Android App Development Company: Android Application Development Services

Updated September 2026 · Written and maintained by the Progression Agency strategy team

Progression Agency is an Android application development firm that designs, builds, publishes and maintains Android apps for businesses across the United States and worldwide. A strong app developer for Android also plans for the long tail of screen sizes and OS versions, because the same release lands on very different phones and tablets. We build natively in Kotlin with Jetpack Compose or cross-platform with React Native and Flutter, test across the phones and tablets your customers actually use, and handle Google Play submission and launch marketing.

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. Titles vary. An Android application company usually sells the same core service as a firm calling itself an Android app company. An Android development agency may wrap design or marketing around it. Compare Android application companies on who writes the code and who answers after launch, not on the label.

Our Android application development services: an Android software development company for Kotlin apps

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. We take custom Android mobile app design and development as one project, because app design for Android depends on screen sizes and system navigation that designers and developers need to settle together.

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. Healthcare Android app development adds its own requirements on top of that: individual logins on shared tablets, automatic logoff, audit logs and limits on who can open patient records, all of which come from the HIPAA technical safeguards.

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. Google Play store development does not stop at launch, since every update is a new release that needs testing and a fresh pass through the console.

Comparing Android quotes: scope, charges and who builds it

Someone weighing an Android app development company in the USA against an Android app developer online is really comparing scope. A custom Android app development service should say which parts of the product are built in Kotlin, which are reused and what gets tested on physical devices.

Android app development charges follow that scope: screens, integrations, backend work and how many device and OS combinations are tested. Ask each candidate to describe its Android app development solution in those terms, so the quotes can be lined up item by item.

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. Either way, ask iOS and Android app developers to show both store builds of one product, because iOS and Android app development tend to diverge most around permissions, notifications and background work. A single iOS and Android app developer can cover a small app, but will struggle to test widely on both platforms alone.

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. The tools for Android app development listed below change often, so ask any vendor which versions it builds on and how it handles target API upgrades. Android mobile software development is also where the choice between a phone-only layout and a phone-and-tablet layout gets made, and it changes how many screens there are to design and test.

Software for Android app development, and who should own the accounts

The toolkit matters less to a buyer than who holds the accounts behind it. Android Studio covers code and first tests, Firebase Crashlytics reports crashes once real people are using the app, and Firebase Remote Config lets us change a setting or switch off a feature without publishing an update. At handover, the Play Console, the Firebase project and the source repository should sit under your company’s name, and the developer gets user access. Under Play App Signing, Google holds the app signing key and your team signs each bundle with an upload key, so settle who keeps that upload key before the first release.

Software for Android app development: the toolchain we use

Our default setup starts with Android Studio, Google’s official IDE for the platform, which brings together the editor, an emulator, a Gradle-based build system and lint checks that flag correctness, security, performance and accessibility problems before a release. Interfaces are written in Kotlin with Jetpack Compose.

After launch, Firebase Crashlytics reports crashes in real time so the team can see which stability issues to fix first, and Google Play’s pre-launch reports install uploads on test lab devices to look for stability, compatibility, performance and accessibility problems. Most serious teams use similar tools, so the list alone will not separate two vendors. Ask how often they ship builds and who reads those reports.

How much does Android app development cost?

At market rates, 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. Whatever Android application development price a proposal shows, ask which devices, OS versions and store requirements it covers, because those line items vary most between quotes. The cost of Android app development does not stop at launch either, because target API updates and testing on new OS versions recur for as long as the app stays on Google Play.

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. An Android app developer hire works best when someone on your side can review code and set priorities. Companies that want to develop an Android application without that in-house lead usually need project management from the vendor as well. Whichever Android app developer company you pick, ask for the name of the person who answers production issues after launch, since that is who you will deal with when something breaks.

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.

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. That makes the device matrix a line in the budget for mobile application development on Android, rather than a final check.

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. Google has announced that Firebase Test Lab shuts down on September 30, 2027 and points teams to the Developer Device Platform on Google Cloud, so test suites started today should be written to move across before that date.

Android app developer for hire vs an Android development team

Businesses that search for an Android app developer for hire usually need more than one person: application development for Android needs design, Kotlin engineering, device testing and Google Play publishing. Hire Android app developers individually for a small change to an existing app; use a team for a new product. For ongoing capacity see hire dedicated developers. Android TV application development is a clear example of team work, since it adds remote-control navigation and large-screen layouts to the usual device testing load.
