<p>Circular <a
  href="https://developer.android.com/guide/practices/ui_guidelines/icon_design_launcher.html">launcher
  icons</a> are supported in Android 7.1.1 and later. Circular launcher icons
are not enabled by default. To use circular icons in your device
implementation, you must edit the <a
  href="{@docRoot}source/add-device.html#use-resource-overlays">resource
  overlay</a> on your device to enable them.</p>

<p>The resource file you are using an overlay on is at:
<code><a
href="https://android.googlesource.com/platform/frameworks/base/+/master/core/res/res/values/config.xml">frameworks/base/core/res/res/values/config.xml</a></code>

<p>To enable circular icons, change the <code>config_useRoundIcon</code>
setting in your overlay file from <code>false</code> to <code>true</code>:</p>

<pre>
&lt;!-- Flag indicating whether round icons should be parsed from the application manifest. --&gt;
&lt;bool name="config_useRoundIcon"&gt;true&lt;/bool&gt;
</pre>
