Android App Development

Native Android apps built with Kotlin and Jetpack Compose — covering the full fragmentation landscape and Google Play submission from development through launch.

What it is

Native Android development uses Kotlin and Google's Jetpack libraries (Compose, Room, WorkManager, Navigation) to build applications that run on Android devices with full access to the platform API, distributed via Google Play or enterprise sideloading.

What you get

  • Kotlin with Jetpack Compose for modern declarative UI
  • Room database for local persistence and offline support
  • WorkManager for reliable background task scheduling

Android development that survives the fragmentation problem

Android's diversity is its biggest development challenge. The test matrix covers thousands of device configurations, OS versions from Android 8 through 14, manufacturer customisations (Samsung One UI, MIUI, EMUI), and variable hardware capabilities. Developers who do not account for this ship apps that work on Pixels and break everywhere else.

We write Kotlin throughout with Jetpack Compose for UI, which produces type-safe, testable UI code with significantly less boilerplate than XML layouts. The Jetpack suite covers the common requirements: Room for local persistence, WorkManager for background tasks, CameraX for camera, Navigation component for multi-screen flows.

Google Play submission is included: signing keystore management, build variants for debug/staging/production, Play Console listing setup, internal/closed/open test tracks for staged rollout, and content rating questionnaires. We set up Play App Signing so Google manages the production key on your behalf.

Key capabilities

What we build for you

Each engagement is scoped to your requirements — these are the core capabilities we bring to the table.

CameraX for consistent camera access across devices

Material You design system implementation

Android Auto and Wear OS extensions

Extensive device and OS version compatibility testing

Google Play staged rollout and in-app update management

Our process

Discovery to deployment

A structured, engineering-led approach that moves from understanding your goals to a production system — with no handoff surprises.

Typical engagement

8–16 WEEKS

01

Discovery

We map your goals, constraints, and existing infrastructure. Scope is defined and success criteria agreed before any development begins.

Requirements workshopTechnical audit
02

Architecture

We design the technical approach, select the right tools, and produce a milestone-driven delivery plan with no ambiguity.

Stack selectionDelivery plan
03

Build

Iterative development with regular demos. Code reviews, test coverage, and documentation happen in parallel — not at the end.

Sprint cadenceCode review
04

Deploy

Production release with monitoring setup and handover documentation. We stay close during the first weeks post-launch.

Kotlin

We set a minimum SDK that covers 95%+ of active devices, use Jetpack libraries that abstract away OS version differences, and test on a device matrix that includes low-end, mid-range, and flagship hardware across Samsung, Google Pixel, and other manufacturers. Firebase Test Lab runs automated tests across the most common device configurations.

Jetpack Compose for all new projects. It is Google's direction, produces 40–60% less UI code, is more testable, and the tooling (Composable previews in Android Studio) is mature. XML layouts are maintained in existing codebases but we do not start new projects with them.

Google Play review is typically faster (hours to 3 days vs Apple's 1–7 days) and more automated. Policy violations are often caught after publication rather than before, which is a different risk profile. We review against Play policies during development and include Play Protect compatibility testing to reduce post-publish rejection risk.
