I am using google maps utility library demo code, and change to use Picasso for image load.
My question is as follow capture.
Picasso can't load the image and use the placeholder image
After zoom in and out, Refresh marker. Can load the image
My question same with this Google Map V2 Lazy loading of marker image
But I cannot get help from the answer, I get stuck on Bitmap bitmap = thumbCache.get(url);
I also try the Picasso onSuccess callback, but also get suck on it.
How to refresh the maker icon when download URL image finish? I can use another URL image loader library.
