Answer 1

I would recommend you to use Gson to deserialize the Json in to object or pojo's and then play with them, also did you check Picasso i'm using that library for a production project and i really like it, cheers.

Answer 2

Just use it like this.

ImageLoader.getInstance().displayImage(urlString, imageView);

If you want to show a loading image while image is loading, use memory cache etc use the DisplayOptions and pass it as a third parameter.

DisplayImageOptions displayOptions = new DisplayImageOptions.Builder()
            .resetViewBeforeLoading(true)
            .imageScaleType(ImageScaleType.EXACTLY)
            .cacheInMemory(true)
            .build();

And use ImageLoader.getInstance().displayImage(urlString, imageView,displayOptions);

Before using this you must initialize the ImageLoader by

ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(getApplicationContext()).build();
    ImageLoader.getInstance().init(config);
