Top 5 Technical Interview Questions Asked for Android Developer
- Why it’s asked: This question tests your understanding of how Android manages application states and how you handle different lifecycle events to maintain app performance and user experience.
- Sample Answer: The Android Activity Lifecycle consists of several states:
onCreate(),onStart(),onResume(),onPause(),onStop(),onRestart(), andonDestroy(). Each method is called in a specific order as the activity transitions from one state to another. Understanding these states allows developers to manage resources, save data, and ensure the app behaves correctly as the user interacts with it or as the system changes its state.
- Why it’s asked: Managing background tasks efficiently is crucial for building responsive and battery-efficient apps. This question checks your knowledge of Android’s background processing capabilities.
- Sample Answer: Background tasks in Android can be handled using several APIs depending on the nature of the task. For short-lived tasks,
AsyncTaskwas traditionally used, but it is now deprecated in favor ofExecutorServiceandHandlerThread. For longer tasks,WorkManageris the recommended solution as it provides a consistent API for managing deferrable, guaranteed background work. For immediate tasks that need to be done in the background,IntentServiceorJobIntentServicecan be used.
- Why it’s asked: Understanding the role of
FragmentsandActivitiesin Android helps in designing modular, maintainable apps. - Sample Answer:
Activityis the entry point for interacting with the user. It usually hosts the app’s UI and manages its lifecycle.Fragmentsare reusable components that can be embedded withinActivitiesor otherFragments, allowing for more modular and flexible UI designs. Fragments are particularly useful for creating dynamic UIs that can adjust to different screen sizes, such as in tablets versus smartphones.
- Why it’s asked: Custom views are often required for creating unique UI components. This question assesses your ability to extend Android’s standard views to meet specific design requirements.
- Sample Answer: To implement a custom
View, you need to extend theViewclass (or any of its subclasses) and override itsonDraw()method to define how it should be rendered on the screen. You may also need to overrideonMeasure()to specify how the view should measure itself and its children. Custom attributes can be defined in XML to allow for more flexible use of the custom view in different layouts.
- Why it’s asked: Memory leaks can lead to performance issues and crashes. This question tests your knowledge of best practices for managing memory in Android.
- Sample Answer: Memory leaks in Android can often occur due to improper handling of
Contextobjects or static references. To avoid memory leaks, you should be careful with long-lived objects holding references toActivityorContext. Using weak references, clearing references inonDestroy(), and using tools like Android Profiler and LeakCanary for monitoring memory usage can help identify and prevent leaks. Avoid anonymous inner classes or non-static inner classes that hold implicit references to outer classes, as they can unintentionally prevent the garbage collector from freeing up memory.
