Frequently Asked Questions

Questions about java to kotlin migration

Have specific technical requirements or platform questions? We answer honestly before any commitment.

Will migrating our Android app from Java to Kotlin cause downtime or freeze feature development?

No. Java and Kotlin have 100% two-way interoperability. We migrate your codebase incrementally module by module or screen by screen, allowing your team to ship new features without interruption.

What are the main business benefits of migrating from Java to Kotlin?

Kotlin reduces codebase size by 30–40%, virtually eliminates NullPointerExceptions (the #1 source of Android crashes), improves app performance, and significantly speeds up development velocity.

Can you modernize our UI to Jetpack Compose as part of the migration?

Yes. We often pair Java-to-Kotlin migration with declarative Jetpack Compose refactoring to replace cumbersome XML layouts and streamline UI maintenance.
