Android App Development by Senior Native Engineers

Android App Development from Global One Digital ships native Kotlin and Jetpack Compose apps for B2B and consumer brands across the USA, EU and CIS. Modern architecture, REST or GraphQL backend integration, Play Store submission and ongoing maintenance — all delivered by senior engineers with shipped production apps in the portfolio.

What native Android development means in practice

Native means Kotlin (not Java legacy), Jetpack Compose for UI (not legacy XML layouts), proper architecture based on MVI or MVVM with clear separation of concerns, dependency injection via Hilt, and reactive flows via coroutines and StateFlow. The application performs well on mid-range Android devices, not just on flagship phones, and handles flaky network conditions gracefully because most Android users worldwide live with imperfect connectivity.

What our engagements typically include

Standard scope covers product discovery and feature scoping, custom UX and UI design (Material 3 or your design system), implementation by senior Kotlin engineers, REST or GraphQL backend integration, push notifications via FCM, deep linking, in-app purchases or subscriptions where applicable, analytics with Firebase or your tooling, crash monitoring (Crashlytics, Sentry), automated tests where they pay back, and Play Store submission with proper screenshots, descriptions and review responses.

Stack and tooling we work with

Kotlin with Jetpack Compose for new projects. Coroutines and StateFlow for async work. Hilt for dependency injection. Retrofit and OkHttp for networking. Room for local persistence. Coil for images. Ktor or Retrofit for networking. WorkManager for background jobs. CI on GitHub Actions or Bitrise. Distribution via Firebase App Distribution for internal testing, plus Play Console internal and closed testing tracks.

Realistic timelines

An MVP single-platform Android app ships in six to eight weeks. A production app with more screens, integrations and offline support takes ten to fourteen weeks. Apps with custom native modules, complex animations or significant local data work require sixteen weeks or more.

Maintenance after launch

Android updates roll out continuously and behaviour guidelines change every major OS release. Apps that go six months without maintenance start to feel dated and break in subtle ways on newer phones. Optional retainers cover OS update support, crash monitoring, performance tuning and feature additions at predictable monthly cost — usually one to four thousand dollars per month depending on app complexity.

Working with your team

For companies with internal mobile engineers we embed into the existing team and follow your code review process. For teams without Android experience in-house we hand off cleanly with documentation and runbooks, then optionally maintain the application long-term. Source code lives in your repository from day one.

Who this is designed for

SaaS companies adding native Android to a web product. Internal tools teams shipping field-staff applications for warehouse, logistics or inspection workflows. Consumer brands launching loyalty apps, content apps or marketplace experiences. Founders shipping MVPs that need a real native application to validate the idea, not just a clickable prototype.
