How can I optimize image loading in a mobile app to improve performance? Pending Review
Asked on Feb 22, 2026
Answer
Optimizing image loading in a mobile app is crucial for enhancing performance and user experience. Techniques such as lazy loading, caching, and using efficient image formats can significantly reduce load times and improve app responsiveness.
Example Concept: Implement lazy loading by loading images only when they are about to be displayed on the screen. Use image caching libraries like Glide for Android or SDWebImage for iOS to store images locally, reducing the need for repeated network requests. Additionally, consider using modern image formats like WebP or HEIF, which offer better compression and quality, to further decrease loading times and bandwidth usage.
Additional Comment:
- Lazy loading can be implemented using RecyclerView in Android or UITableView in iOS.
- Ensure images are appropriately sized for the device to avoid unnecessary scaling.
- Use placeholders while images are loading to maintain a smooth UI experience.
- Profile your app's performance to identify bottlenecks related to image loading.
