I am trying to learn from Android source on Data-Wifi automatic switch.
The closest I can get is DataCommand and WifiCommand, they seem to switch network preference (through ConnectivityManager), by which I suppose can switch active interface. But I cannot find where these commands are actually used.
Can any one has experience in Android framework point for me where to look at?
I know this might be the wrong place to ask source code question, but any help is appreciated.
