     * <ul>
     * <li>{@link android.content.Intent#EXTRA_SHORTCUT_INTENT} The shortcut intent.</li>
     * <li>{@link android.content.Intent#EXTRA_SHORTCUT_NAME} The text that will be displayed with

     * <li>{@link android.content.Intent#EXTRA_SHORTCUT_ICON} The shortcut's icon, if provided as a
     * bitmap, <i>or</i> {@link android.content.Intent#EXTRA_SHORTCUT_ICON_RESOURCE} if provided as
     * a drawable resource.</li>
     * </ul>
     * 
     * If you use a simple drawable resource, note that you must wrapper it using
     * {@link android.content.Intent.ShortcutIconResource}, as shown below.  This is required so
     * that the launcher can access resources that are stored in your application's .apk file.  If 
     * you return a bitmap, such as a thumbnail, you can simply put the bitmap into the extras 
     * bundle using {@link android.content.Intent#EXTRA_SHORTCUT_ICON}.
     * 
     * The shortcut intent can be any intent that you wish the launcher to send, when the user 
     * clicks on the shortcut.  Typically this will be {@link android.content.Intent#ACTION_VIEW} 
     * with an appropriate Uri for your content, but any Intent will work here as long as it 
     * triggers the desired action within your Activity.
