title: How to add button icons to ActionBar in Nativescript?
body: <p><strong>Hi there people!</strong></p>
  
  <p>I'm trying to add a hamburger menu icon to the ActionBar in my Nativescript app that would trigger a side drawer, but I can't get to add that menu icon.</p>
  
  <p>This is the <a href="https://docs.nativescript.org/ui/action-bar#creating-slidedrawer-button" rel="nofollow noreferrer">official documentation on the matter</a>;</p>
  
  <p>And this is my <code>.xml</code> code so far:</p>
  
  <pre><code>&lt;dpg:DrawerPage loaded="pageLoaded" navigatedTo="onNavigatingTo"  
  xmlns:dpg="nativescript-telerik-ui/sidedrawer/drawerpage"
  xmlns:drawer="nativescript-telerik-ui/sidedrawer"
  xmlns:sdc="views/side-drawer-content"
  xmlns="http://www.nativescript.org/tns.xsd"&gt;
  &lt;navigation.actionBar&gt;
    &lt;ActionBar title="Drawer Over Navigation"&gt;
      &lt;android&gt;
        &lt;NavigationButton icon="res://ic_menu" tap="toggleDrawer" /&gt;
      &lt;/android&gt;
      &lt;ios&gt;
        &lt;ActionItem icon="res://ic_menu" ios.position="left" tap="toggleDrawer" /&gt;
      &lt;/ios&gt;
    &lt;/ActionBar&gt;
  &lt;/navigation.actionBar&gt;
  
  &lt;dpg:DrawerPage.sideDrawer&gt;
  &lt;drawer:RadSideDrawer id="drawer"&gt;
    &lt;drawer:RadSideDrawer.drawerContent&gt;
      &lt;sdc:side-drawer-content /&gt;
    &lt;/drawer:RadSideDrawer.drawerContent&gt;
  &lt;/drawer:RadSideDrawer&gt; 
  &lt;/dpg:DrawerPage.sideDrawer&gt;
  
  &lt;StackLayout cssClass="mainContent"&gt;
      &lt;Label text="{{ exampleText }}" textWrap="true" cssClass="drawerContentText"/&gt;
      &lt;Button text="Toggle Drawer" tap="toggleDrawer" icon="res://ic_menu" /&gt;
  &lt;/StackLayout&gt;
  &lt;/dpg:DrawerPage&gt;
  </code></pre>
  
  <p>I think the relevant part is here, but I can't see what could be my mistake.</p>
  
  <pre><code>&lt;ActionBar title="Drawer Over Navigation"&gt;
      &lt;android&gt;
        &lt;NavigationButton icon="res://ic_menu" tap="toggleDrawer" /&gt;
      &lt;/android&gt;
      &lt;ios&gt;
        &lt;ActionItem icon="res://ic_menu" ios.position="left" tap="toggleDrawer" /&gt;
      &lt;/ios&gt;
  &lt;/ActionBar&gt;
  </code></pre>
  
  <p>Please, tell me any additional information I could provide to make this issue clearer.</p>
