01
How do you migrate from SharedPreferences to DataStore without losing user data?
Use SharedPreferencesMigration when creating the DataStore: preferencesDataStore(name = "settings", produceMigrations = { ctx -> listOf(SharedPreferencesMigration(ctx, "old_prefs")) }). On first access, DataStore copies the values and deletes the old file. Update all reads and writes to go through the new repository at once, because mixing both stores leads to inconsistent values. Test the migration with existing preference files.
02
What is the difference between a deep link and an Android App Link?
A deep link is any intent filter that opens your app for a URI; if several apps can handle it, the user sees a chooser. An App Link is an HTTPS deep link verified with android:autoVerify and a Digital Asset Links file at /.well-known/assetlinks.json on your domain, containing your app's signing certificate fingerprint. Verified links open your app directly. Remember to include the Play App Signing key fingerprint.
03
Write a manifest entry for a deep link that opens a product screen.
<activity
android:name=".MainActivity"
android:exported="true">
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="https"
android:host="shop.example.com"
android:pathPrefix="/product" />
</intent-filter>
</activity>
<!-- autoVerify plus assetlinks.json on the domain makes it an App Link -->
04
Write a Room entity and DAO for notes with a Flow query.
@Entity(tableName = "notes")
data class NoteEntity(
@PrimaryKey(autoGenerate = true) val id: Long = 0,
val title: String,
val body: String,
val updatedAt: Long
)
@Dao
interface NoteDao {
@Query("SELECT * FROM notes ORDER BY updatedAt DESC")
fun observeAll(): Flow<List<NoteEntity>>
@Upsert
suspend fun upsert(note: NoteEntity)
@Query("DELETE FROM notes WHERE id = :id")
suspend fun delete(id: Long)
}
05
You need to cache API responses so the home screen opens instantly. What approach do you take?
Store the response in Room, or a file for a single blob, and have the screen observe the cached data immediately while a refresh runs in the background, known as stale-while-revalidate. Store a timestamp to decide when cache is too old. HTTP caching with OkHttp Cache can also help for GET requests with proper cache headers. Show cached content first, then update smoothly when fresh data arrives.
06
How should a Fragment or Activity collect a Flow safely?
Use lifecycleScope.launch with repeatOnLifecycle(Lifecycle.State.STARTED) so collection starts when the UI is visible and stops in the background, avoiding wasted work and crashes from updating views that are not ready. In a Fragment, use viewLifecycleOwner.lifecycleScope because the fragment view can be destroyed while the fragment lives. In Compose, use collectAsStateWithLifecycle(), which does the same lifecycle-aware collection.
R8 shrinks code by removing unused classes and members, optimises bytecode by inlining and removing dead branches, obfuscates names to make reverse engineering harder and reduce size, and shrinks resources when enabled. It needs keep rules for code accessed by reflection, such as some serialization or SDK classes. Upload the mapping file to Play Console and Crashlytics so obfuscated stack traces can be decoded.
08
Write an OkHttp interceptor that adds a bearer token to every request.
You would use a client like Apollo Kotlin, which generates type-safe models from the schema and queries at build time, and supports normalised caching and coroutines. Benefits are fetching exactly the fields a screen needs and fewer round trips. Costs include learning the tooling, more complex caching and error handling since errors can come with partial data. I would pilot it on one feature before migrating everything.
10
Explain object, companion object and object expressions.
An object declaration creates a thread-safe singleton initialised lazily on first access. A companion object is an object tied to a class, used for factory methods and constants, similar to static members in Java; add @JvmStatic for Java callers. An object expression creates an anonymous object on the spot, often to implement an interface such as a callback. Avoid holding Context or Activity references in singletons to prevent memory leaks.
11
What are sequences in Kotlin and when are they better than collections?
