Question

Accepted Answer

The interview questions cover a range of topics related to Android development, including Kotlin, Android 11 features, design patterns, and more.

Sealed classes are used for representing restricted class hierarchies, while enums are used for representing a fixed set of constants.
Activity Lifecycle and Fragment Lifecycle are important concepts in Android development for managing the state of activities and fragments.
Serialization in Java is the process of converting an object into a byte stream for storage or transmission.
Scope functions in Kotlin, such as let, run, apply, also, and with, provide concise ways to perform operations on objects.
Doze mode is a power-saving feature in Android that restricts app background activity to conserve battery life.
New features in Android 11 include improvements to privacy settings, chat bubbles, and enhanced 5G support.
Interprocess communication in Android can be achieved using AIDL (Android Interface Definition Language) for defining interfaces that other processes can use.
DI (Dependency Injection) design patterns help manage dependencies in an application by injecting them into classes rather than creating them within the class.
ViewModels in Android are used to store and manage UI-related data in a lifecycle-conscious way, and can be destroyed when no longer needed.
The Repository pattern is a design pattern that separates data access logic from business logic in an application.
Scoped Storage is a feature in Android that restricts access to a specific set of directories for apps to improve security and privacy.
Kotlin Flows are a type of asynchronous data stream in Kotlin that can emit multiple values over time.
Sticky Intents are broadcast Intents that stay active even after being broadcast, while Pending Intents are used for executing an action at a later time.
Player SDKs provide tools and libraries for developers to integrate audio and video playback functionality into their Android applications.
