###Note

request url :

https://en.wikipedia.org/w/api.php?action=query&prop=pageimages&format=json&piprop=thumbnail&pithumbsize=500&pilimit=50&generator=prefixsearch&gpssearch=<query>

param pilimit in url seems broken as it gets only 10 results for any value
used staggered grid layout manager with 3 columns in ImageSearchActivity. can be configured to suit the needs

 StaggeredGridLayoutManager staggeredGridLayoutManager
                = new StaggeredGridLayoutManager(3, RecyclerView.VERTICAL);// staggered grid with 3 columns

orientation change reloads the page. no specific implementation for orientation change.
