From GIFs to Lottie: Mastering Lottie Animations in Android with Jetpack Compose
Article Summary
Pavithra Chamod J from PickMe Engineering makes the case: if you're still using GIFs for Android animations, you're leaving performance and control on the table. Lottie animations offer vector-based crispness, runtime control, and smaller file sizes—but only if you know how to implement them properly.
This practical guide walks through implementing Lottie animations in Jetpack Compose, from basic setup to advanced runtime customization. The article compares GIFs versus Lottie across file size, scalability, and control, then demonstrates real-world patterns for loading, controlling playback, and dynamically theming animations.
Key Takeaways
- Lottie animations are vector-based, stay crisp at any scale, and offer full playback control
- Control speed, iterations, and pause/play state by driving progress with animateLottieCompositionAsState
- Load animations from res/raw locally or fetch dynamically from remote URLs with proper error handling
- Runtime customization lets you change colors and properties without exporting multiple JSON files
- Common pitfalls include large unoptimized JSONs, recomposition issues, and poor network delay handling
Lottie transforms animations from static assets into programmable UI elements that respond to app state, making them ideal for loaders, status transitions, and celebration moments in production Android apps.

Android teams often struggle with animation choices. GIFs are large files that look pixelated when you scale them up, while static images don't give users any sense of motion or feedback. Pavithra Chamod J's guide shows how to get past these limitations in production apps.
Use Lottie Compose by adding the lottie-compose dependency to your project. Load JSON animations from res/raw with rememberLottieComposition, then control playback using animateLottieCompositionAsState. This lets you pause, play, and change speed while the app is running.
Lottie animations take up less space than GIFs. They render sharply on any screen size because they're vector-based. You can also tie animations to different UI states like loading spinners, success screens, or celebration effects without needing to export multiple animation files.
