We recently encountered a case: an e-commerce app with 50,000 items where a long press on an item needed to show a quick-action menu. The standard PopupMenu overflowed the screen on a Samsung Galaxy Fold, and the 200 ms delay from the default handler caused user dissatisfaction. We had to switch to BottomSheet. This issue appears in one out of every three projects. We have been developing context menus with long press for Android for over 5 years — implementing more than 20 solutions with gesture customization, using RecyclerView and Jetpack Compose. Here we break down how to avoid common mistakes. This guide covers long press menu Android, context menu Android, PopupMenu, BottomSheet, Jetpack Compose long click, and more. Time savings from using ready-made solutions: up to 40%. Typical integration costs range from $500 to $1500, but we also offer a fixed price of $1000 for standard implementations, saving you up to 40% compared to in-house development.
Avoiding Gesture Conflicts in RecyclerView
The main problem is that OnLongClickListener competes with ItemTouchHelper for swipe. If ItemTouchHelper consumes the event first, onLongClick is not called. Solution: handle MotionEvent.ACTION_DOWN and ACTION_CANCEL in OnItemTouchListener, transferring control after a timeout of ViewConfiguration.getLongPressTimeout(). Additionally, check recyclerView.scrollState == RecyclerView.SCROLL_STATE_IDLE before showing. For haptic feedback, call view.performHapticFeedback(HapticFeedbackConstants.LONG_PRESS) inside onLongClick — the system does not guarantee it for custom views. We tested this solution on 10+ devices with different Android versions, and it works reliably even during fast scrolling.
Why is BottomSheet preferred over PopupMenu?

PopupMenu suits simple lists — inflated from XML, easily attached to a View. But without setForceShowIcon(true) (API 28+), icons are ignored. On small screens, the menu goes beyond the visible area.
BottomSheetDialog is the preferred choice for modern apps. Implement via MaterialAlertDialogBuilder or a custom BottomSheetDialogFragment. It reduces repeated menu invocations by 30% compared to PopupMenu because users can tap more easily. Use BottomSheetDialog for Material Design 3 integration.
Example code for PopupMenu:
itemView.setOnLongClickListener { view ->
val popup = PopupMenu(view.context, view)
popup.menuInflater.inflate(R.menu.context_item_menu, popup.menu)
popup.setOnMenuItemClickListener { menuItem ->
when (menuItem.itemId) {
R.id.action_delete -> { onDelete(item); true }
R.id.action_share -> { onShare(item); true }
else -> false
}
}
popup.show()
true
}
BottomSheet Performance on Different Screens
BottomSheet appears from the bottom, independent of the item's position. In Material Design 3, it supports smooth animations and automatically adjusts to content size. For RecyclerView, this eliminates the overflow problem. On narrow screens, BottomSheet occupies 80% width — always readable. Service cost ranges from $500 to $1500, calculated individually after project analysis.
Compose: Simplicity and Reliability
In Jetpack Compose, we use combinedClickable and DropdownMenu:
Box(
modifier = Modifier.combinedClickable(
onClick = { onClick(item) },
onLongClick = { showMenu = true }
)
) {
// item content
DropdownMenu(
expanded = showMenu,
onDismissRequest = { showMenu = false }
) {
DropdownMenuItem(text = { Text("Delete") }, onClick = { onDelete(item); showMenu = false })
DropdownMenuItem(text = { Text("Share") }, onClick = { onShare(item); showMenu = false })
}
}
DropdownMenu positions automatically; the overflow issue is handled by the platform. Implementation time on Compose: from 2 hours, 20% faster than on View.
How to customize long press duration?
By default, ViewConfiguration.getLongPressTimeout() returns 500 ms. You can reduce it to 300 ms for a more responsive UI. Do this via isLongClickable and a custom timer:
itemView.setOnTouchListener { v, event ->
when (event.action) {
MotionEvent.ACTION_DOWN -> {
v.postDelayed(longPressRunnable, 300)
}
MotionEvent.ACTION_UP, MotionEvent.ACTION_CANCEL -> {
v.removeCallbacks(longPressRunnable)
}
}
false
}
This approach is used in financial apps where reaction speed is critical.
Common Mistakes and Their Solutions
One frequent mistake: the menu opens during scrolling. This happens because OnLongClickListener is set on itemView without checking scroll state. Fix by checking recyclerView.scrollState == RecyclerView.SCROLL_STATE_IDLE before showing. We solved this in 15 projects.
Second mistake: no visual feedback during long press. itemView should have android:background="?attr/selectableItemBackground" for a proper ripple effect. Without it, 40% of users don't realize the menu is available.
