Custom Android app development
Native apps built in Kotlin from discovery to Play Store launch, with architecture chosen for your feature list, expected traffic and the team that will maintain the code later.
Jetpack Compose UI
Material Design interfaces built with Jetpack Compose, adaptive layouts for phones, foldables and tablets, plus dark mode and accessibility that holds up under TalkBack testing.
Java to Kotlin migration
Move a legacy Java and XML app to Kotlin and Compose screen by screen, removing crash-prone code while your existing users keep receiving regular updates.
Backend, API and Firebase integration
Connect your app to REST or GraphQL APIs, Node.js backends, Firebase Auth, Firestore and Cloud Messaging, with offline caching through Room so it works on weak networks.
AI features on Android
Add LLM-powered chat, smart search, image recognition or document scanning using cloud AI APIs or on-device ML Kit models, with clear controls for running cost and privacy.
Play Store release and maintenance
We prepare store listings, handle Play Console setup, staged rollouts and policy reviews, then keep the app current with OS updates, SDK target changes and crash fixes.
Android apps built for the devices your users actually own
- Ecommerce and loyalty apps
- On-demand booking and delivery apps
- Healthcare and assessment apps
- Field service and inventory apps
- Classifieds and marketplace apps
- Internal tools for tablets and rugged devices
Ecomsolver provides Android app development for founders and product teams who need a native app that runs well on budget phones, flagship devices and tablets alike. Android's reach is wide, but so is its fragmentation: screen sizes, manufacturer skins, aggressive battery optimizers and older OS versions all change how your app behaves. We plan for that from the first sprint, so the app you approve in a demo is the app your customers get.
Our engineers write modern Kotlin with Jetpack Compose for UI, coroutines for background work and a clean architecture that the next developer can pick up without a rewrite. We integrate the services buyers ask for most: Firebase, payments, maps, push notifications, offline sync and on-device or cloud AI features. Every build goes through automated tests and a CI/CD pipeline before it reaches the Play Console.
Already have an Android app that crashes, drains battery or still runs on Java and XML layouts? We audit it, fix the urgent issues first, then migrate screens to Kotlin and Compose in stages without freezing your release schedule. You keep full code ownership, and we sign an NDA before you share anything.

We fix it, fine-tune it, then add AI and automation.
Most clients come to us with something already running: a store that is slow, an app that crashes, code nobody wants to touch. We stabilise it first, then add the AI features that save time and earn money.
Fix
A code and infrastructure audit of your mobile app product, then the fixes that matter most.
- Bugs, crashes and broken integrations
- Security patches and outdated versions
- Code nobody can maintain
Fine-tune
Make it fast, stable and easy to change, without a risky rewrite.
- Speed, caching and database tuning
- Tests, CI/CD and monitoring
- UX fixes where users get stuck
Add AI & automation
Practical AI built into the mobile app product you already have.
- AI search and assistants over your own data
- Content, document and support automation
- AI agents that work with your tools
From first call to launch, with no surprises.
Clear milestones, weekly demos and a fixed price agreed before any work starts.
Discovery and scope
We review your idea or existing app, rank features by priority, choose the minimum Android version to support and deliver a written fixed quote with milestones.
UX and UI design
Clickable Figma prototypes following Material Design, checked on real screen sizes so navigation, forms and checkout flows feel natural to Android users.
Agile development
Two-week sprints in Kotlin with a demo build at the end of each, shared through Firebase App Distribution so you can test on your own phone.
Testing and QA
Unit, UI and manual tests across a mix of devices and OS versions, plus performance checks for startup time, memory use and battery drain.
Launch and support
We publish to Google Play with a staged rollout, monitor crashes and reviews, and stay on for updates, new features and yearly target SDK changes.

Android App Development: frequently asked questions
Ask us on WhatsApp. A real person replies, usually within minutes during working hours.
Ask on WhatsAppHow much does Android app development cost?
Android app development cost depends on the number of screens, user roles, backend work, third-party integrations such as payments or maps, and how many devices and OS versions you need to support. A simple app with a few screens costs far less than a marketplace with an admin panel and real-time features. After a free consultation we send a written fixed quote broken into milestones, so there are no open-ended hourly bills.
How long does it take to build an Android app?
A focused first version with core features usually takes a few months, depending on scope and how quickly feedback and content arrive. Larger apps with custom backends, admin dashboards and many integrations take longer. We share a milestone timeline with the quote and show working builds every week, so you always know where the project stands.
Should I build a native Android app or a cross-platform app?
Choose native Kotlin if your app depends heavily on device hardware, background services, Bluetooth, complex animation or Android-specific features such as home screen widgets. Choose Flutter or React Native if you need iOS and Android at the same time from one codebase on a tighter budget. We explain the trade-offs for your feature list during the consultation and recommend the option that fits.
Will you publish the app on Google Play for me?
Yes. We set up or use your Play Console account, prepare the listing, screenshots, privacy policy details and data safety form, and run internal, closed and production testing tracks. If Google flags a policy issue, we fix it and resubmit. The developer account stays in your company's name so you keep control of the app.
Can you take over and fix an existing Android app?
Yes. We start with a code and crash-log audit, list the urgent problems and estimate the fix. Common work includes resolving crashes on specific devices, meeting the target SDK level Google Play requires, replacing deprecated libraries and moving Java code to Kotlin in stages. We sign an NDA before you share the code.
What happens after the app launches?
We offer post-launch support plans covering crash monitoring, bug fixes, Android OS and SDK updates, security patches and new features. Google requires apps to target recent API levels every year, so ongoing maintenance protects your listing. You choose the level of support you need and can change it as the app grows.
