Loading Images with Coil
Load and cache network images efficiently with Coil. Apply transformations (CircleCrop, RoundedCorners), handle placeholders and errors.
Why an Image Library?
Loading images from the internet is surprisingly complex:
- Download on a background thread
- Cache to disk and memory
- Decode efficiently (avoid OOM crashes)
- Show a placeholder while loading
- Handle errors (broken link, no network)
Coil handles all of this in one line of code.
What Is Coil?
Coil (Coroutine Image Loader) is a modern Android image loading library built for Kotlin and Coroutines.
- Lightweight — smaller than Glide or Picasso
- Kotlin-first with coroutine support
- Lifecycle-aware — cancels loads automatically
- Supports GIF, SVG, video frames
