Years of Android in production mean we've already hit the walls most teams discover at scale — ANR crashes nobody can reproduce, RecyclerView jank on budget hardware, Play Store rejections from a policy the app never considered. This page is about what's inside a modern Android app, and how a Java XML codebase moves to Kotlin Compose without stopping releases.
Why Entalogics for Android
Android is harder than iOS for one reason: fragmentation. The same app has to work on a mid-range Samsung, a Pixel tablet, and a two-year-old Xiaomi with half the RAM. Plenty of teams test on three devices and call it done. We test on the devices your users carry.
We profile with Android Studio's CPU Profiler and Perfetto from the start, rather than after the Play Console starts reporting ANRs. Lists use DiffUtil and the ViewHolder pattern. Background work goes through WorkManager. A dropped frame on a mid-range phone reads as a one-star review.
Each feature in an Android development project lives in its own Gradle module with explicit dependencies. The app module wires them together — it doesn't own business logic. ViewModels survive configuration changes. Repositories own data, not Fragments. Two engineers work on two features without a merge conflict every afternoon.
LiveData lives where it belongs — UI observation. Flow handles everything else: API calls, database streams, background work coordination. StateFlow for UI state that survives recomposition. SharedFlow for one-shot events. Each one chosen for the job rather than carried over from a tutorial.
Data classes for every API response, sealed interfaces for domain state, Result types for expected failures. Kotlin Coroutines handle concurrency without the callback hell that made Java Android development infamous. When a backend field changes, the Kotlin compiler finds every broken callsite before QA runs.
When Android native, when not
Native Kotlin gives you the deepest access to the Android platform. It also costs more: two codebases, two sets of engineers, two store submission processes. On the first call we'll tell you whether native is justified or whether cross-platform gets you the same result faster.

What we build for Android
The kinds of Android work we do most often, each built to pass Play Store review on the first submission and hold up on the phones your users carry.
Full consumer Android app development stack: onboarding that converts, Google Play Billing for subscriptions with server-side validation, Firebase Cloud Messaging for push, App Widgets for the home screen, and Play Store listing assets that pass the policy review.
Android Enterprise provisioning, MDM compatibility, certificate pinning, biometric authentication through BiometricPrompt, offline-first sync for teams working without reliable connectivity. Built for regulated environments where security is a requirement rather than a feature.
XML View-based apps migrated to Jetpack Compose — screen by screen, never a flag-day. The app stays on Google Play throughout. Each migration step behind a feature flag with its own rollback path.
Wear OS apps that share a Kotlin codebase with the phone app through shared modules. Health Sensors API, background health tracking, tile and complication providers — Android development that reaches the wrist.
Replace the spreadsheet your Android field team photographs and emails every afternoon — barcode scanning with ML Kit, offline form submissions synced when connectivity returns, GPS tracking with FusedLocationProvider. Tested on the same budget phones your warehouse team uses.
Java Android apps still running Android Support Library get migrated to Kotlin and Jetpack — one module at a time, interoperability maintained throughout. The technical debt that slows every new feature gets resolved without stopping product delivery.
The playbook
The patterns we use on production Android apps, tested on real devices rather than only Pixel emulators.
PP01
New screens go in Jetpack Compose with Material 3. XML Views stay for components Compose doesn't handle as cleanly yet — custom SurfaceView rendering, specific RecyclerView animations. We don't mix the two without a reason.
PP02
Kotlin Coroutines replace every AsyncTask, Handler, and thread pool that made Java Android development hard to read. ViewModelScope for UI work, IO Dispatcher for network and database, structured concurrency for parallel work that cancels cleanly when the ViewModel clears.
PP03
Constructor injection for every ViewModel, Repository, and UseCase. No Singleton objects that make tests impossible. No manual dependency graphs that break when a class gets a new constructor parameter. Hilt catches misconfiguration at compile time.
PP04
Colour, typography, and spacing defined once in a MaterialTheme, not hardcoded across two hundred composables. Dynamic Colour for Android 12+ where the system palette applies automatically. Dark mode, large text, and high contrast fall out of one token definition.
PP05
Espresso covers the flows where a regression costs money — login, purchase, deep link. Paparazzi captures composable screenshots for visual regression. Both run in CI on every PR without a physical device being plugged in.
PP06
ComposeView embeds Compose screens inside Fragment-based navigation. AndroidView embeds legacy XML where Compose hasn't caught up yet. The migration is gradual, the app ships continuously, and no quarter gets frozen to pay for a rewrite.
Engagement shape
A typical Android engagement, end to end. Screen by screen, with the current app on Google Play the whole time.
Two senior Android developers go through the codebase — CPU profiling to find the real ANR candidates, a Fragment complexity inventory, a WorkManager audit for silent background failures, and a Play Store policy check. The output is a ranked RFC with effort estimates.
Kotlin and Compose baseline, Hilt wiring, ViewModel boundaries established, one production screen built end-to-end and pushed to the internal testing track. Performance numbers come from a physical mid-range Android phone, not a Pixel emulator.
Feature by feature under feature flags, Java XML and Kotlin Compose coexisting. Each cutover has a rollback path. Your product team keeps shipping new features in parallel — the Android development migration never becomes a reason to freeze the roadmap.
Store listing assets, content rating questionnaire, data safety form, policy compliance check, first submission to production track. Google Play review typically runs 1–3 business days. Runbook handed to your team — or we stay on retainer.
Stack

Verified feedback from Upwork, Clutch, and reference calls we're happy to set up before you sign anything.
CEO, Modestly
Entalogics has successfully delivered extension prototypes on time, and we are impressed with their project management and the finished product. The client communicates with Entalogics via virtual meetings, email, and messaging apps.
Founder, Flourish Schools
Collaborating with Entalogics was a great experience. Communication was clear, we aligned quickly, and their team delivered high-quality code on time with thoughtful technical decisions.
CTO, SentryBay
Their Chromium expertise helped us ship a hardened browser with live threat controls and enterprise rollout support. Security operations became significantly faster.
Founder, G3 Ventures LLC
Entalogics delivered our custom Electron browser in six months with isolated profile workflows and stable policy sync. Agent onboarding improved by 55% after rollout.
Project Manager, Sociall
Entalogics built our iOS Chromium-based mobile app with a smooth native feel, stable media rendering, and reliable sync. We shipped faster and improved engagement after launch.
RozmeriGPT
The web dashboard and Chrome extension now share prompts, billing, and analytics in one platform. Our content turnaround improved 4x after launch.
Project Manager, Omni Browser
Entalogics built our Omni Browser on top of Chromium with deep product-level execution. They implemented an integrated VPN and Omni Crypto Wallet directly in the browser, made strong architectural decisions, and delivered quality code on schedule with clear communication.
Project Manager, Digital Office: Aura
Entalogics built Digital Office: Aura as a custom Chromium-based authentication platform. Their team modified Chromium internals and integrated our manual custom authentication flow with reliable implementation, fast delivery, and consistent communication.
Engagement
