  <p>I am trying to use this XML as an icon inside my app.</p>
  
  <p>However, for some reason, when I do </p>
  
  <pre><code>&lt;ImageView src="@drawable/icon"/&gt;
  </code></pre>
  
  <p>Running on API 23, My app would immediately crashes on me.</p>
  
  <p>However, on API level 19, the same app runs without any issues.</p>
  
  <p>If I remove that <code>&lt;gradient&gt;</code> tag, the API 23 runs fine as well.</p>
  
  <p>What should I do so that the app in API 23 without any issue?</p>
