The link that you provided is good for understanding what is convertView, asyncTask etc.I dont think doing View v = super.getView(position, convertView, parent); would work. If you want to recycle views you should do if(convertView != null){ myView = convertView} else{ inflate(myView)};

About AsyncTask that's right its different in different APIS but when you use execute() for old API and executeOnExecutor on the new one - I think everything is fine. You should pass URI and ImageView to your AsyncTask. Here you could have problem with convertView that it appears in a new row with AsyncTask working on it's image. You can hold for example hashmap of ImageView-AsyncTask and cancel these which are not valid any more.
