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