Interview Questions to Ask Before You Hire Android Developers
Identify the right fit faster with these targeted technical and behavioral questions.
Kotlin & Java Fundamentals
What’s the difference between 'var' and 'val' in Kotlin?
var declares a mutable variable; val is read-only after initialization, enforcing immutability.
How do you handle null safety in Kotlin?
Use nullable types String?, the safe-call operator ?., Elvis ?:, and non-null assertions !! to avoid NPEs at compile time.
Explain extension functions and give an example use case.
They let you “add” methods to existing classes, e.g., fun String.snakeToCamel(): String for name conversions.
When would you choose Java over Kotlin on Android?
Legacy codebases or libraries without Kotlin support; otherwise, Kotlin’s conciseness and safety make it the default choice.
UI & Jetpack Compose
What benefits does Compose offer over XML layouts?
Declarative UI, less boilerplate, real-time previews, easier state management, and full Kotlin integration.
How do you manage theming (light/dark) in Compose?
Wrap setContent in a theme composable using MaterialTheme colors/typography and switch based on system UI mode.
Explain how you’d build a RecyclerView-style list in Compose.
Use LazyColumn with items(list) { item -> Row(item) } for efficient scrolling.
What is Modifier in Compose?
A fluent API to define layout/drawing/input, e.g., Modifier.padding(16.dp).fillMaxWidth().
Architecture & Design Patterns
What is MVVM and how does it improve Android code?
It separates UI (View) from state/logic (ViewModel) and data (Model), exposing observable state via LiveData/Flow for testability and maintainability.
How does MVI differ from MVVM?
MVI enforces a single immutable state and unidirectional flow—user Intents in, new State out, making transitions explicit.
Describe the Clean Architecture layers in an Android app.
• Presentation: UI + ViewModels
• Domain: Business use-cases (pure Kotlin)
• Data: Repository implementations, network/DB
How would you migrate a legacy Activity/UI to use ViewModel?
Move logic into a ViewModel, expose state via LiveData/StateFlow, observe it from the Activity/Fragment.
Performance & Memory
What causes ANRs and how do you prevent them?
Blocking the main thread > ~5s. Offload work via coroutines/Rx/background threads; keep UI thread free.
How do you detect and fix memory leaks?
Use LeakCanary/Memory Profiler; avoid static Context refs, unregister listeners in onDestroy.
What is view binding vs. findViewById?
View Binding generates type-safe bindings at compile time, removing manual findViewById and NPE risk.
How do you optimize image loading?
Use Glide/Coil with placeholders, caching, resizing, and proper formats before display.
Dependency Injection
What is Hilt and how does it simplify Dagger?
Hilt layers on Dagger with Android-ready components and annotations like @HiltAndroidApp, @AndroidEntryPoint to cut boilerplate.
How do you scope dependencies in Hilt?
Use @Singleton, @ActivityScoped, @ViewModelScoped on @Provides/@Inject constructors.
When use constructor vs. field injection?
Constructor for mandatory deps (immutable/testable); field injection for Android framework classes.
How can you replace a Hilt module for testing?
Provide a test module annotated @TestInstallIn targeting the same component.
Red Flags to Watch For
⭕ Can’t explain Kotlin’s null-safety clearly
⭕ Only knows XML UI, no Compose exposure
⭕ Weak or nonexistent test suites (unit & UI tests)
⭕ No CI/CD pipeline familiarity
Additional Interview Questions
Testing (Unit & UI)
Unit vs. Instrumentation tests, when to use each?
Unit (JUnit/Mockito): fast JVM logic tests. Instrumentation (Espresso): device/emulator UI & integration flows.
How do you mock Android SDK classes in unit tests?
Use interfaces/wrappers or Robolectric for a JVM Android environment.
Give an example of an Espresso UI test.
onView(withId(R.id.loginButton)).perform(click()); onView(withId(R.id.welcomeText)).check(matches(isDisplayed()))
What is MockK and why choose it over Mockito?
Kotlin-first mocking; supports final classes and coroutines with a concise DSL, less ceremony than Mockito in Kotlin.
Asynchronous Programming
What is structured concurrency in Kotlin coroutines?
Work is tied to a CoroutineScope; child coroutines cancel when the scope (e.g., viewModelScope) is cleared.
How do you handle errors in coroutines?
try/catch inside launch/async and a CoroutineExceptionHandler at scope level.
When would you use Flow over LiveData?
Flow is Kotlin-native, has operators (map/filter/zip), supports backpressure, and integrates with coroutines.
Why might you choose RxJava over coroutines?
For complex multi-stream compositions using rich operators, classic reactive pipelines.
CI/CD & Firebase Deployment
Describe a basic CI pipeline for Android.
Checkout → ./gradlew build → ./gradlew test → assemble release .aab.
How do you secure your keystore in CI?
Store keystore and passwords as CI secrets, decrypt at runtime, sign with Gradle tasks.
What is Firebase App Distribution?
A service to distribute test builds to QA/users and collect feedback/crash data before Play release.
How do you automate Play Store uploads?
Use the Play Developer API via Gradle play-publisher or a GitHub Actions step to push the .aab to an internal track.
App Security Best Practices
Why follow least-privilege for permissions?
It minimizes attack surface and increases user trust, request only what the app truly needs.
How do you store API keys securely?
Keep secrets off the APK; use a backend or Android Keystore plus EncryptedSharedPreferences/EncryptedFile.
How do you prevent SQL injection in Room/SQLite?
Always use parameterized queries, e.g., @Query("SELECT * FROM users WHERE id = :userId").
What’s WebView hardening best practice?
Disable file access, restrict JS interfaces, enforce HTTPS, and validate URLs before loading; avoid exporting components with android:exported="false" unless required; declare sensitive permissions like POST_NOTIFICATIONS explicitly.
