How do I implement image caching using local caching effectively?

Asked on Nov 02, 2025

Answer

Implementing image caching effectively in mobile applications involves storing images locally to reduce network requests and improve performance. This can be achieved using frameworks like Glide for Android or SDWebImage for iOS, which handle caching seamlessly.

Example Concept: Image caching in mobile apps typically involves using a library that automatically caches images in memory and disk. For Android, Glide or Picasso can be used, which handle caching and retrieval efficiently. On iOS, SDWebImage provides similar functionality, allowing images to be cached in memory and on disk, reducing the need for repeated network calls and improving app performance.

Additional Comment:

Ensure that the caching library is configured to use both memory and disk caching for optimal performance.
Consider the cache size and eviction policy to balance between performance and storage usage.
Test the caching behavior under different network conditions to ensure reliability.
Use placeholders for images while they are being loaded to improve user experience.
