Is it possible to catch offline using universal image loader? If possible, how to use it? Using configs? How To Set Download Directory manually?
out of memory erroron load huge images :
my codes :
DisplayImageOptions defaultOptions = new DisplayImageOptions.Builder()
.cacheOnDisc(true).cacheInMemory(true)
.imageScaleType(ImageScaleType.IN_SAMPLE_INT)
.displayer(new FadeInBitmapDisplayer(300)).build();
ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(G.appConfigs.context)
.defaultDisplayImageOptions(defaultOptions)
.memoryCacheExtraOptions(480, 800) // default = device screen dimensions
.diskCacheExtraOptions(480, 800, null)
.memoryCache(new WeakMemoryCache())
.memoryCache(new LruMemoryCache(2 * 1024 * 1024))
.memoryCacheSize(2 * 1024 * 1024)
.discCacheSize(300 * 1024 * 1024)
.build();
ImageLoader.getInstance().init(config);
// END - UNIVERSAL IMAGE LOADER SETUP
ImageLoader imageLoader = ImageLoader.getInstance();
DisplayImageOptions options = new DisplayImageOptions.Builder().cacheInMemory(true)
.cacheOnDisc(true).resetViewBeforeLoading(true)
.showImageForEmptyUri(R.drawable.no_pic)
.showImageOnFail(R.drawable.load_failed)
.showImageOnLoading(R.drawable.img_thumb).build();
//download and display image from url
imageLoader.displayImage(imgURL, img, options);
how to resolve it ?
You can use the ImageLoaderConfiguration.Builder
class to customize disk caching. This includes the methods:
diskCacheExtraOptions()
diskCacheSize()
(in bytes).diskCacheFileCount()
diskCacheFileNameGenerator()
Or you can just use diskCache(DiskCache)
to provide a custom class for implementing offline caching.
From the example in the Configuration section of the wiki:
File cacheDir = StorageUtils.getCacheDirectory(context);
ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context)
.memoryCacheExtraOptions(480, 800) // default = device screen dimensions
.diskCacheExtraOptions(480, 800, 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
.diskCache(new UnlimitedDiscCache(cacheDir)) // default
.diskCacheSize(50 * 1024 * 1024)
.diskCacheFileCount(100)
.diskCacheFileNameGenerator(new HashCodeFileNameGenerator()) // default
.imageDownloader(new BaseImageDownloader(context)) // default
.imageDecoder(new BaseImageDecoder()) // default
.defaultDisplayImageOptions(DisplayImageOptions.createSimple()) // default
.writeDebugLogs()
.build();
