Android Studio: how to load bitmap as Marker using picasso or fresco?

Question

Android

Good afternoon.
There is a common error in picasso when working with target: onBitmapLoaded does not fire.
How else can you use the loaded bitmap without attaching it to the imageView?
When working with fresco, I used the image loading method via ImagePipeline and dataSource.subscribe(new BaseBitmapDataSubscriber()), CallerThreadExecutor.getInstance());
, but without success
How to load the bitmap not in the imageView, but for further use in the code?
Thanks

Answer 1

Well frescolib makes it pretty easy to do this. Just read the docs: frescolib.org/docs/using-image-pipeline.html

Answer 2

While I made a crutch on Picasso using transform:

ImageView imageview = new ImageView(MainActivity.this);

                Picasso.with(getApplication())
                        .load(url)
                        .transform(new CropSquareTransformation())
                        .into(imageview);



public class CropSquareTransformation implements Transformation {

        @Override public Bitmap transform(Bitmap source) {

            Log.w("MY", "Bitmap transform(Bitmap source)");

            int size = Math.min(source.getWidth(), source.getHeight());
            int x = (source.getWidth() - size) / 2;
            int y = (source.getHeight() - size) / 2;

            Bitmap result = Bitmap.createBitmap(source, x, y, size, size);

            MY_FUNCTION(result);

            if (result != source) {
                source.recycle();
            }



            return result;
        }

        @Override public String key() { return "square()"; }
    }

Not quite beautiful, I'm using an imageview that I don't need.
How to optimize?
