  • *
* * If you use a simple drawable resource, note that you must wrapper it using * {@link android.content.Intent.ShortcutIconResource}, as shown below.

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. * @param profile */ private void setupShortcut(VpnProfile profile) { // First, set up the shortcut intent.
