Android App Development

An Android app from Rayo is engineered for the Play Store — with special attention to performance, background processing and battery efficiency. Whether it's a consumer product, an internal enterprise tool or a specialized hardware integration, we build with Android best practices from day one.

Our Android Development Standards

Kotlin and Jetpack Compose

We write modern Android in Kotlin with Jetpack Compose for new projects. The Android ecosystem moves fast and we keep up with it — using Google's recommended architecture components and following Material Design 3 guidelines.

Testing Across Real Devices

Android fragmentation is real. We test on a range of real devices across different manufacturers, screen sizes and Android versions. Emulators catch some problems. Real devices catch the rest.

Performance on Mid-Range Hardware

Not all your users have the latest Samsung Galaxy. We profile and optimise our apps to perform well on mid-range hardware — the reality for the majority of Android users globally.

Play Store Submission

We handle the Google Play Console setup, store listing, screenshots, content rating and review process. We're familiar with Play Store policy requirements and how to navigate them.

Frequently Asked Questions

Clear answers to common questions about our Android app development process.

How do you handle Android fragmentation?

Building for Android means designing for a fragmented ecosystem. We don't just build for the latest flagship devices; we ensure your application performs across a wide range of hardware, screen sizes and OS versions. We define a minimum SDK version that covers your target audience, use responsive layouts and density-independent units, test on real devices across manufacturers, and use compatibility libraries where needed. Fragmentation is manageable with the right approach.

Can you publish the app under our Google Play developer account?

Yes. We can publish directly to your Google Play Console account. You maintain full ownership and control of the app and all its data.

Can you migrate our existing Android app from Java to Kotlin?

Yes. We've done this for several clients. We typically migrate module by module rather than all at once, reducing risk and allowing the app to continue shipping updates during the transition.
