Dagger2, Kotlin Coroutines and Flow, LiveData, Firebase (Authentication, Firestore), along with JUnit 4, Espresso and Mockito for testing.
- Kotlin
- Lifecycle: lifecycle-aware components, which can adjust their behavior based on the current lifecycle state of the activity or fragment
- ViewModel: manages UI's data in a lifecycle-aware fashion. Allows data to survive configuration changes such as screen rotations or light/dark theme switching
- Material Design: provides design components that follow Google's Material Design guidelines such as Bottom Navigation and TextInputLayout
- Databinding: binds UI components in your layouts to data sources in a declarative style
- Coordinatorlayout: enables placement of top-level application widgets, such as AppBarLayout and FloatingActionButton, within your layout
- Recyclerview: displays large sets of data in app's UI while minimizing memory usage, also allows you to use swipe and drag & drop actions by using ItemTouchHelper
- Room: provides an abstraction layer over SQLite to allow fluent database access
- Preferences DataStore: a data storage solution that allows you to store key-value pairs
- Navigation Component: provides support for fragment-based navigation, making a navigation in an app more clear
- Dagger: fully static, compile-time dependency injection framework
- Coroutines: a library for performing asynchronous tasks, managing background tasks in a more efficient and simpler way than traditional methods like threads
- Firebase Firestore: SDK with Kotlin extensions for real-time, cloud-hosted NoSQL database
- Firebase Authentication: SDK with Kotlin extensions for implementing user authentication
- FirebaseUI for Auth: an open-source library that offers simple, customizable UI bindings on top of the core Firebase Auth SDK.
- Testing
- JUnit 4: a fundamental unit testing framework for Java applications
- AndroidX Test: rules for Android testing
- Espresso: a framework for UI testing in Android
- Mockito: a framework for mocking objects in tests, crucial for testing components in isolation
- Robolectric: a framework for unit testing Android code with a simulated Android environment
- Architecture
- Clean Architecture (Presentation - Domain - Data)
- MVVM Pattern (View - DataBinding - ViewModel - Model)
- Repository Pattern
