Android migration
If your Android app is still on Java, it gets more expensive to maintain every year: it's increasingly hard to find developers willing to touch that code, and modern Android APIs and libraries assume Kotlin and Jetpack Compose.
What we do
Agent-assisted conversion with idiomatic refactoring (null-safety, coroutines, Compose) and characterization tests that prove behavior doesn't change. Rollout is gradual, module by module, leveraging Java/Kotlin interop — no need to freeze development while we migrate.
The agent writes, a senior engineer with 7 years of Android experience verifies every change, and the tests prove it.
Deliverables
- Java → Kotlin conversion verified module by module
- Idiomatic refactor (null-safety, coroutines, Jetpack Compose)
- Characterization tests guaranteeing behavioral equivalence
- Gradual rollout without blocking active development
How we work, milestone by milestone
Each migrated module is a fixed-price milestone: it's billed once the characterization tests confirm behavior hasn't changed.
FAQ
- Do I have to migrate the whole app at once?
- No. We migrate module by module, taking advantage of Kotlin and Java coexisting in the same project.
- How do I know behavior doesn't change?
- With characterization tests: we capture current behavior before touching the code and compare it after every change.
- Do I need to rewrite the UI in Compose right away?
- It's not required to migrate the logic to Kotlin, but we recommend it as a next step once the core is migrated.
