title: Icon and left arrow / burger with support action bar
body: <p>I am starting to use the App Compat library in my app and I am struggling with the action bar icon. My test activity is as simple as </p>
  
  <pre><code>[Activity(Label = "MyLabel", Theme = "@style/Theme.AppCompat.Light", Icon = "@drawable/ic_launcher", MainLauncher = true)]
  public class MyTestActivity : ActionBarActivity
  {
  
      protected override void OnCreate(Bundle savedInstanceState)
      {
          base.OnCreate(savedInstanceState);
          SupportActionBar.Title = "My Title";
          SupportActionBar.SetIcon(Resource.Drawable.Icon);
          SupportActionBar.SetDisplayHomeAsUpEnabled(true);
          SupportActionBar.SetHomeButtonEnabled(true);
      }
  }
  </code></pre>
  
  <p>I am expecting the output as follows:</p>
  
  <p><a href="https://i.stack.imgur.com/pRjK2.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/pRjK2.png" alt="Action bar with Icon"></a></p>
  
  <p>However, with the current 22.2.0.0 version of the app compat library, the action bar looks like this:</p>
  
  <p><a href="https://i.stack.imgur.com/7cIqV.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/7cIqV.png" alt="Actionbar without icon"></a></p>
  
  <p>Interestingly, when using the 7.18.0 version of Xamarin's v7 App Compat component, the output is as expected (first image) (but that doesn't give me the new features in 22.2.0.0).</p>
  
  <p>Is there any way to achieve the expected (first) output with 22.2.0.0?</p>
  
  <p>Any solution (Xamarin C# or simple Java) would be great!</p>
