I'm implementing an Android gallery widget. I'm asking how to lazy (i.e. in a separate thread) load images from the web and persistently cache them? So that on the next run I have the cached images locally available...

    You have to use Picasso. 

    it's easy to use

    downlod latest jar from  http://square.github.io/picasso/

    simply load image used below code

    Picasso.with(context)
               .load(url)
               .placeholder(R.drawable.placeholder)
               .resize(imgWidth, imgHeight)
               .centerCrop()
               .into(image);
