For Android version 2.2 or better the navigator.connection object already
exists. If this case we should immediately fire the onPhoneGapConnectionReady
event so we don't tie up the 'deviceready' event.
Adding a new object to navigator called 'connection'. Users can query the
connection object to find out what type of network, if any, the device is
connected to. The connection object will be updated each time there is a
connectivity change on the device.
