. Unfortunately, volley does not provide a default implementation. The introduction of I/O shows a bit of code snippet for Bitmaplrucache, but the volley library itself does not contain any related implementations.The Imagecache interface has two methods, Getbitmap (string url) and Putbitmap (string URL, Bitmap Bitmap). These two methods are straightforward enoug
