Example Concept: Implement lazy loading and pagination by fetching data in chunks rather than loading the entire data set at once. Use background threads for data processing to keep the UI responsive. For instance, in Android, you can use the Paging library to load data gradually, while in iOS, you can use Combine or GCD to perform background tasks. This approach minimizes memory usage and enhances the app's responsiveness by ensuring that only the necessary data is loaded and processed at any given time.
