To download multiple image file asynchronously, you should use libraries such as Universal Image Loader, Fresco, Picasso, Glide, Volley Image Loader etc.

My personal favorite is Universal Image Loader

It gives you options to perform certain task like onLoadingStarted, onLoadingFailed, onLoadingComplete, onLoadingCancelled and many more.

This is the best way to load images from server without bothering about asycTask and it works well in list view.

Use HttpURLConnection to obtain an input stream from the URL. Then use BitmapFactory to decode this stream into a bitmap. Keep in mind not to run this code in your main thread. Otherwise it will block anything until the image has been downloaded and decoded.

try {
    URL url = new URL("http://www.samplesite.com/Customer/File/DownloadResource/" + imageID + "?token="+ m_token);
    HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();

    Bitmap mBitmap = BitmapFactory.decodeStream(urlConnection.getInputStream());
    urlConnection.disconnect();

} catch (IOException e) {
    e.printStackTrace();
}
