title: Android cannot excludeFromRecents if it's in the app is running
body: <p>I have added <code>android:excludeFromRecents</code> into <code>&lt;activity/&gt;</code> to hide my app from <a href="https://developer.android.com/guide/components/activities/recents#adding" rel="nofollow noreferrer">Recents Screen</a>. But it's not working if I open Recents Screen when the app is <strong>running</strong>.</p>
  <p>Here is details how I've tested:</p>
  <p><em>Case 1:</em> Open my app -&gt; Go back to main screen -&gt; Click square button (Open Recents Screen) -&gt; Do not see my app <strong>=&gt; Its working fine</strong></p>
  <p><em>Case 2:</em> Open my app -&gt; Click square button -&gt; My app is there <strong>=&gt; It's not working</strong></p>
  <p>My question is:</p>
  <ul>
  <li>Why this happen?</li>
  <li>Is there any way to completely hide my app from Recents Screen? (Note: I don't want to kill/finish the app, only hide)</li>
  </ul>
