Black Background on image loaded with univerisal image loader

问题

As shown below. The first image is the default image linked at http://goldentrail.towardstech.com/assets/images/membersimage/buttons/eat.png. while the second image below it is the image that is loaded using uil

This is the imageloader configuration

    File cacheDir = StorageUtils.getCacheDirectory(context);
    ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context)
            .memoryCacheExtraOptions(480, 800) // default = device screen dimensions
            .discCacheExtraOptions(480, 800, CompressFormat.JPEG, 75)
            .taskExecutor(AsyncTask.THREAD_POOL_EXECUTOR)
            .taskExecutorForCachedImages(AsyncTask.THREAD_POOL_EXECUTOR)
            .threadPoolSize(3) // default
            .threadPriority(Thread.NORM_PRIORITY - 1) // default
            .tasksProcessingOrder(QueueProcessingType.FIFO) // default
            .denyCacheImageMultipleSizesInMemory()
            .memoryCache(new LruMemoryCache(2 * 1024 * 1024))
            .memoryCacheSize(2 * 1024 * 1024)
            .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
            .enableLogging()
            .build();

this is the displayoptions

DisplayImageOptions options = new DisplayImageOptions.Builder()
    .bitmapConfig(Bitmap.Config.ARGB_8888) // default
    .cacheInMemory()
    .cacheOnDisc()

    .build();

Did you see comment in Readme:

DON'T COPY THIS CODE TO YOUR PROJECT! This is just example of ALL options using.

Don't use .discCacheExtraOptions(480, 800, CompressFormat.JPEG, 75). Your images saved in disc cache as JPEG files which can't have transparent background.

Try to use android-query. This API helps with images and some others works with android.
