title: How to download images in background in Android GridView?
body: <p>I have this GridView in android in which I display some images that should be downloaded on-demand. The problem is taht the program waits upon every image request to be downloaded completely and then moves on to the next image thus making the loading very slow. I just want to know how should I move the image downloading to the background and display the image when it's ready.<br>
  I think I should use AsyncTask for this purpose but I have no idea how should I do this?</p>
