#  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](https://www.gitrep.com/search?utf8=✓&omni_search=&public_tags%5B%5D=android&description=&search=true&sort=star_count&commit=Search)) * **#3** of Java repositories on GitHub (according to [gitrep](https://www.gitrep.com/search?utf8=✓&omni_search=&public_tags%5B%5D=Java&description=&search=true&sort=star_count&commit=Search)) **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 ## Downloads * **[universal-image-loader-1.9.3.jar](https://github.com/nostra13/Android-Universal-Image-Loader/raw/master/downloads/universal-image-loader-1.9.3.jar)** * **[universal-image-loader-1.9.3-with-sources.jar](https://github.com/nostra13/Android-Universal-Image-Loader/raw/master/downloads/universal-image-loader-1.9.3-with-sources.jar)** (for Eclipse) * [](https://play.google.com/store/apps/details?id=com.nostra13.universalimageloader.sample) [](http://chart.apis.google.com/chart?chs=300x300&cht=qr&chld=|1&chl=https%3A%2F%2Fplay.google.com%2Fstore%2Fapps%2Fdetails%3Fid%3Dcom.nostra13.universalimageloader.sample) [<img src="http://mobway.in/image/apk.png" height="45px" />](https://github.com/nostra13/Android-Universal-Image-Loader/raw/master/downloads/universal-image-loader-sample-1.9.3.apk) ## [Documentation](https://github.com/nostra13/Android-Universal-Image-Loader/wiki) * **[Quick Setup](https://github.com/nostra13/Android-Universal-Image-Loader/wiki/Quick-Setup)** * **[Configuration](https://github.com/nostra13/Android-Universal-Image-Loader/wiki/Configuration)** * **[Display Options](https://github.com/nostra13/Android-Universal-Image-Loader/wiki/Display-Options)** * [Useful Info](https://github.com/nostra13/Android-Universal-Image-Loader/wiki/Useful-Info) - Read it before asking a question * [User Support](https://github.com/nostra13/Android-Universal-Image-Loader/wiki/User-Support) - Read it before creating new issue * [Sample project](https://github.com/nostra13/Android-Universal-Image-Loader/tree/master/sample) - Learn it to understand the right way of library usage * [ChangeLog](https://github.com/nostra13/Android-Universal-Image-Loader/blob/master/CHANGELOG.md) - Info about API changes is here ## Usage ### Acceptable URIs examples ``` java "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 ``` java // Load image, decode it to Bitmap and display Bitmap in ImageView (or any other view // which implements ImageAware interface) imageLoader.displayImage(imageUri, imageView); ``` ``` java // 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 } }); ``` ``` java // Load image, decode it to Bitmap and return Bitmap synchronously Bitmap bmp = imageLoader.loadImageSync(imageUri); ``` ### Complete ``` java // 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) { ... } }); ``` ``` java // 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 } }); ``` ``` java // 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); ``` ## Load & Display Task Flow  ## Applications using Universal Image Loader **[MediaHouse, UPnP/DLNA Browser](https://play.google.com/store/apps/details?id=com.dbapp.android.mediahouse)** | **[Prezzi Benzina (AndroidFuel)](https://play.google.com/store/apps/details?id=org.vernazza.androidfuel)** | **[ROM Toolbox Lite](https://play.google.com/store/apps/details?id=com.jrummy.liberty.toolbox)**, [Pro](https://play.google.com/store/apps/details?id=com.jrummy.liberty.toolboxpro) | [Stadium Astro](https://play.google.com/store/apps/details?id=com.astro.stadium.activities) | [Chef Astro](https://play.google.com/store/apps/details?id=com.sencha.test) | [Sporee - Live Soccer Scores](https://play.google.com/store/apps/details?id=com.sporee.android) | **[EyeEm - Photo Filter Camera](https://play.google.com/store/apps/details?id=com.baseapp.eyeem)** | [PhotoDownloader for Facebook](https://play.google.com/store/apps/details?id=com.giannz.photodownloader) | **[Topface - meeting is easy](https://play.google.com/store/apps/details?id=com.topface.topface)** | **[reddit is fun](https://play.google.com/store/apps/details?id=com.andrewshu.android.reddit)** | **[Diaro - personal diary](https://play.google.com/store/apps/details?id=com.pixelcrater.Diaro)** | [WebMoney Keeper Mobile](https://play.google.com/store/apps/details?id=ru.webmoney.keeper.mobi
