Push notification icon in Cordova Android : <p>I'm using <a href="https://github.com/phonegap/phonegap-plugin-push/" rel="noreferrer">Phonegap Push Plugin</a> and when a push notification is shown in the notification area, the icon is just a white square. I would like it to show <code>star.png</code> instead. I tried following <a href="https://github.com/phonegap/phonegap-plugin-push/blob/master/docs/PAYLOAD.md#images" rel="noreferrer">the documentation</a> as follows:</p>

<p>I put <code>star.png</code> in <code>www/images</code>, and added the following lines to <code>config.xml</code></p>

<pre><code>&lt;platform name="android"&gt;
  &lt;resource-file src="www/images/star.png" target="res/drawable-xhdpi/star.png" /&gt;
  &lt;resource-file src="www/images/star.png" target="res/drawable-hdpi/star.png" /&gt;
  &lt;resource-file src="www/images/star.png" target="res/drawable-mdpi/star.png" /&gt;
  &lt;resource-file src="www/images/star.png" target="res/drawable-ldpi/star.png" /&gt;
&lt;/platform&gt;
</code></pre>

<p>(I understand that I should use different resolutions, but I'm just trying to get it working now.)</p>

<p>Then when I initialize the plugin, I use:</p>

<pre><code>let push = PushNotification.init({
    android: { senderID: globalData.firebaseSenderID, icon: 'star.png', iconColor: 'blue' },
    ios: {}
});
</code></pre>

<p>I also tried <code>icon: 'star'</code>. 
However the white square persists. How can I get this to work?</p>

<p>Using cordova@8.0.0 &amp; cordova-android@6.4.0.</p>
