title: How to set the Android Live Wallpaper icon (aka "thumbnail")
body: <p>I built my first Android app. </p>
  
  <p>It is a Live Wallpaper designed for 2.2. </p>
  
  <p>When I press and hold the screen, select <code>Wallpapers</code> and then select <code>Live Wallpapers</code>, my live wallpaper has what looks like a default icon with the name of my live wallpaper overlaid.</p>
  
  <p>How do I set this icon?</p>
  
  <p>My manifest file has an application icon specified as <code>@drawable/icon</code></p>
  
  <p>Update</p>
  
  <p>I think I need to add some info to this question as it poorly describes my problem (sorry).</p>
  
  <ol>
  <li>I have all the <code>res/drawable-[hml]dpi/</code> icons. I named them all <code>icon.png</code>.</li>
  <li>My manifest file contains <code>&lt;application android:label="@string/app_name" android:icon="@drawable/icon"&gt;</code></li>
  <li>I have also tried creating a 48x48 icon in <code>res/drawable/</code> called <code>icon.png</code>.</li>
  <li>I have also tried explicitly adding icons in other manifest tags if they are allowed. eg. service, activity, intent-filter (It should be obvious that I don't know how this manifest file really works, so I was trying anything)</li>
  <li>In <code>Manage Applications</code>, the icon <strong>is displayed correctly</strong>.</li>
  <li>When selecting the Live Wallpaper, the icon is <strong>not displayed correctly</strong>.</li>
  <li><code>mdpi</code> icon is 48x48, <code>ldpi</code> icon is 36x36 and <code>hdpi</code> icon is 72x72</li>
