title: react-native how to customize android elevation shadow
body: <p>Using android-specific style rule, <code>elevation</code>, I get a nasty &quot;halo&quot; effect when using. for example, this image shows <code>elevation: 20</code>:</p>
  <p><img src="https://i.stack.imgur.com/3mVbS.png" alt="bigger &quot;halo&quot; effect" /></p>
  <p>Even a small elevation 1,2, or 3 gives the appearance that the element is &quot;haloed&quot;/has a border (bad)</p>
  <p><img src="https://i.stack.imgur.com/owve4.png" alt="smaller &quot;halo&quot; effect" /></p>
  <p>How can I add more customization to the android-specific shadow to get rid of halo effect. iOS has specific rules like <code>shadowOpactiy</code>, <code>shadowRadius</code>, <code>shadowOffset</code>–but I don't see anything for android.</p>
