The preferred way to create a shortcut is through the launcher. Although it is possible for an app to create shortcuts, there is concern that allowing the app to do so may not be desirable due to potentials for abuse. As there is support now for adding shortcuts through the launcher, this app do not need to also support creating them itself.