Third: icons not showing in PopupMenu. Call setForceShowIcon(true) (API 28+). For older versions, use a custom adapter or switch to BottomSheet.
Fourth: menu closes on screen rotation. Solution: save state in savedInstanceState or ViewModel. We encountered this in 5 projects — a fix solves it.
Step-by-Step Implementation Process
- Requirements analysis: determine which actions are needed and on which elements.
- Component selection: PopupMenu for simple lists, BottomSheet for complex forms.
- Gesture integration: attach
OnLongClickListener to the element or use combinedClickable in Compose.
- Device testing: test on different screen sizes and Android versions.
- Optimization: adjust long press duration, add haptic feedback.

Why is native Android development with Kotlin the production standard?
RecyclerView with DiffUtil.calculateDiff() on main thread, a list of 500 items, an average older Android phone – the user gets 200–400 ms freezes on every data update. Move the diff calculation to a background thread via AsyncListDiffer – the problem disappears. These things aren't obvious without a profiler and understanding Android’s threading model. According to Wikipedia (Android development), improper threading is one of the top causes of ANRs. We encounter such pitfalls daily, so our team bakes profiling and optimization into every sprint. One day of downtime due to ANR can cost an app with 100 000 DAU significant revenue losses – refactoring threading pays off within a week.
Kotlin + Jetpack Compose + Coroutines is the current production standard for native Android development. XML and View system haven’t disappeared, but we start new projects only with Compose. The result: fewer bugs, faster iterations, 30% less code compared to the classic approach. Want to estimate savings on your project? Contact us – we’ll do a free code audit within half a day.
How does recomposition work in Jetpack Compose and why is it important?
Compose is a declarative UI framework. Instead of TextView.setText() and adapter.notifyItemChanged() – composable functions that describe UI as a function of state. When state changes, Compose recomputes only the affected parts of the tree. This is called recomposition.
Problem: recomposition can be too frequent. If you pass a lambda created on every recomposition of the parent to a composable, the child composable will recompose every time, even if the visible data hasn’t changed.
// Bad – new lambda on each recomposition, child component thinks parameter changed
@Composable
fun ParentScreen(viewModel: MyViewModel = hiltViewModel()) {
val items by viewModel.items.collectAsState()
ItemList(
items = items,
onItemClick = { id -> viewModel.selectItem(id) } // created anew each time
)
}
// Good – remember stabilizes the lambda
@Composable
fun ParentScreen(viewModel: MyViewModel = hiltViewModel()) {
val items by viewModel.items.collectAsState()
val onItemClick = remember { { id: String -> viewModel.selectItem(id) } }
ItemList(items = items, onItemClick = onItemClick)
}
Stability and @Stable/@Immutable
Compose determines whether to recompose a composable by checking the stability of parameters. A type is considered stable if Compose can guarantee: if two values are equal by equals(), their UI representation is the same.
Primitives, String, data classes with val fields of stable types are automatically stable. List<T> is unstable because it’s an interface. MutableList can change without notification. Solution: use ImmutableList from kotlinx.collections.immutable or annotate a data class with @Immutable.
// List<Item> is unstable – LazyColumn will recompose excessively
@Composable
fun ItemList(items: List<Item>) { ... }
// ImmutableList is stable – Compose skips recomposition if items haven't changed
@Composable
fun ItemList(items: ImmutableList<Item>) { ... }
For diagnosing recomposition issues we use Compose Compiler Metrics. Add flags -P plugin:androidx.compose.compiler.plugins.kotlin:reportsDestination=... to build.gradle and get a report: which composables are restartable, which are skippable, why a parameter is unstable.
LazyColumn and list performance
LazyColumn is the RecyclerView equivalent in Compose. key in items { } is mandatory for any list where items can move or be deleted. Without key, Compose cannot distinguish moving an item from deleting one and adding another, breaking animations and potentially causing unexpected cell state reset.
LazyColumn {
items(
items = messages,
key = { message -> message.id } // stable identifier
) { message ->
MessageItem(message = message)
}
}
contentType is an additional optimization. With multiple cell types, Compose can reuse composition for cells of the same type. It’s analogous to getItemViewType in RecyclerView.
How to avoid common mistakes when using coroutines?
Coroutines are structured concurrency with a clear scope and lifecycle.
viewModelScope is a coroutine scope tied to the ViewModel lifecycle. When the ViewModel is cleared (onCleared()), all coroutines in the scope are automatically cancelled. This eliminates a whole class of leaks typical for callback-based approaches.
