title: How one can save state of a game and retrieve back?
body: <p>I'm unsure on how to save the game state of my game that I'm developing. Whenever back boutton is pressed I need to save the actual state (such game board with all placed tokens, etc...). All of these are lost whenever the back button is pressed. Should I save a instance, object containing all the game informations? How? Or should I save all the relative informationsin an SQLite data base? And retrieve them when the activity is launched?</p>
  
  <p>I have created two buttons: one for New game and the other that resumes  a saved game. For now only the one that launches new game works.</p>
  
  <p>What is the best practice to achieve this? Please provide some exemple. Thanks</p>
  
  <p>PS: I Still a learner so please bear with me.</p>
