Android App Development (Kotlin)
Native Android apps in Kotlin and Jetpack Compose — Material 3, modern, Play-Store-ready.
· Reviewed by senior engineers
01 What it is
What this service is
Native Android development means building an app using Google's first-party tools — Kotlin, Jetpack Compose, Android Studio — that compiles to a native APK / AAB and runs on the broad Android device fleet. It's the path to the smoothest performance, the deepest Google ecosystem integration (Google Wallet, Android Auto, Wear OS), and the highest Play Store ranking signals.
Devinsta ships Android apps in Kotlin with Jetpack Compose, Material 3, structured concurrency via Kotlin coroutines and Flow, and a modular Gradle setup.
02 What it's for
What it's for
Native Android is the right call when the app needs deep platform features (Google Wallet payments, App Bundles for region-specific distribution, Auto / Wear support), when device fragmentation matters (and you need fine-grained control over how the app behaves on a Samsung A-series vs a flagship Pixel), or when the audience skews heavily Android (typical in APAC, LATAM, Africa, India).
03 How to use it
How to engage devinsta
MVPs typically run 10–18 weeks. We share Play Internal Testing builds every two weeks, run a closed beta with real users from week 8, and submit to Play Store production with a phased rollout (5% → 20% → 50% → 100%) to catch regressions early.
04 How to deploy
How we deploy it
We use GitHub Actions or Gradle Build for CI. Every PR runs unit tests, instrumentation tests on Firebase Test Lab against a matrix of real devices, and builds an APK for internal testing. Releases go through Play Store with a staged rollout and crash-rate gating.
Observability uses Firebase Crashlytics, Firebase Performance Monitoring, and a backend trace pipeline (Datadog or Sentry) for distributed traces.

FAQ
Common questions
Do you support older Android versions?
We support the previous 4–5 major Android versions by default (typically API 26+), which covers ~95% of active devices. We adjust the floor based on your audience analytics.
What about Samsung, Huawei, or Xiaomi-specific features?
We test on a real device matrix via Firebase Test Lab — including Samsung S/A series, Xiaomi, Oppo, and other vendor ROMs. For Huawei (AppGallery distribution), we build a separate flavour using HMS where required.
Can you handle Play Store launch alongside iOS?
Yes — we routinely co-launch iOS and Android. The same engineering pod runs both, with shared design system, shared backend, and synchronised release dates.
