/**
* This Activity actually handles two stages of a launcher shortcut's life cycle.
*
* 1. Your application offers to provide shortcuts to the launcher. When
* the user installs a shortcut, an activity within your application
* generates the actual shortcut and returns it to the launcher, where it
* is shown to the user as an icon.
*
* 2. Any time the user clicks on an installed shortcut, an intent is sent.
* Typically this would then be handled as necessary by an activity within
* your application.
*
* We handle stage 1 (creating a shortcut) by simply sending back the information (in the form
* of an {@link android.content.Intent} that the launcher will use to create the shortcut.
*
* You can also implement this in an interactive way, by having your activity actually present
* UI for the user to select the specific nature of the shortcut, such as a contact, picture, URL,
* media item, or action.
*
* We handle stage 2 (responding to a shortcut) in this sample by simply displaying the contents
* of the incoming {@link android.content.Intent}.
*
* In a real application, you would probably use the shortcut intent to display specific content
* or start a particular operation.

/**
* 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.
