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. */ public class LaunchVPN extends Activity { public static final String EXTRA_KEY = "de.blinkt.openvpn.shortcutProfileUUID";
