In order to see an icon in the live wallpaper menu, you need to set
the android:thumbnail attribute for the applications <Wallpaper> tag.
This will normally be found in the XML file corresponding to the class
that extends WallpaperService.
Looking at the CubeLiveWallpaper sample application provided with the
SDK, we see this tag to be located in cube1.xml and cube2.xml. A
modified version below displays the icon thumb.png located in
res/drawable and provides a description defined in strings.xml
<wallpaper
xmlns:android="http://schemas.android.com/apk/res/android";
android:thumbnail="@drawable/thumb"
android:description="@string/description"
android:settingsActivity="com.example.android.livecubes.cube2.CubeWallpaper2Settings"
/>
