Logo Universal Image Loader

UIL aims to provide a powerful, flexible and highly customizable instrument for image loading, caching and displaying. It provides a lot of configuration options and good control over the image loading and caching process.

Project News

27.11 UIL celebrates 3 years of development :)

  • #1 of Android libraries for loading and caching images
  • #1 of Android libraries on GitHub (according to gitrep)
  • #3 of Java repositories on GitHub (according to gitrep)

Upcoming changes in new UIL version (1.9.4+)

  • Memory Cache redesign
  • Video file thumbnail support via file:///sdcard/video.mp4
  • New API: DisplayImageOptions.targetSize(ImageSize)
  • HTTP cache support
  • Consider BitmapFactory.Options.inBitmap
  • Time-to-live option for files in LruDiskCache

Features

  • Multithread image loading (async or sync)
  • Wide customization of ImageLoader's configuration (thread executors, downloader, decoder, memory and disk cache, display image options, etc.)
  • Many customization options for every display image call (stub images, caching switch, decoding options, Bitmap processing and displaying, etc.)
  • Image caching in memory and/or on disk (device's file system or SD card)
  • Listening loading process (including downloading progress)

Android 2.0+ support

Usage

Acceptable URIs examples

"http://site.com/image.png" // from Web
"file:///mnt/sdcard/image.png" // from SD card
"file:///mnt/sdcard/video.mp4" // from SD card (video thumbnail)
"content://media/external/images/media/13" // from content provider
"content://media/external/video/media/13" // from content provider (video thumbnail)
"assets://image.png" // from assets
"drawable://" + R.drawable.img // from drawables (non-9patch images)

NOTE: Use drawable:// only if you really need it! Always consider the native way to load drawables - ImageView.setImageResource(...) instead of using of ImageLoader.

Simple

// Load image, decode it to Bitmap and display Bitmap in ImageView (or any other view 
//	which implements ImageAware interface)
imageLoader.displayImage(imageUri, imageView);
// Load image, decode it to Bitmap and return Bitmap to callback
imageLoader.loadImage(imageUri, new SimpleImageLoadingListener() {
	@Override
	public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
		// Do whatever you want with Bitmap
	}
});
// Load image, decode it to Bitmap and return Bitmap synchronously
Bitmap bmp = imageLoader.loadImageSync(imageUri);

Complete

// Load image, decode it to Bitmap and display Bitmap in ImageView (or any other view 
//	which implements ImageAware interface)
imageLoader.displayImage(imageUri, imageView, options, new ImageLoadingListener() {
	@Override
	public void onLoadingStarted(String imageUri, View view) {
		...
	}
	@Override
	public void onLoadingFailed(String imageUri, View view, FailReason failReason) {
		...
	}
	@Override
	public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
		...
	}
	@Override
	public void onLoadingCancelled(String imageUri, View view) {
		...
	}
}, new ImageLoadingProgressListener() {
	@Override
	public void onProgressUpdate(String imageUri, View view, int current, int total) {
		...
	}
});
// Load image, decode it to Bitmap and return Bitmap to callback
ImageSize targetSize = new ImageSize(80, 50); // result Bitmap will be fit to this size
imageLoader.loadImage(imageUri, targetSize, options, new SimpleImageLoadingListener() {
	@Override
	public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
		// Do whatever you want with Bitmap
	}
});
// Load image, decode it to Bitmap and return Bitmap synchronously
ImageSize targetSize = new ImageSize(80, 50); // result Bitmap will be fit to this size
Bitmap bmp = imageLoader.loadImageSync(imageUri, targetSize, options);
