Pagination helps your app load data in small chunks instead of all at once. This keeps the app smooth and responsive, aiming for 60 frames per second (fps) so scrolling feels natural. It also reduces memory use because only a few items are in memory at a time, which saves battery life.
Load data asynchronously on background threads to avoid blocking the main UI thread. Use RecyclerView with efficient adapters to recycle views and reduce layout work. Prefetch the next page of data before the user reaches the end to avoid waiting. Avoid heavy processing during scrolling to keep animations smooth.
Pagination itself adds minimal code size. However, libraries for pagination (like Paging 3) add some kilobytes but improve user experience greatly. Since data loads on demand, startup time is faster because the app does not fetch or render all data immediately.
On Android, pagination often uses RecyclerView with the Paging 3 library. On iOS, developers use UITableView or UICollectionView with Combine or async/await for data loading. Both platforms recommend loading data in chunks and recycling views for performance. Android requires careful thread management; iOS uses Grand Central Dispatch or Swift concurrency.
Both Google Play and Apple App Store require apps to be responsive and not freeze during data loading. Pagination helps meet this by loading data smoothly. Ensure your app handles network errors gracefully and does not crash when loading pages. Follow platform UI guidelines for loading indicators and user feedback during pagination.
Your app might be loading all data at once on the main thread, causing a freeze. You may not be using pagination or background threads. Check if data fetching blocks UI and if RecyclerView or list views recycle views properly. Implement pagination to load data in smaller chunks asynchronously.
