DataSourceBitmapLoader

@UnstableApi
class DataSourceBitmapLoader : BitmapLoader

A BitmapLoader implementation that uses a DataSource to support fetching images from URIs and BitmapFactory to load them into Bitmap.

Loading tasks are delegated to a ListeningExecutorService defined during construction. If no executor service is passed, all tasks are delegated to a single-thread executor service that is shared between instances of this class.
