	/**
	 * This function creates a shortcut and returns it to the caller.  There are actually two
	 * intents that you will send back.
	 * <p>
	 * The first intent serves as a container for the shortcut and is returned to the launcher by
	 * setResult().  This intent must contain three fields:
	 * <p>
	 * <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
	 * the shortcut.</li>
	 * <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>
	 * <p>
	 * 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}.
	 * <p>
	 * 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.
