Jetpack Compose: Dive in to Strengths and Weaknesses

Jetpack Compose: Dive in to Strengths and Weaknesses

By SuriDevs  May 08, 2025

Jetpack Compose, developed by Google, represents a modern and declarative approach to building Android UI. Launched as part of Android Jetpack, Compose replaces the traditional XML-based UI system with Kotlin-based code, making UI creation more seamless and intuitive.

What is Jetpack Compose?

Jetpack Compose is Android's modern toolkit for building native UI. It simplifies and accelerates UI development on Android by using a declarative programming model. Instead of imperatively manipulating UI components, you describe what your UI should look like based on the current state, and Compose takes care of the rest.

Strengths of Jetpack Compose

1. Declarative UI Paradigm

Compose adopts a declarative approach where you define your UI as a function of state. This means less boilerplate code and a more straightforward way to build and update UIs dynamically.

2. Kotlin-First

Built entirely in Kotlin, Compose leverages Kotlin's concise syntax and powerful features like coroutines, extension functions, and lambdas, making it more expressive and safer than XML.

3. Less Boilerplate

Traditional Android UI development involves lots of XML layouts and findViewById calls. Compose eliminates much of this boilerplate, allowing developers to build UIs directly in Kotlin.

4. Live Preview and Tooling

Android Studio provides excellent tooling support for Compose, including live preview, interactive mode, and better debugging capabilities.

5. Composable Functions

UI components in Compose are just functions (composables), making them easy to test, reuse, and compose together to build complex UIs.

6. Animation Support

Compose has built-in APIs for animations that are simple yet powerful, enabling smooth and performant animations with minimal code.

Weaknesses of Jetpack Compose

1. Learning Curve

For developers used to the imperative XML-based approach, switching to a declarative paradigm requires a mindset shift and time to learn new concepts.

2. Library Maturity

While stable, Compose is still relatively new compared to the traditional View system. Some third-party libraries and components may not have Compose equivalents yet.

3. Build Times

In some cases, projects using Compose may experience longer build times, especially as the project grows in size.

4. Backward Compatibility

Compose requires Android API level 21 (Lollipop) or higher, which may limit its use in apps targeting very old devices.

5. Ecosystem Transition

Many existing Android libraries and tools are built around XML views. Integrating these with Compose (via interop) can sometimes be cumbersome.

Conclusion

Jetpack Compose represents a significant step forward in Android UI development, offering a modern, efficient, and enjoyable way to build user interfaces. While it comes with a learning curve and some ecosystem challenges, its benefits—such as reduced boilerplate, better tooling, and Kotlin-first design—make it a compelling choice for new Android projects. As the ecosystem matures, Compose is likely to become the standard for Android UI development.

Whether you're starting a new project or considering migrating an existing one, Jetpack Compose is definitely worth exploring!
