How can I optimize image loading to improve app performance on low-end devices?
Asked on Jan 17, 2026
Answer
Optimizing image loading is crucial for enhancing app performance, especially on low-end devices. This involves using efficient image formats, lazy loading techniques, and caching strategies to minimize memory usage and improve rendering times.
Example Concept: To optimize image loading, employ lazy loading to defer loading images until they are needed, use efficient image formats like WebP for reduced file size, and implement caching mechanisms to store images locally. On Android, libraries like Glide or Picasso can manage these optimizations, while iOS developers can use SDWebImage or native caching techniques. These strategies reduce memory consumption and improve scrolling performance on low-end devices.
Additional Comment:
- Consider using vector graphics (e.g., SVG) for simple images to reduce file size.
- Implement image resizing to match the display size and avoid loading unnecessarily large images.
- Use placeholder images during loading to improve user experience.
- Profile memory usage and app performance using tools like Android Profiler or Xcode Instruments.
