title: Warning : Use SwitchCompat from AppCompat or SwitchMaterial from Material library
body: <p>What is the difference between these 2 objects (<code>SwitchCompat</code> and <code>SwitchMaterial</code>)? I have tried them and visually they are identical.</p>
  <p>By the way, why did they remove the <code>Switch</code> class? Do you know which UI element is supposed to replace it in the future?</p>