Sequences evaluate lazily, element by element, while collection operations like map and filter create a new intermediate list at every step. For long chains on large data, or when you only need the first few results with take or first, asSequence() avoids extra allocations. For small lists, plain collections are often faster because sequences add per-element overhead. Measure before switching in performance-critical code.
12
After an app update, users report that the app crashes on launch. Logs show a Room migration error. What do you do?
Immediately halt the staged rollout in Play Console. Reproduce by installing the previous version, adding data, and upgrading. The schema version was probably increased without a matching migration, or a migration SQL does not match the new entity. Write the correct Migration, test it with MigrationTestHelper from every supported old version, and release a hotfix. Avoid destructive fallback because it deletes user data.
13
A crash report shows a NullPointerException in Kotlin code. How can that happen if Kotlin is null safe?
Common causes are the !! operator, platform types from Java code without nullability annotations, accessing a lateinit property before assignment, calling a function from a constructor before properties are initialised, and reflection-based libraries like Gson setting non-null fields to null. Fix it by removing !!, adding annotations or explicit nullable types at the Java boundary, and using a Kotlin-aware serializer such as kotlinx.serialization or Moshi with Kotlin codegen.
14
How do you find and fix memory leaks in an Android app?
Add LeakCanary to debug builds; it detects retained Activities, Fragments and ViewModels and shows the reference chain. Common leaks are static or singleton references to Context or Views, listeners not unregistered, inner classes holding Activity references, and Fragment view bindings not cleared in onDestroyView. Fix by using application context, lifecycle-aware components and weak references only where needed. Confirm with Memory Profiler heap dumps.
15
The backend team changed a field from a number to a string and the app crashed for all users. How do you prevent this?
Short term, make parsing lenient for that field, for example with a custom serializer, and handle parse failures without crashing. Long term, agree on API contracts with versioning, use contract tests or a shared OpenAPI schema checked in CI, add ignoreUnknownKeys and default values in kotlinx.serialization, and use remote config or a minimum supported app version mechanism. Monitor parse errors as non-fatal events.
16
The crash-free rate dropped after a release only on Android 15 devices. How do you respond?
Halt the staged rollout immediately. Filter Crashlytics or Play vitals by OS version to find the top crash, then check Android 15 behaviour changes such as edge-to-edge enforcement, foreground service rules or new restrictions affecting your target SDK. Reproduce on an Android 15 emulator, fix, add a test, and resume rollout with the hotfix. Afterward, add Android 15 devices to the regular test matrix.
17
How would you lead an architecture decision when senior developers disagree?
I would write a short decision document stating the problem, two or three options with trade-offs, and constraints such as team skill and timeline, then build a small spike of the top options on a real screen. We review with measurable criteria like test effort and build time, decide, and record it as an architecture decision record. Once decided, everyone commits, and we revisit only if new facts appear.
18
Write a Flow that combines user settings and product list into one UI state.
Interceptors observe or modify requests and responses in the OkHttp chain. Application interceptors run once per call and are used for adding auth headers, common query parameters or logging with HttpLoggingInterceptor. Network interceptors run for each network request including redirects and see the actual network bytes, useful for cache headers. Never log full bodies or tokens in release builds, because logs can leak sensitive data.
20
The APK size grew to 120 MB and installs from small towns are dropping. How do you reduce it?
Analyse the build with APK Analyzer. Publish as an App Bundle so users get only their density, language and ABI. Enable R8 and resource shrinking, convert images to WebP or vectors, remove unused libraries and duplicate dependencies, and move large optional features or assets to Play Feature Delivery or Play Asset Delivery. Avoid bundling all native libraries for every ABI. Track size in CI.
21
A text field loses its typed value after rotation. How do you fix it?
The value is probably held with remember, which is lost when the Activity is recreated. Either use rememberSaveable for local UI state, or keep the text in the ViewModel and pass it down with onValueChange. For data that must survive process death too, store it in SavedStateHandle in the ViewModel. Avoid storing text field state asynchronously, because delayed updates can cause cursor jumps.
