Android App Development
Quinoid's Android app development team builds apps for the most fragmented device ecosystem in mobile — from budget phones running older Android versions to flagship devices with foldable displays. Our India-based engineers design for that fragmentation from day one, testing across screen sizes, chipsets, and OS versions instead of treating Android as an afterthought to iOS. We write in Kotlin and use Jetpack Compose for modern, maintainable UI, while still supporting legacy Java codebases when a client needs us to extend an existing app rather than rebuild it. Because Android holds the dominant share of smartphones across India, Southeast Asia, and Latin America, it's usually the first release — not the second — for businesses targeting those markets at scale. We handle Play Store review, staged rollouts, and Play Console crash reporting as part of delivery, not as a separate handoff. Whether you need a consumer app built for millions of low-end devices or an enterprise tool distributed privately through Managed Google Play, our team ships Android apps that perform well outside flagship-device conditions.
Platform Features
Device & OS Fragmentation Testing
We test across a real matrix of screen densities, chipsets, and Android OS versions — not just the latest Pixel — so your app performs consistently on the budget and mid-range devices that make up most of the Android install base.
Jetpack Compose & Material Design UI
Our team builds UI in Jetpack Compose following Material Design guidelines, giving you an interface that feels native to Android users while staying easy to extend as your product roadmap grows.
Background Services & Battery Optimization
We implement WorkManager and foreground services correctly so background tasks like sync and notifications survive Android's aggressive battery-optimization and Doze mode restrictions without silently failing.
Play Store Release & Staged Rollouts
We manage Play Console setup, staged percentage rollouts, and crash/ANR monitoring as part of the build process, catching device-specific issues before they reach your full user base.
Delivery Process
Device & Market Scoping
We identify the Android OS versions, screen sizes, and device tiers your actual target market uses, since an app for urban India differs from one built only for flagship-device users.
Architecture & API Design
We define the app's MVVM architecture, local storage strategy, and backend API contracts before writing UI code, so the app stays testable as features get added.
Kotlin Development in Sprints
Engineers build in two-week sprints with working builds shared after each cycle, so you see real progress on a device rather than static designs.
Fragmentation & Performance Testing
Before release, we run the app across a device lab spanning different RAM tiers and Android versions to catch crashes that only show up on lower-end hardware.
Play Store Launch & Monitoring
We submit through Play Console with a staged rollout, then watch crash reports and Vitals dashboards closely during the first two weeks to catch issues early.
Proof
A reliable Android app built around user needs
A cleaner release path through QA and store readiness
A mobile product that integrates with your wider platform
Why Quinoid
Most agencies build their Android app to look right on the device sitting on their desk. Quinoid builds for the device sitting in your actual user's pocket — which, across India and similar markets, is rarely a flagship.
- We maintain a physical device lab covering low-RAM and older-OS Android devices, not just emulators on recent OS versions.
- Our Kotlin and Jetpack Compose engineers have shipped apps through Play Console's review process dozens of times, so launches rarely stall on policy rejections.
- We're based in India, the world's largest Android market, giving us direct day-to-day exposure to the device and network conditions your users face.

Frequently Asked Questions
How long does Android app development take?
A focused MVP typically takes 8-12 weeks; a fuller-featured app with backend integrations and offline support usually runs 16-24 weeks. Timelines shift based on third-party integrations and how much custom UI the design calls for.
Do you build in Kotlin or Java?
We build new apps in Kotlin with Jetpack Compose, Google's recommended modern stack. For existing apps with a Java codebase, we extend in Java or migrate incrementally rather than forcing a risky full rewrite.
Can you support older Android devices?
Yes — we define a minimum SDK target based on your actual user base and test against it directly. For markets like India, that often means supporting Android versions several releases behind the latest.
Do you handle Play Store submission?
Yes, we manage the entire Play Console process — listing setup, content rating, staged rollouts, and resolving any policy violations Google flags — so you don't have to navigate it alone.
