Add Author Link in Wallpaper details

[Aksx73]

I tried it by adding required variables in JsonStructure.java/Wallapaper.java/JsonHelper.java/Database.java files And then tried adding an onClick listener to R.id.author_name to get link from json but didn't work.

Would you suggest where I might have gone wrong or what things should I do get it working? And I want to add authorUrl to only one category in my app, So instead of adding a key in JSON format like authorUrl and leaving the value as blank, it should work without adding this key-value where not needed.(i.e just to add one more key-value pair for authorUrl for those photos i want and for those photos i don't want author link if left unwritten the whole key and value ).
