title: how to save and retrive data from the last run of an android application?
body: <p>I have to create a small android application for my college course work which presents 10 maths problems and take answers from users to calculate the score. </p>
  
  <p>The program is supposed to have a main screen with "new game" button and a "continue" button.</p>
  
  <p>How do I program to save data during the application run and retrieve them from the stored place to continue from that point if the user presses continue button? (what sort of a method I should be looking at for such a task? ) </p>
  
  <p>Thanks in advance. </p>
