Introduction
Android Is Global, Diverse, and Always Changing
Android runs on an enormous range of devices: budget phones, flagship handsets, tablets, foldables, rugged field devices, wearables, TVs, and cars. Each Android release also changes behavior, and Google Play updates its requirements every year. A good Android app has to handle all of that.
As an Android app development company with deep experience in enterprise software, we build apps that perform across device tiers, meet current Play policy, and connect cleanly to the systems behind them. Our Android app development services cover consulting, UI/UX design, Kotlin and Compose engineering, API integration, QA, Play Store release, and ongoing upkeep, delivered by one accountable team.

Native Android vs cross-platform
Native Android or Cross-Platform? How to Decide
| Choose | When | Trade-offs |
|---|---|---|
| Native Android (Kotlin + Compose) | When: You need top performance, deep platform features, or Android-first users | Trade-offs: Separate iOS codebase if you also need iOS |
| Kotlin Multiplatform (shared logic) | When: You want shared business logic with native UIs on each platform | Trade-offs: Needs careful architecture |
| Flutter or React Native | When: You need iOS and Android from one UI codebase, fast | Trade-offs: Some advanced device features need native modules |
| Progressive web app | When: You need broad reach with light device access | Trade-offs: Limited device capabilities and store presence |
Quick guide
- Heavy background work, Bluetooth, camera, or sensors? Lean native.
- Android-first market or managed Android device fleet? Native Android is usually the right choice.
- Fast MVP for both platforms? Cross-platform may suit you better.
We'll recommend the best fit during discovery and tell you honestly if a different approach serves you better.
Google Play compliance and Android 16 readiness
How does Xcrino keep your app compliant with Google Play requirements?
Google updates its requirements every year, and an app that misses them can't ship updates. We treat compliance as a core part of Android development.
- Target API upgrades: since 31 August 2026, new apps and updates must target Android 16 (API level 36) or higher, with an extension available on request until 1 November 2026 (lower minimums apply to Wear OS, Android Automotive, TV, and XR apps).
- Visibility of older apps: existing apps must target API 35 or higher to remain available to new users on newer Android versions, so unmaintained apps lose installs quietly.
- 16 KB page size support: apps targeting Android 15 and higher must support 16 KB memory page sizes on 64-bit devices, which affects apps with native libraries and third-party SDKs.
- Android 16 behavior changes: adaptive layouts for large screens, predictive back navigation, and edge-to-edge display handling.
- Data safety and privacy disclosures: accurate Play Console declarations and policy review before release.
- Billing and permissions: compliance with Google Play's billing and sensitive-permission policies.
Last reviewed: October 2026. Policy details change each year. We verify current requirements with Google's official documentation at the start of every release cycle.
Devices, form factors, and performance
How does Xcrino handle Android device fragmentation and performance?
- Device fragmentation: we define a device and OS support matrix from your user analytics, then test on real low-end, mid-range, and flagship hardware.
- Large screens and foldables: adaptive layouts and window-size handling, so tablets and foldables get a proper experience. For apps targeting API 36, orientation and resizability restrictions no longer apply on wide displays.
- Beyond phones: other Android form factors such as Wear OS or Android TV can be scoped as a separate phase when your product calls for them.
- Performance engineering: startup time, memory, battery, and rendering performance, profiled with Android Studio tools and monitored with crash and performance reporting after launch.
- Accessibility: TalkBack support, contrast, and touch-target standards.

