Jan 1, 2025

January 2025 performance summary for GetStream/stream-video-android. Focus was stabilizing the Jetpack Compose UI lifecycle and improving memory efficiency. What was delivered: lifecycle-aware Jetpack Compose UI improvements achieved by migrating coroutine scope usage to lifecycle-aware scopes and updating state collection to respect lifecycles. Specifically: 1) use compose coroutine scopes instead of the global scope for the demo project to ensure lifecycles are respected; 2) replace collectAsState with collectAsStateWithLifecycle to avoid updates when UI is not active. Impact: reduced memory leaks, fewer unnecessary recompositions, and more reliable UI behavior when the app moves to background. This work enhances stability and performance of the video UI and reduces crash surface in lifecycle transitions. Tech stack involved Kotlin, Jetpack Compose, coroutines, and lifecycle-aware components. Business value: improved stability, better user experience, and lower maintenance cost due to clearer, lifecycle-conscious state management.
