Explain the role of the Android OS in the architecture.
The Android OS manages hardware resources, provides a user interface, and supports application development in the architecture.
The Android OS does not interact with hardware components.
The Android OS is solely responsible for network connectivity.
The Android OS only provides security features for applications.
What is the purpose of the Android Runtime (ART)?
To provide a user interface for Android apps.
To manage device hardware resources.
The purpose of the Android Runtime (ART) is to execute Android applications efficiently.
To store application data permanently.
Describe the function of the Application Framework in Android.
It manages hardware resources directly.
It is responsible for the Android operating system updates.
It provides a user interface for Android devices.
The Application Framework in Android enables developers to build applications by providing essential services and managing application components.
What are Android Architecture Components?
A set of libraries for building desktop applications.
A collection of web development tools.
A framework for developing iOS applications.
A set of libraries for building robust Android apps, including LiveData, ViewModel, Room, and Lifecycle.
What is the significance of Room in Android architecture?
Room is primarily used for UI design in Android applications.
Room simplifies database management in Android by providing an abstraction layer over SQLite, ensuring type safety and easier data access.
Room is a networking library for managing API calls in Android.
Room is a cloud-based database solution for Android.
Explain the concept of Lifecycle in Android components.
The lifecycle only applies to Activities, not Fragments.
Android components do not have a defined lifecycle.
Lifecycle states are irrelevant for resource management.
The lifecycle in Android components refers to the series of states that an Activity or Fragment goes through from creation to destruction, allowing developers to manage resources and UI effectively.
