Handling an Intent without an Activity UI

 Hey list,

I've searched for a few hours for a solution to this, so hopefully
this isn't a repost :s

I'm setting a shortcut on the Home screen which raises an Intent to my
application - the problem is that I don't want to show my app, just
run a little code and display a Toast notification.

This must be possible - I just can't work out how.. Once I'm handling
the shortcut Intent in onCreate() the UI has initialised and I get a
little screen flicker if I then run my code and finish().

Thanks for any input!

Handling an Intent without an Activity UI

 I'm thinking I might need to write a service to handle my shortcut's
Intent. The main application could then raise a similar Intent to the
service to provide the same functionality whilst in the application.

Comments anyone?

Handling an Intent without an Activity UI

I do not know if you can create home screen shortcuts that send
broadcast Intents. If you can, then register a BroadcastReceiver in your
manifest to catch some custom action, and set up your shortcut to send a
broadcast Intent with that action. If what you need to do takes only a
few seconds, you can do the work within the BroadcastReceiver;
otherwise, have the receiver call startService() to trigger some
IntentService to do the real work.

This seems terribly complex, compared to just giving the user a real
activity to work with, but, hey, it's your app... :-)

 You're right it does sound terribly complex. Ill report back on my
findings for anyone else who has a similar problem.

Thanks for your input, Mark.
