Technologies Native Android apps

Native Android apps

Android app development for customer products, internal tools and field operations.

Q: Do you use Kotlin or Java for Android development at QalbIT?

For new projects we use Kotlin as the primary language, as it is modern, concise and fully supported by Google. For existing apps built in Java, we can maintain the current codebase and gradually refactor critical parts to Kotlin over time where it makes sense.

Q: What kinds of Android apps do you typically build?

We build customer-facing Android apps, internal and field operations tools, companion apps for SaaS and web platforms, and modern replacements for legacy Android applications. Many of these apps integrate with backends, payment providers, maps, notifications and internal systems.

Q: Can you take over an existing Android app built by another team?

Yes. We usually start with a structured code and architecture review to understand how the current app is built, identify risks and quick wins, then stabilise critical issues. After that we can plan new features, refactors and a realistic roadmap without throwing away everything that already works.

Q: How do you handle Android device and OS fragmentation?

We plan for fragmentation from the start – defining minimum supported OS versions, testing on a representative set of devices and using modern Android libraries that handle many edge cases. For features that behave differently on certain versions or manufacturers, we implement guarded fallbacks and monitor issues using real-world crash and performance data.

Q: Can you integrate the Android app with our existing backend and APIs?

Yes. Most Android projects we deliver rely on existing backends or APIs. We review your current endpoints, authentication and rate limits, then design a stable integration layer using libraries such as Retrofit/OkHttp and local caching. If your backend is a bottleneck, we will suggest pragmatic improvements or a phased backend update.

Q: How long does it take to build an Android app MVP?

Timelines depend on scope, design depth, number of user roles and integrations. A focused MVP with clear flows can often be delivered in roughly 8–14 weeks after discovery. Larger, multi-module apps or complex integrations will take longer and are typically planned as phased releases.

Q: Do you help with Google Play publishing and release management?

Yes. We help you configure or use your existing Google Play Console account, set up app signing, internal testing tracks, staging and production releases. We prepare builds, app metadata, screenshots and release notes, and guide you through review and rollout best practices.

Q: How do you approach performance, security and offline behaviour in Android apps?

We focus on efficient networking, local caching and background work management so the app remains responsive even on slower networks. On security, we enforce HTTPS, protect sensitive data, follow best practices for authentication and token handling and avoid storing secrets in the app. For offline requirements, we design clear sync rules and user feedback rather than relying on ad-hoc behaviour.

Q: How do you price Android app development and ongoing maintenance?

For well-defined Android scopes we usually provide a fixed-price proposal with milestones. For longer-term products, evolving roadmaps or combined Android + backend work, we recommend a monthly or dedicated team model. In all cases we aim for transparent estimates tied to scope, complexity, integrations and the level of post-launch support you need.

QalbIT builds native Android apps using Kotlin and the modern Android ecosystem. We focus on stable performance across real devices, robust offline behaviour where needed and tight integration with your backend and internal systems.

Android development overview

Native Android development for serious products and operations

We recommend native Android when your app is business-critical, needs deep device integrations or must perform reliably across a wide range of Android hardware.

When Android with QalbIT makes sense

You have an Android-heavy user base and need the best possible performance and device support.
Your app depends on deeper device features such as background services, sensors, hardware integrations or complex offline behaviour.
You are modernising an existing Java-based Android app and want to move cleanly to Kotlin and the latest Android guidelines.
You need a partner comfortable with both product UX and the realities of Android fragmentation and deployment.

Outcomes we typically target with Android work

Stable, predictable Android apps that work well across common devices and OS versions.
Modern Kotlin codebases that are easier to maintain, extend and test.
Clean integration with backends, APIs, auth systems and analytics.
A clear release and update process for Play Store and private distributions.

Where it makes sense, we may still complement native Android with cross-platform code or shared backends – but the core experience remains tailored to Android.

What we build with Android

Android development capabilities across customer and internal apps

We focus on Android apps that carry real business value – core product experiences, operations tools and companion apps for platforms you already run.

Customer-facing Android apps

Customer apps

Consumer and B2B apps for booking, ordering, account management, dashboards and self-service workflows built natively for Android.

Internal & field operations apps

Field tools

Apps for internal teams or field staff to capture data, manage routes, inspections, deliveries or service visits – often with offline and background sync.

Companion apps for SaaS & platforms

Companion apps

Android apps that extend your existing SaaS, ERP or web portals with mobile access, push notifications and on-the-go workflows.

Modernisation of legacy Android apps

Modernisation

Reworking older Java or legacy-architecture apps into modern Kotlin-based Android applications that are faster and easier to support.
