Our Android Development Services
Kotlin-first Android development, from custom apps and Compose UI to Google Play optimization and long-term support.
Custom Android App Development
Native Android development using Kotlin and Jetpack Compose. End-to-end delivery, including architecture, UI, API integration, Google Play submission, and post-launch iteration.
Jetpack Compose UI Development
Modern declarative UI with Jetpack Compose. New projects built natively in Compose; existing XML-based apps migrated incrementally, screen by screen, without full rewrites.
Android App Testing and QA
Unit testing (JUnit, Mockito), UI testing (Espresso, Compose Testing), and end-to-end testing on real devices across major manufacturers, not just emulators.
Google Play Submission
Full Google Play Console management, from store listing, screenshots, content rating, data safety section, and compliance with Google's policies. Post-launch ASO included.
Android App Migration
Migrate Java apps to Kotlin. Migrate cross-platform apps (React Native, Flutter, Ionic) to native Android when performance demands it. Legacy XML UI to Jetpack Compose.
Maintenance and Support
Bug fixes, Android version compatibility updates, security patches, and Google Play policy compliance. Performance monitoring via Firebase Crashlytics and Sentry.
Android Tech Stack and Expertise
What Our Android Developers Build
Consumer and Marketplace Apps
Social platforms, on-demand delivery, e-commerce, fitness, and media apps. Built with Material Design 3 for a polished, native Android experience. Optimized for the full range of Android devices — phones, tablets, foldables, and Chromebooks.
Enterprise and Workforce Apps
Field operations, inventory tracking, CRM tools, fleet management, and employee apps. Built with offline-first architecture (Room + WorkManager) for environments with unreliable connectivity. MDM compatibility and enterprise distribution via Managed Google Play.
Healthcare and Regulated Apps
Patient-facing apps, remote monitoring dashboards, medication trackers, and clinical tools. HIPAA-aware architecture with encrypted local storage, secure API communication, and integration with Google Fit / Health Connect for biometric data.
Fintech and Banking Apps
Mobile banking, payment apps, investment platforms, and expense management. Biometric authentication (fingerprint, face unlock), secure keystore for credentials, certificate pinning, and PCI-DSS-aware data handling.
IoT and Connected Devices
Apps that communicate with Bluetooth (BLE) hardware, smart home devices, wearables, and industrial sensors. We work with the Android Companion Device Manager, Bluetooth GATT profiles, and custom hardware protocols.
Why Companies Hire Android Developers From Tech Exactly
Our Android app developers work as an extension of your team, combining strategy with AI-driven workflows to speed up development. With global experience across 10+ geographies, we are GDPR-compliant and ensure smooth, timely collaboration.
Kotlin-First Development
Our Android developers write Kotlin as their primary language — not Java with Kotlin syntax. We use Kotlin-specific patterns: coroutines for async work, Flow for reactive streams, sealed classes for state management, and extension functions for clean APIs.
Jetpack Compose Production Experience
We've shipped production apps using Jetpack Compose — not just experimented with it. Our team builds fully Compose-based UIs with custom design systems, animations, and complex lazy lists. For existing apps, we do incremental Compose adoption alongside XML layouts.
Multi-Device Coverage
Android isn't just phones. We build for tablets, foldables, Chromebooks, Android Auto, and Wear OS. Responsive layouts that adapt across screen sizes and form factors using window size classes.
48-Hour Onboarding
From approval to first standup in 48 hours. Developer integrates into your Slack, Jira, and Git repos. No procurement delays.
Compliance-Aware Architecture
We build for regulated industries — healthcare (HIPAA), fintech (PCI-DSS), and enterprise (SOC 2). Security practices include encrypted storage, certificate pinning, ProGuard/R8 obfuscation, and runtime integrity checks.

I’m most impressed with Tech Exactly’s ability to understand our challenges and come up with options to resolve them
Tech Exactly takes the time to listen to us and offers us 3–5 different options to achieve the expected results.
With other vendors I’ve worked with, I have to spend a lot of time explaining the challenge to them, and sometimes, they still don’t understand it.

Frequently Asked Questions
A basic Android app (5-8 screens, standard Material Design UI, REST API) costs $15,000-$30,000. Medium-complexity apps with custom UI, background processing, and third-party integrations range from $30,000-$80,000. Enterprise apps with offline support, compliance requirements, and complex business logic can exceed $100,000. We provide detailed estimates after reviewing your requirements — contact us for a tailored quote.
An MVP typically takes 8-12 weeks. A full-featured app takes 4-6 months including design, development, testing, and Google Play submission. Jetpack Compose speeds up UI development significantly compared to traditional XML layouts, often reducing UI implementation time by 30-40%.
Build native Android if you need peak performance, deep hardware integration (Bluetooth, NFC, sensors), or if your user base is primarily Android. Go cross-platform (React Native or Flutter) if you need both iOS and Android simultaneously on a limited budget. We work with both approaches.
Yes. Kotlin and Java fully interoperate in the same project, so we migrate incrementally — class by class, module by module — while the app stays in production. Android Studio even has automated Java-to-Kotlin conversion for straightforward cases. We handle the manual refinement to use idiomatic Kotlin patterns (coroutines, sealed classes, data classes) rather than just syntactic conversion.
Yes. We build responsive layouts using window size classes that adapt across phones, tablets, Samsung foldables (Fold/Flip), and Chromebooks. For Wear OS, we build standalone watch apps and companion apps using Compose for Wear OS.
Kotlin is Google's recommended language for Android development since 2019. It's more concise (30-40% fewer lines of code), has built-in null safety (fewer crashes), and supports modern patterns like coroutines for async programming. Java is still supported and necessary for legacy codebases, but all new Android development at Tech Exactly is done in Kotlin. We maintain Java expertise for migration and legacy support projects.
Google frequently updates Play Store policies (target API level requirements, data safety declarations, permissions changes). We monitor policy updates, ensure your app meets current requirements, and handle the data safety section declaration. For apps collecting sensitive permissions (location, camera, health data), we prepare the permission declaration forms required by Google.
