How to clear cache and Reload Image in Picasso?

Question

I am using Picasso to load image in my application but i facing a issue that my image URL is same but image is changing from backend calling the same URL but Picasso loading the same image saved in its cache. Now i want to clear the cache for that Image and reload the image again.

What i have tried i searched on SO find that we can use picasso.invalidate(fileName); or memoryPolicy(MemoryPolicy.NO_CACHE) but i am getting the error message in code

Can't reslove method invalidate

Can't reslove method memoryPolicy

dependency for picasso in gradle :

compile 'com.squareup.picasso:picasso:2.4.0'

Answer 1

Try to use this.

 Picasso.with(context).invalidate(url); 
 Picasso.with(context).load(url).networkPolicy(NetworkPolicy.NO_CACHE).memoryPolicy(MemoryPolicy.NO_CACHE); 

compile 'com.squareup.picasso:picasso:2.5.2'
