I'm wondering if, with the G1, it's possible to force the network traffic to pass through the Wifi or through the Cell GSM network. I need to force an application to connect through the tower network to get some login information. Is this possible? Anyone have any ideas as to how this would be possible? I'm trying to accomplish this inside an app with the Android SDK (Sorry I wasn't more clear about that originally)
It turns out to be possible using the WifiManager object to disable and then re-enable the connection. You can block it for the duration of a network call if you want to force data over the cell network. I imagine there is a similar GSM network manager out there which will do a similar task for the cell connection.
