In an increasingly competitive digital landscape, maintaining a legacy Android app built with Java and XML-based UI can hold you back from taking advantage of the latest innovations. If your app is showing its age and struggling to keep up with modern user expectations, it might be time for an upgrade.
At DigitalJet, we specialize in helping businesses modernize their Android apps by migrating from outdated frameworks and languages to cutting-edge technologies, ensuring your app is more efficient, maintainable, and ready for the future.
Here’s how we can help you future-proof your Android app:
1. Migrate from Java to Kotlin: Unlock the Power of Modern Android Development
Kotlin is now the gold standard for Android. Beyond just being "modern," it offers structural safety features like Null-Safety that prevent the most common runtime crashes before they ever reach your users.
Kotlin has become the official language for Android development, and for good reason. It offers:
- Concise, expressive syntax that reduces boilerplate code
- Null-safety that prevents many common runtime errors
- Seamless interoperability with existing Java code while offering advanced features like coroutines for simplified asynchronous programming.
By migrating your app from Java to Kotlin, you’ll not only improve code quality but also enhance the productivity of your development team, enabling faster feature delivery, easier debugging, and greater scalability.
"Migrating to Kotlin typically reduces codebase volume by 25-30%, leading to faster debugging and significantly lower maintenance costs."
2. Switch from XML UI to Jetpack Compose: The Future of UI Design
Jetpack Compose is the declarative UI toolkit designed to simplify Android app development. It allows you to:
- Build UIs with less code and fewer bugs compared to traditional XML layouts
- Easily create dynamic, responsive UIs that adapt to different screen sizes and resolutions
- Streamline UI development by combining UI components and logic into a single, cohesive framework
With Jetpack Compose, you'll see not only reduced development time but also a more modern, fluid user experience that meets the expectations of today’s mobile users.
3. Architect for Success: Modernize Your App’s Architecture
If your legacy app is based on outdated architecture, now is the time to adopt modern patterns such as MVVM (Model-View-ViewModel) and Clean Architecture. These frameworks:
- Promote separation of concerns, making your app more modular and testable
- Enhance maintainability, allowing your development team to work on features or fixes without fear of breaking other parts of the app
- Make it easier to scale your app over time as you add new features and functionalities
With a cleaner, well-structured architecture, your app will be better equipped to evolve with your business needs.
4. Increase Performance and Stability
Upgrading to Kotlin, Jetpack Compose, and modern architecture patterns doesn’t just make your app more efficient to develop, it improves app performance too:
- Faster load times and smoother transitions with more efficient code
- Better memory management, leading to a reduced crash rate
- Enhanced compatibility with the latest Android versions and devices
Your users will enjoy a faster, more stable experience, which is essential to increasing retention rates and driving engagement.
5. Improved UX/UI Design: Bringing Your App into 2026
The world of mobile design is constantly evolving. We can help revamp your app’s user interface (UI) to ensure it aligns with modern design principles, including:
- Material You design for personalized, dynamic color themes
- Optimized UI for dark mode and high-contrast settings
- Responsive designs that look great on phones, tablets, and foldables
A fresh, user-friendly design will not only improve your app’s aesthetic appeal but will also boost user satisfaction and retention.
6. Adopt the Latest Android SDKs & Libraries
To stay competitive, your app needs to leverage the most recent tools and libraries that Android offers. Whether it’s integrating new Android APIs or adopting Jetpack libraries (like Navigation, Paging, or WorkManager), we ensure your app is:
- Up-to-date with the latest Android features and SDK versions
- More secure, by using libraries that are actively maintained
- Future-proofed to be compatible with upcoming Android versions
