Android App Modernisation and Kotlin Migration

Android app modernisation involves improving an existing application's code, architecture, dependencies, build process and testing so it is easier to maintain, develop and support.

Usually. I prefer an incremental approach where practical, improving the highest-risk areas while preserving proven functionality and allowing the application to continue developing throughout the work.

Yes. Java and Kotlin can coexist, allowing me to migrate suitable areas progressively and test each stage.

Yes. I can assess older Android applications and identify outdated dependencies, architecture, build configuration, APIs and other technical issues that are making the application harder to maintain.

Yes. I profile startup, memory, network, database and background activity to identify measurable performance improvements.

Yes. Where appropriate, existing Android interfaces can be migrated to Jetpack Compose incrementally rather than replacing the entire application interface at once.

Yes. I can review project dependencies, identify outdated or obsolete libraries and update them alongside any application changes required for compatibility.

I establish tests around critical workflows, use staged changes and releases where appropriate, and carry out QA across representative Android devices and versions.
