title: The name of popup window onclick of an Android app
body: <p>I would like to know what is the name of a UI component: it’s like <a href="https://imgur.com/gallery/KYudbf4" rel="nofollow noreferrer">this</a> in the CITIZEN app , when we click on the pin on the map, a small card would pop up in the same activity (the users are not led to the other activity but remain in the same one).</p>
  <p>I would like to know what this “small card” is professionally called in UI, so that I can google how to implement it in my Android app.</p>
