Slow on budget phones
The app runs fine on the developer's phone but lags, freezes or drains battery on the entry-level handsets your customers actually use.
Most smartphones in India run Android, on everything from flagship phones to budget handsets with 3 GB of RAM. Our Android app developers build native apps in Kotlin and Jetpack Compose that start quickly, work on patchy networks and pass Google Play review — backed by 21 years of building software for Indian businesses.
When you need Android specialists
Android gives you the widest reach in India, but also the widest range of devices, OS versions and manufacturer quirks. These are the issues we fix most often.
The app runs fine on the developer's phone but lags, freezes or drains battery on the entry-level handsets your customers actually use.
Every new Android version or manufacturer skin breaks notifications, permissions or background tasks.
Target API deadlines, data-safety forms, permission declarations and policy strikes holding up releases.
Field staff and rural customers lose work when the network drops because nothing is stored on the device.
Barcode scanning, Bluetooth printers, background GPS or camera capture that is unreliable on certain brands.
An old Java app with outdated libraries that nobody wants to touch, and every new feature takes weeks.

Native Kotlin development
We write new Android apps in Kotlin, Google's recommended language, using Jetpack Compose for the interface and a clean MVVM architecture with Hilt dependency injection, coroutines and Retrofit. That structure keeps the code testable and readable, so adding features in year three is as quick as in month three — and any competent Android developer can pick it up.
Offline-first Android apps
Delivery riders, sales reps and technicians spend much of the day in basements, highways and villages with weak coverage. We design Android apps to save every action locally in a Room database first, sync in the background with WorkManager when a connection returns, and resolve conflicts safely. Users never lose an order, a photo or a signature because the signal dropped.
Location, camera and device features
Native Android gives full access to the device, but each manufacturer handles background location, battery saving and Bluetooth slightly differently. We use foreground services, the Fused Location Provider and CameraX, then test on the brands your users carry, so live tracking keeps running and a Bluetooth receipt printer connects first time.
Google Play publishing & ASO
Google Play has strict rules on target API levels, permissions, data safety and payments, and they change every year. We set up your Play Console, prepare the store listing and screenshots, complete the data-safety and content-rating forms, and release through internal, closed and production tracks with staged rollouts — so a bad build reaches a few users, not all of them.
Testing and Android app security
Android fragmentation means emulator testing is never enough. We test on a spread of real devices across screen sizes, Android versions and manufacturers, add automated tests with JUnit and Espresso, and run security checks before every release. Sensitive data is encrypted on the device, API traffic is pinned to your server, and Play Integrity helps block tampered or rooted installs where it matters.
What you get
Every Android app development project is handed over with the app live, the code documented and the accounts in your name.

FAQ
Our Android app development services cover requirements and device planning, Material Design UI/UX, native development in Kotlin and Jetpack Compose, backend APIs and a web admin panel, payment and map integrations, testing on real devices, Google Play publishing and ongoing maintenance. We can also upgrade or take over an existing Android app.
The cost of Android app development depends on the number of screens and user roles, offline needs, hardware features such as GPS or Bluetooth, integrations and the admin panel. After a short call we send a fixed, itemised quote for the first release, so you can see the cost of each feature and adjust the scope before work starts.
A focused Android app with an admin panel typically takes 8 to 14 weeks from scoping to Play Store launch. Simple apps can go live sooner; apps with offline sync, live tracking or several user roles take longer. You see a new APK on your own phone every week throughout development.
New apps are written in Kotlin with Jetpack Compose, which Google recommends for Android development. We still maintain and extend Java apps, and can migrate an older Java codebase to Kotlin gradually, module by module, so releases continue while the code is modernised.
Choose native Android when most of your users are on Android, when you need heavy hardware use, background location or top performance on low-end phones. If you need iPhone users from day one on a tight budget, a Flutter or React Native app may be better value. We explain the trade-offs for your specific app.
Yes. We set up or use your Play Console account, prepare the listing, screenshots, privacy policy and data-safety form, and release through testing tracks before a staged production rollout. If Google raises a review issue, we fix it and resubmit as part of the project.
We set performance budgets for start-up time, memory and app size, test on entry-level devices from popular brands, use baseline profiles and image optimisation, and keep heavy work off the main thread. Offline storage and small downloads also help users on limited data plans.
You do. For custom Android app development the source code, designs, app signing keys and Play Console account belong to you. We keep the code in a repository you control and hand over documentation at every major release, so you are free to work with us, an in-house team or another vendor later.
Yes. Google requires apps to target a recent Android API level every year, and new Android versions change permissions and background rules. Our monthly maintenance plans cover these updates, crash and ANR fixes, security patches and new features, with response times agreed in writing.
