The short answerAndroid app development services cover planning, UX, Kotlin or cross-platform engineering, backend and API work, device testing, Google Play publishing and ongoing updates. Native Android (Kotlin and Jetpack Compose) gives the deepest hardware access and best performance; cross-platform reaches Android and iPhone from one codebase. A focused Android app commonly takes 3-5 months and, as a US planning range, costs roughly $50,000-$130,000 for a moderate business app.

Platform details reflect Android Developers and Google Play Console documentation as of September 2026. Cost ranges are planning figures, not quotes.

What does an Android app development company do?

An Android app development company plans, designs, engineers, tests, publishes and maintains apps for Android phones, tablets and other Android devices, usually together with the backend and admin tools behind them.

Kotlin — Native Android apps. Kotlin and Jetpack Compose..

Both — Cross-platform apps. React Native or Flutter..

Field — Rugged and field apps. Scanners, offline, kiosks..

Tablet — Tablet and foldable apps. Adaptive layouts..

Wear — Wear OS and TV. Companion experiences..

API — Backend and APIs. Accounts, data, admin..

Our Android application development services

Native Android development in Kotlin

We build native apps in Kotlin with Jetpack Compose, Google’s recommended modern toolkit, following Material Design 3 so the app feels at home on Android.

Cross-platform Android and iOS apps

When you need both platforms, cross-platform development in React Native or Flutter ships Android and iPhone from one codebase.

Enterprise, field and rugged-device apps

Android dominates warehouse scanners, field tablets and kiosks. We build offline-first apps with barcode scanning, signatures, photos and sync for crews and operations teams. See enterprise app development.

Android app modernization

Older Java or XML-layout apps can be migrated to Kotlin and Compose screen by screen, and updated to meet Google Play’s current target API level requirements.

Google Play publishing and launch

We handle Play Console setup, the data safety form, store listing, closed testing and release. New personal developer accounts must run a closed test with at least 12 testers for 14 continuous days before production access, which we plan into the schedule.

Native Android vs cross-platform — Choose native when Android-specific capability is the product; choose cross-platform when you also need iPhone and want one codebase.

Native Android or cross-platform?

Build native Android when the app relies on Android-specific capabilities, deep hardware integration or maximum performance. Build cross-platform when you also need an iPhone app and want lower build and maintenance cost.

Choosing an Android approach
Situation	Recommended approach
Android-only field or kiosk app	Native Kotlin
Consumer app for iPhone and Android	React Native or Flutter
Heavy camera, Bluetooth or sensor use	Native Kotlin, or cross-platform with native modules
Existing React web team	React Native
Highly custom branded UI	Flutter

How we build an Android app — Google Play requires apps to target a recent Android API level, so maintenance is part of every Android app’s lifecycle, not an optional extra.

How does app development on Android work?

Android apps are written in Kotlin (or Java) using Android Studio and the Android SDK, compiled into an app bundle, tested on emulators and real devices, and published through the Google Play Console. Cross-platform frameworks produce the same Android app bundle from shared code.

Android development toolkit
Layer	Tools
Language	Kotlin (Java for legacy)
UI	Jetpack Compose, Material Design 3
IDE	Android Studio
Architecture	ViewModel, Room, WorkManager, Hilt
Testing	JUnit, Espresso, Compose testing, Firebase Test Lab
Publishing	Google Play Console

Device matrix — Test. Samsung, Pixel, Motorola and more..

OS versions — Test. Current and recent Android..

Screen sizes — Test. Phones, tablets, foldables..

Accessibility — Test. TalkBack, font scaling..

Performance — Test. Startup time, jank, battery..

Network — Test. Offline and poor connections..

How much does Android app development cost?

As a US planning range, a simple Android app commonly costs $25,000-$60,000, a moderate business app $50,000-$130,000 and a complex app $130,000+. Adding iPhone roughly doubles native cost, which is why cross-platform is often better value.

Android app cost ranges (planning figures)
Scope	Typical range	Timeline
Simple Android app	$25,000-$60,000	2-3 months
Moderate business app	$50,000-$130,000	3-5 months
Complex / enterprise	$130,000+	5-9 months
Android + iOS cross-platform	$60,000-$160,000	4-6 months

Google Play charges a one-time $25 developer registration fee. See app development cost for more.

Hiring an Android app developer vs an Android development firm

A freelance Android developer can build a small app; an Android application development firm adds design, backend, QA across devices, Play Store compliance and long-term maintenance. See hiring app developers for how to decide.

How businesses search for Android developers — Android demand spans businesses hiring a firm and people asking how Android development works; both are answered here.

Google Play publishing requirements in 2026

Publishing on Google Play is more than uploading a build. These requirements shape the schedule of every Android project, and we plan for them from the first sprint.

Google Play requirements we plan for
Requirement	What it means for your app
Developer account	A one-time $25 registration fee and identity verification for the publishing organization
Android App Bundle	New apps are published as .aab files; Google Play generates optimized APKs per device
Target API level	New apps and updates must target an API level within one year of the latest major Android release
Closed testing (new personal accounts)	At least 12 testers opted in for 14 consecutive days before production access
Data safety section	A declaration of what data the app collects, shares and why, shown on the store listing
Account deletion	Apps that let users create accounts must let them request deletion in the app and on the web

Requirements summarized from the Google Play target API level policy and the Data safety guidance.

Testing across Android devices

Android runs on thousands of device models with different screen sizes, chipsets and manufacturer skins. Instead of testing everything, we test a device matrix built from your audience’s analytics.

Our Android test matrix
Test area	What we check
Screen sizes	Phones, small tablets and foldables, portrait and landscape
OS versions	Your minimum supported version through the latest release
Manufacturer skins	Samsung One UI, Pixel and at least one other major manufacturer
Performance	Cold start, scrolling, memory on a mid-range device
Permissions	Runtime permission flows, denial paths and background limits
Accessibility	TalkBack, font scaling and touch-target size

Firebase Test Lab and real devices

Automated UI tests run on Firebase Test Lab devices on every build, and real-device checks cover the models your users actually carry.
