Universal Image Loader for AndroidThis project aims to provide a reusable instrument for asynchronous image loading, caching and displaying. It is originally based on Fedor Vlasov's project and has been vastly refactored and improved since then.
Upcoming changes in new UIL version (1.9.3)
Android 2.0+ support

ImageLoaderConfiguration) is global for application.DisplayImageOptions) are local for every display task (ImageLoader.displayImage(...)).All options in Configuration builder are optional. Use only those you really want to customize.
See default values for config options in Java docs for every option.

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.

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

Also look into more detailed Library Map
// Create default options which will be used for every
// displayImage(...) call if no options will be passed to this method
DisplayImageOptions defaultOptions = new DisplayImageOptions.Builder()
...
.cacheInMemory(true)
.cacheOnDisk(true)
...
.build();
ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(getApplicationContext())
...
.defaultDisplayImageOptions(defaultOptions)
...
.build();
ImageLoader.getInstance().init(config); // Do it on Application start
// Then later, when you want to display image
ImageLoader.getInstance().displayImage(imageUrl, imageView); // Default options will be used
or this way:
DisplayImageOptions options = new DisplayImageOptions.Builder()
...
.cacheInMemory(true)
.cacheOnDisk(true)
...
.build();
ImageLoader.getInstance().displayImage(imageUrl, imageView, options); // Incoming options will be used

android:layout_width and android:layout_height parametersandroid:maxWidth and/or android:maxHeight parametersmemoryCacheExtraOptions(int, int) option)So try to set android:layout_width|android:layout_height or android:maxWidth|android:maxHeight parameters for ImageView if you know approximate maximum size of it. It will help correctly compute Bitmap size needed for this view and save memory.
.threadPoolSize(...)). 1 - 5 is recommended..bitmapConfig(Bitmap.Config.RGB_565) in display options. Bitmaps in RGB_565 consume 2 times less memory than in ARGB_8888..memoryCache(new WeakMemoryCache()) in configuration or disable caching in memory at all in display options (don't call .cacheInMemory())..imageScaleType(ImageScaleType.IN_SAMPLE_INT) in display options. Or try .imageScaleType(ImageScaleType.EXACTLY).ImageLoaderConfiguration.memoryCache(...)) you can use already prepared implementations.LruMemoryCache (Least recently used bitmap is deleted when cache size limit is exceeded) - Used by default
UsingFreqLimitedMemoryCache (Least frequently used bitmap is deleted when cache size limit is exceeded)LRULimitedMemoryCache (Least recently used bitmap is deleted when cache size limit is exceeded)FIFOLimitedMemoryCache (FIFO rule is used for deletion when cache size limit is exceeded)LargestLimitedMemoryCache (The largest bitmap is deleted when cache size limit is exceeded)LimitedAgeMemoryCache (Decorator. Cached object is deleted when its age exceeds defined value)WeakMemoryCache (Unlimited cache)ImageLoaderConfiguration.diskCache(...)) you can use already prepared implementations:UnlimitedDiscCache (The fastest cache, doesn't limit cache size) - Used by default
LruDiskCache (Cache limited by total cache size and/or by file count. If cache size exceeds specified limit then least-recently used file will be deleted)LimitedAgeDiscCache (Size-unlimited cache with limited files' lifetime. If age of cached file exceeds defined limit then it will be deleted from cache.)NOTE: UnlimitedDiscCache is pretty faster than other limited disk cache implementations.
DisplayImageOptions.displayer(...)) you can use already prepared implementations:RoundedBitmapDisplayer (Displays bitmap with rounded corners)FadeInBitmapDisplayer (Displays image with "fade in" animation)PauseOnScrollListener:boolean pauseOnScroll = false; // or true
boolean pauseOnFling = true; // or false
PauseOnScrollListener listener = new PauseOnScrollListener(imageLoader, pauseOnScroll, pauseOnFling);
listView.setOnScrollListener(listener);
http://anysite.com/images/image.png_230x460) then it doesn't mean this URL is used in requests. This is just "URL + target size", also this is key for Bitmap in memory cache.

If you use Universal Image Loader code in your application you should inform the author about it ( email: nostra13[at]gmail[dot]com ) like this:
Subject: UIL usage notification
Text: I use Universal Image Loader <lib_version> in <application_name> - http://link_to_google_play. I [allow | don't allow] to mention my app in section "Applications using Universal Image Loader" on GitHub.
Also I'll be grateful if you mention UIL in application UI with string "Using Universal Image Loader (c) 2011-2014, Sergey Tarasevich" (e.g. in some "About" section).