Cost and timeline
How Much Does Android App Development Cost?
Cost depends on factors you can influence:
- Scope and features: user roles, payments, real-time features, offline mode, and AI
- Design depth: custom UI, animations, and the number of screens
- Device and form-factor range: phones only, or tablets, foldables, wearables, and more
- Integrations: ERP, CRM, payment, and third-party APIs
- Back end and scale: data volume, users, and performance needs
- Security and compliance: regulated industries add requirements
- Post-launch needs: monitoring, annual target API upgrades, OS updates, and new features
How scope changes budget and timeline:
- MVP or simple app: phones only, a small set of core screens, and a simple back end, delivered in weeks
- Mid-complexity business app: phone and tablet layouts, several user roles, payments, and integrations, delivered over a few months
- Enterprise or AI-powered app: wide device coverage, several integrations, security review, and staged Play rollouts in phases
Budget beyond launch: Android apps need yearly upkeep for Play requirements and OS changes. After a free discovery call, we provide a scoped estimate with assumptions and risks.
Choosing a partner
What should you ask an Android app development company?
- Can you show published Android apps with store links and relevant case studies?
- Do you build new projects in Kotlin and Jetpack Compose, and why?
- How do you test across device tiers, OEMs, and Android versions?
- How do you handle Google Play target API and policy changes each year?
- Who owns the source code, signing keys, and Play Console account?
- How do you handle security, privacy, and user data?
- What happens after launch: monitoring, updates, and support?
Fit check
Is a native Android app the right choice for you?
A good fit when:
most of your users are on Android, your staff use managed Android devices, or the app depends on device features, background work, or offline use.
Not the best fit when:
you need iOS and Android at the same time on a limited budget, where Flutter or React Native is usually more efficient, or when a web app would meet the need.

Kotlin is Google's preferred language for Android and the right choice for most new projects. Java remains relevant for maintaining existing codebases. We build new apps in Kotlin and can modernize Java apps incrementally.
What is Jetpack Compose, and do you use it?
Jetpack Compose is Google's modern declarative toolkit for building native Android UI in Kotlin. We use it for new projects and can migrate existing XML-based apps in stages.
Should I build a native Android app or a cross-platform app?
Choose native Android when you need top performance, deep device features, or an Android-first audience. Choose Flutter or React Native for faster delivery across iOS and Android. We recommend an approach after discovery.
How much does it cost to develop an Android app?
Cost depends on scope, features, design depth, device range, integrations, security needs, and AI components. We provide a scoped estimate after a free discovery call.
How long does it take to build an Android app?
Timelines vary by scope. A focused MVP is measured in weeks, a business app with integrations in a few months, and an enterprise app in phased releases. We confirm a realistic timeline during discovery.
Do you handle Google Play submission and compliance?
Yes. We prepare signed builds, store listings, data safety declarations, staged rollouts, and policy checks, and we manage yearly target API upgrades so you can keep publishing updates.
What happens if my app doesn't target the latest Android API level?
Google Play requires new apps and updates to target a recent API level. Updates that miss the requirement can't be published, and older apps can become unavailable to new users on newer devices. We handle these upgrades as part of maintenance.
Can you build Android apps for tablets, foldables, and wearables?
Yes. We build adaptive layouts for large screens and foldables, and other form factors such as Wear OS or Android TV can be scoped as a separate phase.
Can you integrate the app with our ERP, CRM, or existing systems?
Yes. We build APIs and integrations that connect Android apps to ERP, CRM, payment, and third-party systems, with secure authentication and role-based access.
Can you add AI features to an Android app?
Yes. We add assistants, image and text recognition, recommendations, and automation to Android apps, running models on the device or in the cloud depending on privacy, latency, offline needs, and cost.
Can you build offline-capable Android apps?
Yes. We build Android apps that keep working without a connection, store data locally, and sync safely in the background once the device is back online, which suits field teams and low-connectivity regions.
Can you take over or modernize an existing Android app?
Yes. We audit the codebase, then refactor, migrate to Kotlin and Compose, upgrade the target API, and fix performance and security issues.
Who owns the source code and Play Console account?
Your contract sets out ownership of the source code, designs, signing keys, and Play Console assets before work starts, and everything it covers is handed over at the end of the project.
What support do you provide after launch?
We provide monitoring, bug fixes, OS and API upgrades, performance optimization, and new feature development.
