#  Universal Image Loader for Android This project aims to provide a reusable instrument for asynchronous image loading, caching and displaying. It is originally based on [Fedor Vlasov's project](https://github.com/thest1/LazyList) and has been vastly refactored and improved since then.  ## Features * Multithread image loading * Possibility of wide tuning ImageLoader's configuration (thread executors, downlaoder, decoder, memory and disc cache, display image options, and others) * Possibility of image caching in memory and/or on device's file sysytem (or SD card) * Possibility to "listen" loading process * Possibility to customize every display image call with separated options * Widget support Android 2.0+ support ## Downloads * **[universal-image-loader-1.8.6.jar](https://github.com/nostra13/Android-Universal-Image-Loader/raw/master/downloads/universal-image-loader-1.8.6.jar)** (library; contains *.class files) * **[universal-image-loader-1.8.6-sources.jar](https://github.com/nostra13/Android-Universal-Image-Loader/raw/master/downloads/universal-image-loader-1.8.6-sources.jar)** (sources; contains *.java files) * **[universal-image-loader-1.8.6-javadoc.jar](https://github.com/nostra13/Android-Universal-Image-Loader/raw/master/downloads/universal-image-loader-1.8.6-javadoc.jar)** (Java docs; contains *.html files) * **[universal-image-loader-1.8.6-with-sources.jar](https://github.com/nostra13/Android-Universal-Image-Loader/raw/master/downloads/universal-image-loader-1.8.6-with-sources.jar)** (library with sources inside; contains *.class and *.java files)<br />_Prefer to use this JAR so you can see Java docs in Eclipse tooltips._ * **[universal-image-loader-sample-1.8.6.apk](https://github.com/nostra13/Android-Universal-Image-Loader/raw/master/downloads/universal-image-loader-sample-1.8.6.apk)** (sample application) Latest snapshot of the library - **[here](https://github.com/nostra13/Android-Universal-Image-Loader/tree/master/sample/libs)** ## Documentation* * Universal Image Loader.

Include library **Manual:** * [Download JAR](https://github.com/nostra13/Android-Universal-Image-Loader/raw/master/downloads/universal-image-loader-1.8.6-with-sources.jar) * Put the JAR in the **libs** subfolder of your Android project or **Maven dependency:** ``` xml <dependency> <groupId>com.nostra13.universalimageloader</groupId> <artifactId>universal-image-loader</artifactId> <version>1.8.6</version> </dependency> ``` #### 2. Android Manifest ``` xml <manifest> <uses-permission android:name="android.permission.INTERNET" /> <!-- Include next permission if you want to allow UIL to cache images on SD card --> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> ... <application android:name="MyApplication"> ... </application> </manifest> ``` #### 3. Application class ``` java public class MyApplication extends Application { @Override public void onCreate() { super.onCreate(); // Create global configuration and initialize ImageLoader with this configuration ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(getApplicationContext()) ... .build(); ImageLoader.getInstance().init(config); } } ``` ## Configuration and Display Options * ImageLoader **Configuration (`ImageLoaderConfiguration`) is global** for application. * **Display Options (`DisplayImageOptions`) are local** for every display task (`ImageLoader.displayImage(...)`). ### Configuration All options in Configuration builder are optional. Use only those you really want to customize.<br />*See default values for config options in Java docs for every option.* ``` java // DON'T COPY THIS CODE TO YOUR PROJECT! This is just example of ALL options using. File cacheDir = StorageUtils.getCacheDirectory(context); ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context) .memoryCacheExtraOptions(480, 800) // default = device screen dimensions .discCacheExtraOptions(480, 800, CompressFormat.JPEG, 75, null) .taskExecutor(...) .taskExecutorForCachedImages(...) .threadPoolSize(3) // default .threadPriority(Thread.NORM_PRIORITY - 1) // default .tasksProcessingOrder(QueueProcessingType.FIFO) // default .denyCacheImageMultipleSizesInMemory() .memoryCache(new LruMemoryCache(2 * 1024 * 1024)) .memoryCacheSize(2 * 1024 * 1024) .memoryCacheSizePercentage(13) // default .discCache(new UnlimitedDiscCache(cacheDir)) // default .discCacheSize(50 * 1024 * 1024) .discCacheFileCount(100) .discCacheFileNameGenerator(new HashCodeFileNameGenerator()) // default .imageDownloader(new BaseImageDownloader(context)) // default .imageDecoder(new BaseImageDecoder()) // default .defaultDisplayImageOptions(DisplayImageOptions.createSimple()) // default .writeDebugLogs() .build(); ``` ### Display Options Display Options can be applied to every display task (`ImageLoader.displayImage(...)` call). **Note:** If Display Options wasn't passed to `ImageLoader.displayImage(...)`method then default Display Options from configuration (`ImageLoaderConfiguration.defaultDisplayImageOptions(...)`) will be used. ``` java // DON'T COPY THIS CODE TO YOUR PROJECT! This is just example of ALL options using. DisplayImageOptions options = new DisplayImageOptions.Builder() .showImageOnLoading(R.drawable.ic_stub) // resource or bitmap .showImageForEmptyUri(R.drawable.ic_empty) // resource or bitmap .showImageOnFail(R.drawable.ic_error) // resource or bitmap .resetViewBeforeLoading(false) // default .delayBeforeLoading(1000) .cacheInMemory(false) // default .cacheOnDisc(false) // default .preProcessor(...) .postProcessor(...) .extraForDownloader(...) .imageScaleType(ImageScaleType.IN_SAMPLE_POWER_OF_2) // default .bitmapConfig(Bitmap.Config.ARGB_8888) // default .decodingOptions(...) .displayer(new SimpleBitmapDisplayer()) // default .handler(new Handler()) // default .build(); ``` ## Usage ### Acc
