When you need Android specialists

Six Android app problems native development solves.

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.

01

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.

02

Crashes after Android updates

Every new Android version or manufacturer skin breaks notifications, permissions or background tasks.

03

Play Store warnings and rejections

Target API deadlines, data-safety forms, permission declarations and policy strikes holding up releases.

04

Unusable without good internet

Field staff and rural customers lose work when the network drops because nothing is stored on the device.

05

Hardware features that don't work

Barcode scanning, Bluetooth printers, background GPS or camera capture that is unreliable on certain brands.

06

An ageing Java codebase

An old Java app with outdated libraries that nobody wants to touch, and every new feature takes weeks.

Native Kotlin development

Modern Android code that is quick to build on and easy to hand over.

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.

  • Kotlin, Jetpack Compose and Material 3 components
  • MVVM architecture with Hilt, coroutines and Flow
  • Retrofit and OkHttp for secure, fast API calls
  • Code reviews and documented modules for easy handover

Offline-first Android apps

Apps that keep working when the network doesn't.

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.

  • Local Room database with encrypted storage
  • Background sync and retries with WorkManager
  • Queued uploads for photos, signatures and documents
  • Small app size and low data use for budget plans

Location, camera and device features

Live GPS, scanning and printing that work across Android brands.

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.

  • Live location tracking with Google Maps and geofencing
  • CameraX capture, barcode and QR scanning with ML Kit
  • Bluetooth thermal printers, NFC and USB devices
  • Battery-optimisation handling on popular Android skins

Google Play publishing & ASO

From Play Console set-up to a staged rollout, handled for you.

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.

  • Play Console, signing keys and Android App Bundle set-up
  • Store listing, screenshots and keyword-focused ASO
  • Internal and closed testing tracks before production
  • Staged rollouts with Android vitals and crash monitoring

Testing and Android app security

Tested on real Android phones and secured before every release.

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.

  • Real-device testing across brands, sizes and Android versions
  • Unit and UI tests with JUnit, Espresso and Compose testing
  • Encrypted storage, certificate pinning and code obfuscation
  • Play Integrity API and secure payment gateway flows

FAQ

Android App Development Services — frequently asked questions

What do your Android app development services include?

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.

How much does Android app development cost in India?

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.

How long does it take to build an Android app?

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.

Do you use Kotlin or Java?

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.

Should I build native Android or a cross-platform app?

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.

Will you publish my app on the Google Play Store?

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.

How do you make Android apps work on cheap phones?

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.

Who owns the app and the source code?

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.

Do you provide Android app maintenance after launch?

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.
