The template project that uses Android Architecture Components with Repository pattern. The simple app that uses awesome Fuel library instead of Retrofit for perfoming HTTP request. The app also persists data using the Room library and display data in RecyclerView.

Overview:

Android Architecture Components (AAC) is a collection of libraries that provides lifecycle-aware components for Android development. It offers solutions to problems with configuration changes, data persistence, boilerplate code reduction, memory leak prevention, and simplification of async data loading into the UI. AAC introduces abstractions such as LifecycleOwner, LiveData, and ViewModel to handle the Android lifecycle effectively.

Features:

  • Lifecycle-aware components: AAC provides components that can observe the lifecycle of an Activity or Fragment, allowing UI components to be lifecycle-aware and easily handle configuration changes.
  • LiveData: UI components like TextView or RecyclerView can observe LiveData, which in turn observes the lifecycle of the Activity or Fragment. This simplifies data loading into the UI and helps prevent memory leaks.
  • ViewModel: ViewModel holds state and view data separately from the UI components, ensuring that data is retained during configuration changes and allowing for better separation of concerns.

Summary:

Android Architecture Components (AAC) is a set of libraries that provides developers with tools to simplify and enhance Android development. By introducing lifecycle-aware components, LiveData, and ViewModel, AAC addresses common challenges faced by Android app developers, such as handling configuration changes, managing data persistence, reducing boilerplate code, preventing memory leaks, and simplifying async data loading into the UI. By adopting AAC, developers can create more robust and maintainable Android applications.
