Question

I need to develop an application that will check whether the phone is in roaming. If it’s in roaming then the application should block internet for all applications except several from white list. In non-roaming mode it should allow all requests. There should be no way for user to kill or suspend the application or turn internet on.
I’m not familiar with android much so I really don’t know whether it possible to implement without modification of OS. Is there any way to do this?

DroidWall – Android Firewall is a front-end application for the powerful iptables Linux firewall. It allows you to restrict which applications are permitted to access your data networks (2G/3G and/or Wi-Fi).