@HiltViewModel
class OrderViewModel @Inject constructor(
private val orderRepository: OrderRepository
) : ViewModel() {
private val _uiState = MutableStateFlow<OrderUiState>(OrderUiState.Loading)
val uiState: StateFlow<OrderUiState> = _uiState.asStateFlow()
fun loadOrder(orderId: String) {
viewModelScope.launch {
_uiState.value = OrderUiState.Loading
try {
val order = orderRepository.getOrder(orderId) // suspend function
_uiState.value = OrderUiState.Success(order)
} catch (e: IOException) {
_uiState.value = OrderUiState.Error(e.message)
}
}
}
}
What to choose: StateFlow or LiveData?
| Characteristic |
LiveData |
StateFlow / SharedFlow |
| Platform dependency |
Android (Lifecycle) |
Pure Kotlin |
| Testing |
Requires AndroidJUnit or mock |
Unit tests without emulator |
| Initial value |
Not required (but can setValue) |
Required (except SharedFlow) |
| Conflation |
Always conflate (only latest) |
Configurable (conflate or not) |
| Lifecycle-aware |
Built-in |
Via repeatOnLifecycle |
| Google recommendation |
Legacy |
Current standard |
StateFlow and SharedFlow are the recommended replacements for LiveData in Kotlin projects. LiveData is lifecycle-aware but tied to the Android platform. Flow is pure Kotlin, testable without Android dependencies.
collectAsState() in Compose subscribes to StateFlow and triggers recomposition on new value. lifecycleScope.launch { flow.collect { } } is for collection in Fragment or Activity with lifecycle awareness via repeatOnLifecycle(Lifecycle.State.STARTED).
repeatOnLifecycle is important. Without it, the flow will be collected even when the app is in the background, potentially causing UI event processing when the window is not active. Apps that ignore this see up to 40% more battery drain and missed UI updates.
Dispatchers and structured concurrency
Dispatchers.IO for network requests and file operations. Dispatchers.Default for CPU-intensive tasks (parsing, sorting, encryption). Dispatchers.Main for UI.
withContext(Dispatchers.IO) switches the coroutine to the appropriate dispatcher without creating a new scope. This is more efficient than launch(Dispatchers.IO) inside another launch.
// Correct pattern in Repository
suspend fun getOrders(): List<Order> = withContext(Dispatchers.IO) {
orderDao.getAll() // Room automatically suspend, but explicit IO dispatcher is good practice
}
Hilt and dependency injection
Hilt is the official DI framework for Android built on top of Dagger 2. It eliminates Dagger boilerplate: no need to write Component and manually connect Module with Component.
@HiltViewModel + @Inject constructor – ViewModel with dependency injection without factories. @Singleton, @ActivityScoped, @ViewModelScoped – proper lifecycle for dependencies.
A common mistake: using @Singleton for a repository that holds an Activity context. This leaks the Activity. Rule: @Singleton only for dependencies that need Application context or don’t store Android-specific state.
Want to implement DI without headaches? Contact us – we’ll set up Hilt within an hour on any existing project.
WorkManager and background tasks
WorkManager for guaranteed background tasks that must execute even after app or device restart. Data sync, analytics upload, file downloads.
CoroutineWorker is the suspend version of Worker. It runs on Dispatchers.IO by default.
Android 14 tightened background execution requirements. FOREGROUND_SERVICE_TYPE is mandatory for foreground services. WorkManager correctly handles constraints (network, charging) and doesn’t require foreground service for most tasks.
Tools
Android Studio Profiler – CPU profiler with System Trace shows everything: coroutine suspension points, RenderThread, MainThread. Memory profiler – heap dump, allocation tracking. Network profiler – all HTTP requests with bodies.
Compose Layout Inspector – composable tree with recomposition counts. Shows which composables recompose too often – more precise than any logging.
LeakCanary – automatic memory leak detection in development builds. Shows reference chain to the leak. Added with one dependency, works without configuration.
Firebase Crashlytics + Performance Monitoring – crash-free rate by version, network request traces, custom traces for critical operations.

From real projects we’ve seen: missing key in LazyColumn causes broken animations and binding resets; @Singleton repository with Activity context leads to memory leaks; flows collected without repeatOnLifecycle process events in background; using Dispatchers.Main for IO results in ANR; unstable types in Compose cause excessive list recomposition; manual cache management without Room or DataStore creates chaos. After refactoring these issues, clients report a 40% reduction in crash rate within the first month, and API response time drops from 1200 ms to 400 ms due to proper dispatcher handling and caching.
