Android Development Questions and Answers

What programming languages are used for Android development?

Android development primarily uses Kotlin and Java. Google officially recommends Kotlin as the preferred language since 2019. Kotlin is concise, null-safe, and interoperable with Java code. Java remains widely used in legacy Android codebases. Both languages use the Android SDK and run on the Android Runtime (ART) on Android devices.

What is the Android Activity lifecycle?

Android Activity lifecycle states include: onCreate() (initialization), onStart() (becoming visible), onResume() (interactive, foreground), onPause() (partially obscured), onStop() (no longer visible), onDestroy() (activity destroyed). Understanding this lifecycle is essential for managing resources correctly — saving data in onPause/onStop and releasing resources in onDestroy to prevent memory leaks.

What is Jetpack Compose and how does it differ from XML layouts?

Jetpack Compose is Android's modern declarative UI framework that replaces XML-based layout files. Instead of defining UI in XML and updating it imperatively, Compose lets you describe UI as Kotlin functions (Composables) that automatically recompose when state changes. Compose is more concise, easier to test, and better suited for complex dynamic UIs.

What is a RecyclerView in Android?

RecyclerView is Android's efficient list/grid display component that recycles (reuses) view holders as the user scrolls, dramatically improving performance over the older ListView. It requires: a LayoutManager (LinearLayoutManager, GridLayoutManager), an Adapter (connecting data to views), and ViewHolder objects. RecyclerView is the standard for displaying large or dynamic datasets in Android apps.

What is the difference between Service and IntentService in Android?

Service runs on the main thread and must manually manage threading. IntentService (deprecated in API 30) automatically ran on a worker thread and stopped itself when done. The modern replacement is WorkManager (for deferrable background work), Foreground Services (for user-aware long-running tasks like music playback), and Coroutines with lifecycle-aware components for async operations.

What are Android Intents and how are they used?

Intents are messaging objects used to request actions from other app components. Explicit Intents specify the target component (e.g., startActivity(Intent(this, TargetActivity::class.java))). Implicit Intents declare an action without specifying a component (e.g., viewing a URL opens a browser). Intents carry data as extras and can start activities, services, or broadcast events.
