Android Apps Built to Perform Across Every Device

We build native Android apps in Kotlin with comprehensive device testing and Material Design 3 — so your app works well everywhere, not just the flagship your developer uses to test.

Why It Matters

An Android App That Works on One Device Is Not an Android App

The most common mistake in Android development is building and testing on a single device — typically a developer's own flagship phone — and assuming the result works everywhere. Android runs on thousands of device models with different screen sizes, RAM capacities, processor speeds, manufacturer UI customisations, and Android version distributions. An app that works perfectly on a Pixel can crash on a Samsung Galaxy A series device that represents a significant portion of your user base.

This fragmentation problem is manageable, but only if it's treated as a first-class design constraint rather than an afterthought. Responsive layout systems need to handle screens from 5 to 7 inches and multiple aspect ratios. RAM management matters on devices with 3GB rather than 12GB. Manufacturer UI skins — Samsung One UI, Xiaomi MIUI, OPPO ColorOS — apply their own rendering behaviour that can break assumptions made on stock Android.

Jetpack Compose and Android's modern architecture components — ViewModel, Room, WorkManager — provide the foundation for apps that work reliably across device diversity. Compose's declarative layout system adapts to screen dimensions without requiring separate layout files for each size class. Architecture components manage state correctly when the Android system destroys and recreates activities in response to configuration changes.

We build native Kotlin apps tested on a representative device matrix throughout development — not just at the end. The matrix covers the screen sizes, manufacturer skins, and Android versions that represent your actual target market, derived from Play Console data where available or industry distribution data for new apps. When a device-specific issue is found, it is fixed before the next build cycle rather than discovered by a user after launch.

What You Receive

Exactly What We Deliver

No vague deliverables. Every Android App Development engagement comes with a clear set of files, assets, and outputs.

Production Android Application

A fully built, tested, and Play Store-approved native Kotlin application covering the complete agreed scope. Delivered with full source code, unit and integration tests, and a documented architecture overview using Android Architecture Components.

Device Matrix Test Report

A written test report documenting the devices, Android versions, and manufacturer skins tested during development, with the results of each test run. This report provides evidence of the app's compatibility range for internal stakeholders and enterprise customers.

Security & Code Protection

ProGuard/R8 obfuscation configuration, Android Keystore integration for sensitive credential storage, and network security configuration enforcing certificate pinning where required. Security configuration is documented for any subsequent security review.

Firebase Cloud Messaging Setup

Fully configured FCM push notification integration with rich notification support, notification channel management for Android 8+, and delivery tracking. Notification templates are tested across Android versions and manufacturer skins before go-live.

Play Store Listing & Submission

Complete Play Store submission including feature graphic, screenshots for phone and tablet, keyword-optimised store listing copy, and content rating questionnaire. We manage the staged rollout configuration and monitor crash signals in the first 48 hours post-release.

Architecture Documentation

A technical document covering the project's architecture pattern — typically MVVM with Clean Architecture layers — Jetpack component selection rationale, API integration design, and dependency management. Any Android developer joining your team can orient quickly using this document.

Our Process

From Kickoff to Results in 4 Steps

A clear, structured process so you always know where things stand — no guessing, no surprises along the way.

Scope & Architecture

We define the feature set, target device range, and technical architecture — selecting the right Jetpack components and data layer patterns before any design or code begins.

Design & Prototype

Screens are designed in Figma following Material Design 3 conventions and tested as an interactive prototype with representative users before development begins.

Build & Test

Development runs in sprints with working APKs delivered throughout. We test on real devices across manufacturer skins — Samsung One UI, Pixel, and others — throughout the build, not just at the end.

Play Store Launch

We manage the Play Store submission process, configure staged rollout for risk mitigation, and monitor crash reports and ratings in the first two weeks after launch.

Common Situations We Fix

Problems We've Seen — and How We Prevent Them

These are real situations that come up. Here's how our process makes each one impossible.

App crashes on Samsung and mid-range devices but not in testing

Samsung One UI and other manufacturer skins apply rendering and memory management behaviours that differ from stock Android. We identify the specific failure mode through device-matrix testing on real hardware — not emulators — and apply the platform-specific handling required. Common fixes include manufacturer-specific lifecycle workarounds, memory pressure handling for low-RAM devices, and rendering path adjustments for non-standard GPU configurations.

App is slow and janky on devices older than two years

Jetpack Compose performance profiling using Android Studio's Layout Inspector and Systrace identifies the specific recomposition bottlenecks causing jank on lower-performance hardware. We apply remember optimisations, key stability annotations, and lazy column cell sizing patterns that reduce recomposition frequency — achieving smooth 60fps rendering on devices three or more years old.

Google Play has flagged the app for policy violations

We conduct a full policy compliance audit covering the current Play Store policy set — permissions justification, data safety declaration accuracy, ads policy, and sensitive content classification. Violations are categorised by severity and addressed in priority order. We draft the policy compliance response to Google's enforcement team and manage the appeal process through to resolution.

Background tasks stop running when the device enters battery optimisation

Android's battery optimisation system — Doze mode, App Standby, and manufacturer-specific battery management — aggressively restricts background work on many devices. We implement WorkManager with appropriate constraints and battery optimisation exemption request flows for genuinely critical background tasks. Each background task is categorised by urgency and scheduled using the appropriate WorkManager policy so it runs reliably without requiring the user to manually exempt the app.

Why It Works

What Makes Our Approach Different

We don't just deliver a project — we make sure it actually performs for your business after launch.

Reach the Majority of Smartphone Users

Android holds roughly 72% of global smartphone market share. For businesses targeting emerging markets, enterprise deployments, or consumer products outside the Apple ecosystem, Android is where the majority of your users live — and a native Android app is the right way to reach them.

Built for Device Diversity, Not Just Flagships

We test on a wide range of real Android devices — including mid-range handsets that make up the majority of users in most markets — throughout development. Responsive layouts, adaptive icons, and conditional logic for older API levels ensure the app works reliably for every user, not just those with the latest flagship.

Jetpack Compose: Fast and Maintainable

Jetpack Compose — Android's modern declarative UI framework — produces UIs that are faster to build, easier to maintain, and simpler to test than the XML-based approach it replaces. Apps built in Compose are better positioned for long-term maintainability as Google's tooling continues to invest in the ecosystem.

Enterprise-Ready Security Controls

Android's enterprise security APIs — managed profiles, device policy, encrypted storage, and certificate management — make it the platform of choice for corporate deployments. We implement these controls correctly when your use case requires them, including full compatibility with MDM platforms.
