If you mean 3rd party software you could a) tell your employees that using other apps on the device is simply not allowed. b) make your app check list of installed apps and check if there's anything additional check if it uses networking permission. c) root the phone and setup i.e. iptables so only access to your server is allowed. > for?

Most devices in network have to have IP address to make use of it. So is mobile phones. I however would rather check if using 'polling' is not a better solution as 'pushing' (to device) may be problematic due to carrier setup. > Or should I get small text plan and use that for this specific functionality? > Can I receive text message in my Yes you can recive incoming text messages in your app -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
