What are some examples of Android Architecture Components?

Android Architecture Components are a collection of libraries that help you design robust, testable, and maintainable apps. Examples include LiveData, ViewModel, Room, and Data Binding.

Can you explain how LiveData works?

LiveData is an observable data holder class that allows UI components to observe changes in data. It ensures that UI updates only occur when the component is in an active lifecycle state.

What is the purpose of ViewModel?

ViewModel is designed to store and manage UI-related data in a lifecycle-conscious way. It survives configuration changes like screen rotations.

How does Room database fit into this architecture?

Room provides an abstraction layer over SQLite, allowing for more robust database access while leveraging the full power of SQLite.

Can you give an example of using Data Binding?

Data Binding allows you to bind UI components in your layouts to data sources in your app using a declarative format. For example, you can bind a TextView to a LiveData object to automatically update the UI when the data changes.
