Peacock Optimizes Streaming with Jetpack Compose
Article Summary
NBCUniversal's Peacock just proved that building for foldables isn't just about supporting bigger screens. It's about future-proofing your entire streaming experience.
Sa-ryong Kang and Miguel Montemayor from Google's Developer Relations team break down how Peacock migrated to Jetpack Compose to handle the explosion of Android form factors. With users increasingly watching on mobile and foldable devices, the streaming app needed a solution that could adapt without interrupting playback or causing visual glitches.
Key Takeaways
- Migrated to Jetpack Compose using WindowSizeClass API for seamless layout switching
- Users can unfold devices mid-stream with zero reloads or friction
- Same adaptive foundation extends to Android XR with minimal extra development
- Tested edge cases using Android Studio emulator across device permutations
Peacock's Compose migration enables instant transitions between screen sizes without stream interruptions while positioning them for spatial computing.
About This Article
Peacock needed to stream smoothly across many different Android devices, from phones to foldables to future XR platforms. The challenge was keeping quality high without reloads or visual glitches as screen sizes changed.
The team switched to Jetpack Compose and used the WindowSizeClass API to build layouts that adapt at specific viewport breakpoints. They paired this with Kotlin Coroutines and Flows to keep the UI responsive when the window size changed.
The app now works better across all device types. Users can start watching on a phone and pick up instantly on a larger unfolded screen with no reloads. This foundation also makes it easier to extend Peacock to Android XR later without major rework.
