title: Android Studio: what's the best/simplest method to return the amount of time that has passed since a button was pressed?
body: <p>Say I were to press a button twice, and I wanted a returned value of the amount of time between the two presses? Most sources tell me to use a chronometer but I don't want the time to be displayed anywhere on the app.</p>
  
  <p>I apologize if this is a simple problem, I am relatively new to coding.</p>
