For some reason, Picasso is displaying only 6 images out of 20. It shows the first 6 images and then repeats them. I am getting the images from the web.

Any idea?

Picasso.get().load(response.body().getMediaDetails()

.getSizes().getFull().getSourceUrl())

.fetch(new com.squareup.picasso.Callback() {

  @Override

  public void onSuccess() {}



  @Override

  public void onError(Exception e) {



    // Try again online if cache failed

    Picasso.get()

   .load(response.body().getMediaDetails().getSizes().getFull().getSourceUrl())

    .placeholder(R.drawable.test_img_size)

    .error(R.drawable.test_img_size)

    .into(imageView);



  }

});

So, as some suggest and as you may see, I tried to use glade but it didn't work.
The problem is the same, when the user scrolls up and down the images re-load over and over again. And, some time it only cache 6 images out of 20 (it should cache every image in this way the app will show the image that are in the cache and not fetching in from the web)

If your problem is cache try use the methods skipMemoryCache() and memoryPolicy(MemoryPolicy.NO_CACHE).
