Native Android apps designed, engineered and taken through Google Play review to a live, production listing.
Jetpack Compose interfaces, Play Console internal and closed testing, Data Safety declarations, target API compliance and staged rollouts — managed end to end.

Android app development is building an app for Android devices, typically in Kotlin with Jetpack Compose, and publishing it to Google Play as an Android App Bundle through the Play Console. Before production release, Google requires an accurate Data Safety declaration, a current target API level, justified permissions, and — for new personal developer accounts — a period of closed testing.
| Languages & frameworks | Kotlin, Jetpack Compose, Java where legacy code exists. |
|---|---|
| Tooling | Android Studio, Google Play Console, Firebase, Android vitals. |
| Play Console account | One-off $25 registration fee, held in your company's name; organisations must complete identity verification. |
| Closed testing requirement | New personal developer accounts must run closed testing with testers before applying for production access. |
| Publishing format | Android App Bundle (AAB) — APK uploads are no longer accepted for new apps. |
| Common rejection reasons | Inaccurate Data Safety form, unjustified sensitive permissions, outdated target API, misleading store listing. |
Android app development is building for the Google ecosystem — phones, tablets and foldables — usually in Kotlin with Jetpack Compose, then distributing through the Google Play Console as an Android App Bundle.
Google Play has its own gates: an accurate Data Safety form, a current target API level, permissions you can justify, and testing requirements that new developer accounts must clear before production access. Getting these wrong delays launch by weeks.
Android also means device fragmentation. We test across screen sizes, OS versions and manufacturer skins rather than assuming a Pixel is representative of what your customers hold.
Every engagement is built around measurable commercial impact — from revenue and leads to retention, efficiency and operational scale.
Modern native Android built on Google's current toolkit, ready for future OS releases.
Adaptive layouts and device testing across screen classes, OS versions and manufacturer skins.
Accurate Data Safety declarations, justified permissions, target API compliance and UK GDPR alignment.
Google sign-in, Play Billing, Firebase, Maps, push messaging and Wear OS where relevant.
Internal, closed and open testing tracks, then staged production rollouts you can halt if needed.
Firebase analytics plus Android vitals — crash rate, ANRs and performance monitored after every release.
Products where Android reach matters more than Apple's spend-per-user advantage.
Customer bases that skew Android, especially outside major cities.
Apps failing Google's target API requirements and at risk of being hidden from new users.
Rugged-device apps with scanning, offline sync and kiosk or managed-device deployment.
MVP definition, device targets, permissions review and the Play policies that apply to your category.
Material-aligned design tested on real device sizes before engineering starts.
Sprint builds shipped to the internal testing track for stakeholder use.
Closed testing where required, Data Safety completed, then production review and release.
Percentage rollouts, vitals monitoring and a planned release cadence.
Tell us what the app needs to do and we'll come back with a scoped feature list, a realistic timeline to App Store and Google Play approval, and an itemised cost — including what it costs to run, not just to build.
Modern Android apps are built in Kotlin, usually with Jetpack Compose for the interface, developed in Android Studio. Java is still used where legacy code exists.
You need a Google Play Console account, an Android App Bundle, a complete store listing, an accurate Data Safety declaration and a current target API level. New personal developer accounts must also complete a period of closed testing before applying for production access.
A one-off registration fee of $25. Organisation accounts require identity verification. The account stays in your company's name and ownership.
It is Google's mandatory declaration of what data your app collects and shares and how it is protected. It must match what the app actually does — inaccurate declarations are a common cause of rejection and removal.
Closed testing is a release track where a defined group of testers use the app before it can go to production. Google requires new personal developer accounts to complete it, and it is good practice for every launch.
Common causes are inaccurate Data Safety declarations, sensitive permissions without a clear justification, outdated target API levels, misleading store listings and policy breaches in categories such as finance and health.
Yes. Android fragmentation means testing across screen sizes, OS versions and manufacturer skins — a Pixel is not representative of what most customers actually hold.
Yes. We can take an existing build, bring it up to current target API and policy requirements, prepare the listing and manage the submission and staged rollout.
