Answer 1

You can use restfb to parse Json-Objects:

JsonObject obj = new JsonObject(SERVER_RESPONSE);
try {
     String pictureURL = obj.getString("picture");
    }
catch(JsonException e) {
       // key 'picture' not found
       e.printStackTrace();
}

Answer 2

Could it be that RestFB isn't up to date in sense how Graph API returns (some objects) inside "data" object?

I managed to work-around with this custom class:

public class DataPictureHolder {
    @Facebook("data")
    public ProfilePictureSource picture;
}

You know how to parse the response?

If yes, just get the URL of the image, open a URLConnection and do a getInputStream() (the code for this is in this SO answer).

With the InputStream, you can save to a file or send it to the client.
