Q2. What is the difference between Stateful and Stateless widgets in Flutter?
Stateful widgets maintain state that might change during the lifetime of the widget, while stateless widgets are immutable and do not change.
Stateful widgets have a State object that can hold dynamic information and can be updated over time.
Stateless widgets are immutable and their properties cannot change once they are initialized.
Stateful widgets are used when the UI can change dynamically based on user interactions or other factors.
Stateless widgets are used for static con...read more
Q3. What are the life cycles of Activity and Fragment in Android development?
Activity and Fragment have different life cycles in Android development.
Activity life cycle includes onCreate, onStart, onResume, onPause, onStop, onDestroy
Fragment life cycle includes onAttach, onCreate, onCreateView, onActivityCreated, onStart, onResume, onPause, onStop, onDestroyView, onDestroy, onDetach
Activity can contain multiple fragments with their own life cycles
Q4. What is co routines in Kotlin, and how does it differ from AsyncTask and WorkManager?
Coroutines in Kotlin are lightweight threads that help manage asynchronous tasks efficiently.
Coroutines are more efficient than AsyncTask as they can handle multiple tasks concurrently without creating new threads.
Coroutines are more flexible and easier to use compared to AsyncTask.
Coroutines can be easily cancelled, unlike AsyncTask which can lead to memory leaks if not handled properly.
WorkManager is recommended for background tasks that need to be guaranteed to run, while ...read more
Q5. What are the differences between Native, Hybrid, and Cross Platform development?
Native, Hybrid, and Cross Platform development differ in their approach to building mobile applications.
Native development involves building apps specifically for a single platform using the platform's native programming languages and tools (e.g. Java/Kotlin for Android, Swift/Objective-C for iOS).
Hybrid development uses web technologies like HTML, CSS, and JavaScript to build apps that can run on multiple platforms with the help of frameworks like React Native or Ionic.
Cross...read more
Q6. What tools or techniques do you use for managing state in Flutter and native Android development?
In Flutter, I use Provider package for state management. In native Android development, I use LiveData and ViewModel.
In Flutter, use Provider package for managing state efficiently
In native Android development, use LiveData and ViewModel to handle state changes
Consider using Redux or MobX for more complex state management in Flutter
Q7. Does Kotlin support native development for Android?
Yes, Kotlin supports native development for Android through the use of Kotlin/Native.
Kotlin/Native allows developers to compile Kotlin code directly to native binaries, which can be used for Android development.
It enables developers to write platform-specific code in Kotlin for Android apps.
Kotlin/Native also supports interoperability with existing native code written in C or C++.
Q8. What are the SOLID principles of software development?
SOLID principles are a set of five design principles that help make software more maintainable, flexible, and scalable.
S - Single Responsibility Principle: A class should have only one reason to change.
O - Open/Closed Principle: Software entities should be open for extension but closed for modification.
L - Liskov Substitution Principle: Objects of a superclass should be replaceable with objects of its subclasses without affecting the program's correctness.
I - Interface Segreg...read more
Q9. What are the Grey and Red Errors in Flutter?
Grey errors in Flutter are compile-time errors, while red errors are runtime errors.
Grey errors are compile-time errors that prevent the code from being compiled and run, such as syntax errors or type mismatches.
Red errors are runtime errors that occur while the code is running, such as null pointer exceptions or out-of-bounds errors.
Q10. What is Reactive Programming?
Reactive Programming is a programming paradigm that focuses on asynchronous data streams and the propagation of changes.
Uses observables to handle data streams and propagate changes
Emphasizes declarative programming and event-driven architecture
Commonly used in frameworks like RxJava, RxJS, and Reactor
Q11. What are the applications of the Java programming language, and can you explain the Object-Oriented Programming (OOP) concepts?
Java is used in a wide range of applications such as web development, mobile apps, enterprise software, and more. OOP concepts include classes, objects, inheritance, polymorphism, and encapsulation.
Java is commonly used in web development to create dynamic websites and web applications.
Mobile app development for Android platform heavily relies on Java programming language.
Enterprise software development often utilizes Java for its scalability and reliability.
OOP concepts in J...read more
Q12. What are callback functions and reference functions?
Callback functions are functions passed as arguments to other functions to be executed later. Reference functions are functions that are referenced by a variable.
Callback functions are commonly used in event handling, asynchronous operations, and array methods like map, filter, and reduce.
Reference functions are functions that are assigned to a variable and can be called using that variable.
Example of callback function: setTimeout(function(){ console.log('Hello') }, 1000);
Exa...read more

Q14. Explain the paid ads strategy
Paid ads strategy involves targeting the right audience, selecting the right platform, and optimizing ad content to achieve desired results.
Identify target audience based on demographics, interests, and behavior
Select appropriate platform(s) such as Google Ads, Facebook Ads, or LinkedIn Ads
Create compelling ad content with clear call-to-action
Set budget and bid strategy to maximize ROI
Monitor and optimize ad performance regularly
Q15. What is DHCP server
DHCP server assigns IP addresses to devices on a network automatically.
Automatically assigns IP addresses to devices on a network
Helps in reducing manual configuration efforts
Manages IP address allocation efficiently
Prevents IP address conflicts
Example: When a new device connects to a network, DHCP server assigns it an IP address
Q16. How lan lan works
LAN stands for Local Area Network, which is a network of interconnected devices within a limited area such as a home, office, or building.
LAN connects devices within a limited area using Ethernet cables or wireless technology.
LAN allows devices to share resources such as files, printers, and internet access.
LAN is typically used in homes, offices, schools, and small businesses.
LAN can be set up using a router or switch to connect devices.
LAN can be wired or wireless, with wir...read more