22
The Play Store rejected your update for a policy violation about permissions. What do you do?
Read the rejection email and policy centre message carefully to see which permission or declaration failed, often SMS, call log, background location, all-files access or exact alarms. Remove the permission if a less sensitive alternative exists, such as the SMS Retriever API or photo picker. Otherwise update the permission declaration form with a clear use case and video. Check the merged manifest for permissions added by libraries.
23
How would you implement real-time order tracking updates in an app?
Options are polling, WebSockets, Server-Sent Events, or push notifications. For a live tracking screen, a WebSocket via OkHttp exposed as a callbackFlow works well, started when the screen is visible and closed when it leaves. Add reconnection with backoff, heartbeat pings, and fall back to polling on failure. When the app is in background, rely on FCM pushes for status changes instead of keeping the socket open.
24
Write a unit test for a ViewModel using a fake repository and runTest.
class ProductViewModelTest {
@get:Rule val mainRule = MainDispatcherRule()
@Test
fun loadsProductsIntoState() = runTest {
val fake = FakeProductRepository(listOf(Product("1", "Pen", 10.0)))
val vm = ProductViewModel(fake)
advanceUntilIdle()
val state = vm.state.value
assertFalse(state.loading)
assertEquals(1, state.items.size)
assertNull(state.error)
}
}
25
Tell me about a time you handled a production crash under pressure.
Situation: after a release, crash-free users dropped from 99.6 to 97 percent. Task: stop the impact fast. Action: I checked Crashlytics, found a crash on Android 14 caused by a missing foreground service type, paused the staged rollout in Play Console, shipped a hotfix with a test on an emulator for that API level, and wrote a short postmortem. Result: crash rate recovered within a day and we added API-level checks to our release checklist.
26
Explain LaunchedEffect, DisposableEffect and SideEffect.
LaunchedEffect(key) launches a coroutine when it enters composition and restarts when the key changes, used for one-time loads or showing a snackbar. DisposableEffect(key) runs setup and requires an onDispose block for cleanup, used for registering listeners or lifecycle observers. SideEffect runs after every successful recomposition to publish Compose state to non-Compose code, such as analytics. Choose keys carefully so effects do not restart unexpectedly.
27
A new developer asks why we need interfaces for every repository. How do you answer?
Interfaces let us swap implementations, mainly fakes in tests and alternate data sources, and they define clear contracts between modules so feature modules depend on abstractions instead of concrete network code. But the rule is not absolute: if a class has one implementation and is easy to test directly, an interface adds noise. I would explain the reason with an example test and our team convention.
28
The app's cold start takes 4 seconds. How do you improve it?
Measure first with Macrobenchmark StartupTimingMetric on a release build. Then reduce work in Application.onCreate by deferring SDK initialisation, using App Startup or lazy injection, and moving disk I/O off the main thread. Simplify the first screen, avoid blocking on network before showing UI, use the SplashScreen API properly, and add a Baseline Profile, which often improves startup by about 20 to 30 percent.
29
The app shows an ANR when the user taps Save. The save function is suspend. What could be wrong?
A suspend function does not automatically run off the main thread. If it calls blocking code, like a synchronous file write, a SharedPreferences commit, a blocking SDK or heavy JSON parsing, it still blocks the main thread. Check with a profiler or StrictMode. Fix by wrapping the blocking part in withContext(Dispatchers.IO) or Default, or by using main-safe APIs such as Room suspend DAOs or DataStore.
30
What file storage options does Android provide and how does scoped storage affect them?
App-specific storage (filesDir, cacheDir, getExternalFilesDir) needs no permission and is deleted on uninstall. Shared media is accessed through MediaStore, and other documents through the Storage Access Framework. Since Android 10, scoped storage blocks broad file system access, and since Android 13 media permissions are split into images, video and audio. The photo picker lets users choose media without any permission, which is preferred.
