title: How can I put the first activity on pause when switching from the first activity to the second one and not destroy first activity?
body: <p>I have the <strong>first activity</strong> and a button on it , when I click the button , I go to the <strong>second activity</strong>. And when I moved / am on the second activity I would like the first activity not to be destroyed but to pause(FirstActivity.Pause). Tell me if there are ways to implement this ? </p>
  
  <p>I want to implement this so that the data from the first activity is not deleted.</p>
  
  <p>Thanks!</p>
