How to determine if a home screen shortcut exists?
<p>Is there a way to determine whether a particular home screen shortcut
exists? </p>

<p>My application installs a shortcut on the home screen at device
startup time under certain conditions and I don't want duplicate
shortcuts to appear. I also don't want Toast messages appearing saying
"Shortcut created" or "Shortcut already exists" every single time the
device boots.  I've found an undocumented Intent Extra called
EXTRA_SHORTCUT_DUPLICATE which will prevent duplicate shortcuts from
being installed but the Launcher still displays the "Shortcut already
exists" Toast message.  I'd rather not rely on this undocumented
Intent Extra if there is a supported technique for this.</p>
