Universal-Image-Loader: OutOfMemory Error

Question

I am using universal-image-loader-1.6.2.jar (Latest one). I am trying to Download and cache that images using this library. I have 47 images to be downloaded from server, total of 5.22 Mb.My Maximum images are of dimension are 720X480 and size around 143kb. It goes well till 40-41 images after that it gives error

I have seen and implemented suggestion about OOM on git-hub. I followed them still i am getting error. Here is my code

if (android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED))
        cacheDir=new File(android.os.Environment.getExternalStorageDirectory(),"neongall");
    else
        cacheDir=context.getCacheDir();
    if(!cacheDir.exists())
        cacheDir.mkdirs();

    ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context)
    .threadPoolSize(3)
    .threadPriority(Thread.NORM_PRIORITY - 1)
    .memoryCache(new WeakMemoryCache())
    .denyCacheImageMultipleSizesInMemory()
    .offOutOfMemoryHandling()
    .discCacheExtraOptions(720, 480, CompressFormat.JPEG, 75)
    .discCache(new UnlimitedDiscCache(cacheDir)) // You can pass your own disc cache implementation
    .discCacheFileNameGenerator(new HashCodeFileNameGenerator())
    .imageDownloader(new URLConnectionImageDownloader(120 * 1000, 120 * 1000)) // connectTimeout (5 s), readTimeout (20 s)
    .defaultDisplayImageOptions(DisplayImageOptions.createSimple())
    .enableLogging()
    .build();
    //Initialize ImageLoader with created configuration. Do it once on Application start.
    imageLoader.init(config);


    options = new DisplayImageOptions.Builder()
    .cacheOnDisc()
    .imageScaleType(ImageScaleType.IN_SAMPLE_POWER_OF_2)
    .displayer(new RoundedBitmapDisplayer(10))
    .build();

Thanks in advance.

First of all your configuration:

ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context)
.threadPoolSize(3) // equal to default value
.threadPriority(Thread.NORM_PRIORITY - 1) // equal to default value
.memoryCache(new WeakMemoryCache())
.denyCacheImageMultipleSizesInMemory()
.offOutOfMemoryHandling()
.discCacheExtraOptions(720, 480, CompressFormat.JPEG, 75)
.discCache(new UnlimitedDiscCache(cacheDir)) // You can pass your own disc cache implementation
.discCacheFileNameGenerator(new HashCodeFileNameGenerator()) // equal to default value
.imageDownloader(new URLConnectionImageDownloader(120 * 1000, 120 * 1000)) // connectTimeout (5 s), readTimeout (20 s)
.defaultDisplayImageOptions(DisplayImageOptions.createSimple()) // equal to default value
.enableLogging()
.build();

is equal to

ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context)
.memoryCache(new WeakMemoryCache())
.denyCacheImageMultipleSizesInMemory()
.offOutOfMemoryHandling()
.discCacheExtraOptions(720, 480, CompressFormat.JPEG, 75)
.discCache(new UnlimitedDiscCache(cacheDir))
.imageDownloader(new URLConnectionImageDownloader(120 * 1000, 120 * 1000))
.enableLogging()
.build();

DON'T COPY CONFIGURATION FROM README!

Why did you off OutOfMemory handling? If you do this then you should process OOM errors yourself in ImageLoadingListener.onLoadingFailed(FailReason.OUT_OF_MEMORY).

My suggestions for you:

• delete .offOutOfMemoryHandling() options in configuration
• delete .discCacheExtraOptions(720, 480, CompressFormat.JPEG, 75) options in configuration
• use .imageScaleType(ImageScaleType.IN_SAMPLE_INT) in display options
• do you really need RoundedBitmapDisplayer? See docs for it, it creates additional bitmap in memory during rounding. Avoid using it if you can.
