+/**
+ * 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 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.

+     * 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}
