Android app development in Kotlin and Jetpack Compose
Hostlyx offers Android app development in Kotlin and Jetpack Compose. We test on budget, mid-range and flagship phones so the app stays fast on the devices your customers actually own, publish through Google Play Console under your account, and build and host the backend and admin panel. You get a fixed written quote before work starts.
Android runs on thousands of phone models, from entry-level handsets with little memory to flagship devices and foldables. In India most smartphones are Android, and many are budget models on patchy mobile data. An Android app that only works well on the developer's own phone loses those users quickly, so we design and test for the whole range.
We build in Kotlin with Jetpack Compose, Google's recommended language and interface toolkit. That gives a modern, maintainable codebase, Material Design that feels at home on Android, and access to everything the platform offers: background work, notifications, the camera, Bluetooth and home screen widgets. Where your existing systems hold the data, the app connects to them through a secure API.
Publishing runs through Google Play Console under your own developer account. We set up internal and closed testing tracks, complete the data safety form and content rating, and use staged rollouts so a new version reaches a small share of users before everyone. If crash reports rise, we pause the rollout, fix the problem and continue, so most customers never see the faulty build.
What is included
Kotlin and Jetpack Compose
A native Android codebase in Kotlin with Jetpack Compose interfaces, following Google's current architecture guidance so it stays easy to maintain and extend.
Testing across devices
The app is tested on budget, mid-range and flagship phones across Android versions and screen sizes, so performance holds up on modest hardware as well as new phones.
Light on data and storage
Small install size, cached content and sensible offline handling, so the app stays usable on slow connections and phones with limited storage and memory.
Device and platform features
Notifications, background sync, camera, Bluetooth, location and home screen widgets built properly and carefully, respecting Android battery limits and runtime permissions.
Play Console publishing
Store listing, data safety form, content rating and testing tracks set up under your account, then staged rollouts for each release to limit risk.
Backend and admin panel
The API, database and admin panel behind the app, built and hosted by us so the Android app and its server are maintained by one team.
Tools and platforms: Kotlin, Jetpack Compose, Android Studio, Coroutines, Room, WorkManager, Google Play Console, Firebase Cloud Messaging, Firebase Crashlytics

How we work
-
Scope and quote
We agree features, target devices and backend needs, then send a fixed written quote listing everything included before any work begins.
-
Design for Android
Material Design screens that respect Android navigation and adapt to small, large and foldable displays, approved by you before development.
-
Build and test
We build in Kotlin and Compose and share builds through Play Console internal testing, checking each one on a spread of real devices.
-
Play Store launch
We complete the listing, data safety and content rating, then release with a staged rollout and watch crash reports closely.
-
Ongoing updates
Google raises the required target Android version regularly. We update the app to meet it, so it stays listed and keeps working.
Questions people ask
How much does Android app development cost?
The cost depends on the number of screens, the device features involved, offline needs, the backend and admin panel, and integrations such as payments or maps. After a scoping call we send a fixed written quote that lists every feature included, so you can budget with certainty.
Will my Android app work on cheap phones?
Yes, if it is built for them, which is how we work. We keep the app small, cache data, limit heavy animation, and test on budget and older phones as well as new ones, so it stays smooth for customers who do not own flagship devices.
Should I choose Kotlin or a cross-platform framework like Flutter?
Kotlin is the better fit when the app relies on Android-specific hardware, background services or deep system features. If you need iOS too and the app is mainly screens, forms and data, Flutter or React Native usually costs less to build and maintain. We recommend one after scoping.
Do I need my own Google Play developer account?
Yes. The app should be published under a Google Play developer account in your business name, so you own the listing and its reviews. We help you register and verify the account, then handle publishing and updates for you.
Do I own the code for my Android app?
Yes. You own the source code, the designs and the Play Store listing. We hand over the code repository, and the app is published from your own Play Console account, so you are free to move it to another developer whenever you choose.
