FAQ

Got questions?
We've got answers.

Everything you need to know about Android with Bytecode. Can't find what you're looking for? Our team is one message away.

Native Android or cross-platform?

Native suits apps needing top performance or deep device features. Otherwise cross-platform saves cost.

Can you update our old Java Android app?

Yes - we modernize it with Kotlin step by step.

Do you build Android apps with Kotlin and Jetpack Compose?

Yes. For new Android work we use Kotlin and Jetpack Compose by default, following Google's recommended app architecture, and we can introduce Compose gradually alongside existing XML-based screens.

How do you handle the wide range of Android devices?

We design layouts that adapt to different screen sizes, set sensible minimum OS versions based on your audience, and test on a mix of emulators and physical devices from several manufacturers.

Can you build for Android tablets, Wear OS or Android TV?

Yes. We adapt layouts and navigation for tablets and foldables, and build companion experiences for Wear OS or Android TV when they genuinely add value for your users.

Can you keep our app in line with Google Play requirements?

Yes. We keep target API levels current, handle permission and data safety declarations, and track policy changes so updates are less likely to be blocked when Google Play tightens its rules.

Native or cross-platform?

Cross-platform (React Native, Flutter, Ionic) suits most apps; native iOS and Android fit apps that need deep device features. We’ll recommend one.

Do you publish to the App Store and Google Play?

Yes - we handle builds, store listings and submission.

Can you build a Progressive Web App instead?

Yes, if your users don’t need app-store distribution or deep device access.

Can you take over an existing app?

Yes. We audit the code first, then fix, improve or rebuild.

Do you maintain apps after launch?

Yes - OS updates, bug fixes and new features.
