Android App Development Services

BUILT FOREVERYSCREENSIZE

We build native Android apps in Kotlin and Jetpack Compose for consumer products and enterprise device fleets, tested across the range of phones, tablets and foldables your users actually own.

Kotlin and ComposeGoogle Play releasesDevice fleet support
01Our Approach

Android means thousands of different devices, so we design for the modest phone on a weak connection first and the flagship second.

02Overview

Native Android for every screen and budget

  • 01Kotlin and Compose
  • 02Google Play releases
  • 03Device fleet support

Native Android development covers apps written in Kotlin for phones, tablets, foldables and dedicated hardware, plus the Google Play work that goes with them. It is the right choice when your market is Android-heavy, when staff use company-issued or rugged devices, or when the product needs background work, Bluetooth, NFC or scanner hardware that calls for direct access to the platform.

We build with Jetpack Compose and Material Design, and structure the app around a single source of truth so state survives rotation, process death and poor connectivity. Layouts adapt to window size instead of assuming one phone shape. We test on low-memory devices and older Android versions as well as current flagships, because that is where most performance problems appear.

03What We Do

Capabilities, End to End

01
Jetpack Compose interfaces

Declarative screens following Material Design, with theming, dynamic color and accessibility support for TalkBack, font scaling and touch target sizes built into each component.

02
Adaptive layouts

Interfaces that respond to window size classes, so one app serves phones, tablets, foldables and ChromeOS without separate builds or clumsy stretched screens.

03
Offline and background work

Room for local storage and WorkManager for deferred sync, uploads and reminders that respect battery limits and still complete after the device restarts.

04
Google services integration

Google Maps, Google Pay, ML Kit, Firebase Cloud Messaging and Play Billing integrated with fallbacks for devices that ship without Google Play services.

05
Enterprise device support

Apps prepared for Android Enterprise management, including managed configurations, work profiles, kiosk mode and integration with barcode scanners on rugged handhelds.

06
Performance and app size

Startup time, frame rendering and memory profiled on real hardware, with R8 shrinking, baseline profiles and app bundles to keep downloads small and launches quick.

04In The App

Details Users Can Feel

Adaptive layout

One screen rearranged for phone, tablet and an unfolded device.

Background sync

Queued changes uploaded when the connection returns, even after a restart.

Material theming

Your brand colors applied through Material components and dynamic color.

Barcode scanning

Camera or hardware scanner input feeding directly into your workflow.

06How It Runs

From Kickoff to Launch

01
Scope the devices
02
Design with Material
03
Build and distribute
04
Staged rollout
01
Scope the devices

We agree on the minimum Android version, the screen sizes and the hardware the app must support, using your audience data or fleet inventory, and identify platform risks before design begins.

02
Design with Material

Screens are designed with Material components and your brand theme, including tablet and foldable layouts. We review an interactive prototype with you so navigation is settled before code is written.

03
Build and distribute

Builds reach your team through Firebase App Distribution or a Play internal track. Automated tests run on emulators and physical devices from several manufacturers, covering old and new Android versions.

04
Staged rollout

We complete the data safety form and store listing, then release to a small share of users first. Crash rates and vitals are watched at each step before the rollout widens.

08Who It Is For

Built for Teams Like Yours

FLAGSHIP
Most of your users or staff are on Android

Your market leans toward Android, or your drivers, technicians and warehouse teams carry company devices. The app has to run well on mid-range hardware, cope with patchy coverage and talk to scanners, printers or sensors. A web wrapper has already shown its limits.

09Questions

What buyers ask before they start

If yours is not here, ask us directly. The first conversation is free and useful whether or not we work together.

Follow your audience. If your users are in regions or industries where Android dominates, or the app runs on devices you issue to staff, start with Android. If early adopters and paying customers skew toward iPhone, start with iOS and add Android once the product is proven. When both matter from the first release and the screens are conventional, a shared React Native codebase is usually the more economical route.

We define a device matrix from your audience data that covers the main manufacturers, screen sizes, Android versions and at least one low-memory phone. Automated tests run against that matrix on a cloud device farm for every release candidate, and we test by hand on physical devices for anything involving cameras, Bluetooth or manufacturer-specific battery behavior. The matrix and results are shared with you.

Yes. Android is the usual platform for dedicated hardware, and we build for it directly. That includes support for Android Enterprise so your device management tool can install, configure and update the app remotely, lock task mode for single-purpose kiosks, and integration with the scanner and printer SDKs from hardware vendors such as Zebra and Honeywell. We ask for sample devices early so testing happens on the real thing.

Yes, and we do it gradually. Kotlin and Java compile side by side, and Compose screens can sit inside existing XML layouts, so there is no need to stop feature work for a rewrite. We start with an audit, raise the target SDK to meet current Play requirements, then convert the screens that change most often. Each step ships to users, which keeps the risk of any single release small.

The app is published from your own Google Play developer account, so you own the listing and the signing key enrollment. We set up internal, closed and production tracks, complete the data safety and content rating forms, and automate uploads from the pipeline. New accounts may face Google's testing requirements before production access, which we plan for. Releases go out in stages with Android vitals monitored throughout.
