I'm a newbie, and I find Titanuim very good.
Can I use Titanuim to develop an app that will not run in the background (and consume the device battery), but an app that I'll be able to "wake/start" it remotely (with some params), base on server events.
If I can't do the above, what is the alternative, can I run it in the background with minimum footprint.
Are you referring to Apple iphone app?
If so, 3rd party apps almost always run on the foreground.. I think..
Currently Apple doesnt accept third-party applications running in background.
The closest that can be done (from what I know) is the push notifications.
