title: How to keep a variable alive between all fragments
body: <p>My question is this, I have a fragment where I have a menu and select an option that needs to be applied to each fragment that I have.</p>
  
  <p>For example, in my profile fragment I need to enable a certain team for the user, this team will impact in each fragment since if I select for example United States as a team in my profile fragment, I will need to see information about that team in my other fragments.</p>
  
  <p>My question is, is better to do this with a singleton ? so I make an instance of the selection in my profile and then access this in the other fragments.</p>
  
  <p>Is that a good approach or I need to do this in another way?</p>
