Kotlin is the language and Jetpack Compose is where new UI goes, but Views are still underneath most production apps, and interop between the two is a daily fact rather than a migration event. Compose earns its keep on screens that change state often; a stable list written years ago in XML rarely needs a rewrite to justify itself.
The device list is the job. API levels from your minSdk up to the newest release, screens from a small phone to a twelve-inch tablet, foldables that resize the window mid-session, and OEM builds that treat background work, notifications and permissions differently from stock Android. We take minSdk from your own Play Console install data and test on the manufacturers that dominate it, rather than on whatever is in a drawer.
Battery policy is the other half. Doze, App Standby buckets and aggressive OEM task killers make a background job a request rather than a promise — WorkManager for anything that must eventually run, a foreground service with a declared type and a written justification for anything the user has to watch happen, exact alarms only where policy allows. Play moves too: a target API level deadline every year, a Data safety form that has to match what the code actually sends, and declarations to fill in before a sensitive permission ships.

The Android reality
What you actually design around on Android
Reach is the reason to build on Android. Device fragmentation, battery policy and Play's own calendar are why it takes longer than a demo suggests — and all three are engineering decisions rather than surprises.
- minSdkSet from your install base
Fragmentation is a test plan, not a slogan
Screen sizes, densities, API levels and manufacturer skins multiply against each other. The answer is unglamorous: a minSdk taken from your own install data, layouts that respond to window size classes rather than device names, and a physical device set matching the manufacturers your users actually hold.
What it means in practice
- RTLChecked in CI
Locale changes more than the words
Android ships almost everywhere, and a locale switch moves text direction, date and number formats and font scaling underneath your layout. Long translations and right-to-left break interfaces far more often than they break logic, so we check both in CI instead of at the end.
What it means in practice
- AdaptiveWindow size classes
One language, several form factors
Phones, tablets, foldables, Wear OS, Android TV and Automotive share Kotlin but not a UI. Adaptive layouts and window size classes cover the first three; the rest are separate modules with their own input model — a watch has a rotary crown, a TV has a D-pad, and neither forgives a design drawn for a thumb.
What it means in practice
- IntentsGenuine system integration
System access iOS reserves for itself
Custom launchers, share targets, quick settings tiles, accessibility services, on-device ML Kit models, NFC and USB. It is a real advantage, and each one arrives with a runtime permission the user can revoke and a Play declaration you have to file for.
What it means in practice
- Target APIAnnual deadline
Play policy runs on a calendar
A new target API level deadline every year, after which updates stop being accepted for apps below it. Add Data safety declarations, permission-specific review, billing rules and periodic changes to what background work is allowed. An app nobody maintains quietly loses the ability to ship at all.
What it means in practice
- OEM skinsTested, not assumed
OEM behaviour is the long tail
Some manufacturers kill background processes far harder than stock Android, delay alarms, or bury notification settings in their own menus. No single flag fixes it — you make work resumable, keep state on disk, and test on the devices where it actually bites.
What it means in practice
Why Aryavos
How an Android build runs with us
from day one
No dashboard you never open, no team you never meet. This is how the work is organised and what you can hold us to.
Engineers who own the whole stack
In-house Android engineers working in Kotlin and Compose, plus the Gradle build, the CI and the Play Console release. Whoever writes a feature watches its crash rate afterwards.
Two-week sprints, working builds
A demo means an app on your own device through internal testing, not a screen recording. Scope can change at the sprint boundary — that is what the cadence is for.
Measured before it is optimised
Baseline profiles and startup traces, jank measured with the profiler rather than by feel, and download size watched per release. Most Android users are on hardware slower than a developer's phone.
Release metrics agreed up front
Crash-free sessions, ANR rate, cold start, install-to-first-action. Play Console reports most of them, and they decide whether a staged rollout continues or halts.
Support with a defined response
Named engineers, an agreed response window in your working hours, and an on-call arrangement where the app warrants one. Cover is scoped per engagement rather than promised around the clock.
Nothing depends on our accounts
The Play Console listing, the signing key under Play App Signing, the repository and the CI configuration are yours. Handover is a build another team can reproduce from a clean checkout.
What we take on for Android
New Android apps, end to end
Kotlin and Compose, a module layout that survives a second team joining, the Gradle and CI setup, and the Play Console release itself. You keep the repository and the signing arrangement rather than receiving a handover folder at the end.
Material 3 interface work
Screens designed in Material 3 with dynamic colour, checked at large font scales and in dark theme, and laid out against window size classes so a tablet or an unfolded device gets a real layout instead of a stretched phone one.
Kotlin and Compose migrations
Java code and View-based screens move incrementally — Compose inside a ComposeView next to existing fragments, Kotlin file by file, Gradle and AGP brought current so the build stops being the reason nothing changes. The app keeps shipping throughout.
Background work and integrations
WorkManager for jobs that must survive a reboot, foreground services with a declared type where the user has to see the work happen, FCM push with the notification permission handled properly, plus payments, maps and the internal systems the app has to stay consistent with.
Support, releases and policy upkeep
Staged rollouts watched against crash-free and ANR rates, target API level deadlines tracked before they bite, dependency and Gradle upgrades planned rather than deferred, and each annual Android release tested during the preview instead of after users find it.
How We Build
From Gradle project
to staged rollout
Seven steps, with the device list and the rollout treated as engineering work rather than as things that happen at the end.
- Typical first release3–4 months
- Sprint cadence2-week sprints
- Internal test buildsEvery sprint
- Production rolloutStaged by default
- Step 01
Scope and the device list
What the app has to do, and which devices it has to do it on. Your Play Console install data — or the market's, for a first release — sets minSdk, the manufacturers we test on, and whether tablets and foldables belong in this release or the next one.
- Step 02
Architecture and modules
Gradle module layout, a single-activity structure with a chosen navigation approach, unidirectional state in MVVM or MVI, Room or DataStore for persistence, and dependency injection wired once. All of it decided while changing it is still cheap.
- Step 03
Material 3 design
Designed in Material 3, with dynamic colour, dark theme, large font scales and window size classes settled while it is still a Figma file. Layouts are drawn for a size class rather than for one handset someone has on the desk.
- Step 04
Kotlin and Compose development
Two-week sprints, review on every pull request, and internal-testing builds through Play so you install the same artifact users will. Compose for new UI, interop where existing Views are doing fine, coroutines and Flow for anything asynchronous.
- Step 05
Testing across the matrix
Unit tests, Compose UI tests and Espresso where Views remain, running in CI on emulators — plus manual passes on physical devices from the manufacturers your install base actually uses, including one deliberately slow phone, a low battery and a bad network.
- Step 06
Play Console and release
Store listing, screenshots for every form factor you support, content rating, Data safety declarations matched to what the app really sends, permission declarations, and internal then closed testing tracks before anything reaches production.
- Step 07
Staged rollout and after
Production starts at a small percentage and is watched against crash-free sessions and ANR rate, with a halt if the numbers move the wrong way. Then the ongoing work: OS upgrades, target API deadlines, and the maintenance that keeps updates shippable.
