android - How to let Picasso check the cached file on disk at provided path? -


we know picasso first checks memory cache, disk cache , in end downloads file if can't find it.

my aim "tell" picasso, when needs file disk, find , if not exist there, download , save @ path.

the reason want ensure can make use of downloaded file again anywhere else in app if need. way, if file has been downloaded part of app, picasso not download again , use straight away. otherwise, picasso download , else not have download again , use it.

is possible tell picasso , download (if needed) file @ path developer provide?

any suggestions how achieve it?
