How to clear cache in picasso?

I am developing an android app.In that app, the server stores the images that is to be displayed in imageView of listview. I use picasso to get image from the server and display in imageview. Though I had uploaded new images in server, only old images are being displayed again. I suspect this is due to cache in picasso. I used 3 methods to prevent cache:

Picasso.with(getActivity()).load(data.get(pos).getFeed_thumb_image()).skipMemoryCache().into(image);

Picasso.with(getActivity()).load(data.get(pos).getFeed_thumb_image()).memoryPolicy(MemoryPolicy.NO_CACHE).into(image);

Picasso.with(context).invalidate(imagePath);

But in no result. How can I clear cache in picasso for particular url?

Try load url with variable like time now: Calendar urlvar = Calendar.getInstance(); int seconds = urlvar.get(Calendar.SECOND);

Then load your url by adding to string: ?urlvar so the final loaded url will be for example example.com/m.png?date it will be cashed but next load the date is changed so the url will change so will not load from cash. Hope ot work

This is going to be implemented in the future, but see the post of Jake Wharton:

JakeWharton commented on 11 Dec 2014 Current best candidate:

picasso.load('http://example.com/')
  .cachePolicy(NO_CACHE, NO_STORE)
  .networkPolicy(NO_CACHE, NO_STORE, OFFLINE)
  .into(imageView);

enum MemoryPolicy {
  NO_CACHE, NO_STORE
}
enum NetworkPolicy {
  NO_CACHE, NO_STORE, OFFLINE
}

This will be what's implemented unless anyone has other thoughts.
