Can Volley(Google IO 2013) have level1 LruBitmapImageCache and level2
DiskCache?

Can Android Volley (Google IO 2013) have a Bitmap cache for level one of
cache and also a disk cache for level2. I am not clear on if this is an or
choice or an either/or choice. Also wondering about performance of Disk
cache vs Bitmap cache for images.
