Do I use Activities or Fragments?

Question

I’m with a project to develop a guide app for games that will show images through a server and the guide will be pdfs files downloaded and opened by the app.

The flow would be:

Console list (Listview) -> Game list (Gridview) -> Screen where the game guide shows.

However the amount of games and guides is large, I wondered if it would be possible to only Activities and only send information to among them to appear the data as per the user’s selection.

Regardless of the answer, please detail the answer, if possible with example.

Another question is which would be the best server to store images and pdfs files?

Thank you.

Answer 1

The correct one was to use activities but with recyclerview instead of Gridview.

The project went all right.
