Unable to parse image from Json to listview in android

Question

I am trying to parse the images and text from url to list view.

I succesfully parse names but unable to parse Images. I follow these links....

I am getting bit map value null in image loader class..

I copied the MemoryCache and File Cache classes from the below links... Is there any mistake in my code?

My Json is: http://192.185.159.159/~charmmar/raj_spice/webservices/index.php?action=products Is any problem for image parsing if json is large?

2. http://luchfilip.wordpress.com/2014/02/25/android-how-to-parse-json-and-show-images-and-texts-in-a-listview/comment-page-1/
3. http://www.androidhive.info/2014/07/android-custom-listview-with-image-and-text-using-volley/

in these links all contained ImageLoader, FileCache, MemoryCache classes but I am unable to parse images... is any special library needed for this?
