There is a server and an android client, the question is: how to properly upload photos from the server to RecyclerView (or ListView). While using Picasso with write to the cache, but it is doubtful that this is the correct and competent way. I do not find any fresh, good articles. Maybe use Picasso, but without the cache, and always download from the server? The application for the delivery of food, you need to upload photos of dishes. In applications such as DeliveryClub or ZakaZaka, the hash is clear, but images are loaded instantly. How is this implemented in them?

  • And how do you know that they do not use the cache? .. From the data about the application? .. They can also cache pictures into another folder, even to a memory card. And then the cache is there, and you can delete it only through the file manager. - Yuriy SPb ♦

    Do not hesitate, this is the correct and competent way. Do not store pictures in the cache makes sense only if they are very often updated or very rarely shown in the application more than once. - xkor
  • @ ЮрийСПб Yes, from the application data. I wouldn’t have guessed that, I’d like to find out exactly how they are implemented. - Sam
  • @Sam you can find out if you look at their source or ask the creators. But in any case, xlor said everything correctly about the pictures and the cache. Well, check if there are any folders for these applications on the device. - Yuriy SPb ♦
