public class BitmapDrawableResource extends DrawableResource<BitmapDrawable> implements Initializable
Resource
that wraps an
BitmapDrawable
This class ensures that every call to DrawableResource.get()
} always returns a new
BitmapDrawable
to avoid rendering issues if used in multiple
views and is also responsible for returning the underlying Bitmap
to the
given BitmapPool
when the resource is
recycled.
