If you deleted the host routes (started a secondary network like mms, supl of hipri and then ended it) you would lose the host route to the default gateway. Then if you needed to re-add the default gateway route (lost the connection and removed the default route and then re-established) you couldn't - can't add a gateway that isn't routable apparently. This happens if you are in a video chat and lose your connection without losing the interface (PPP keeps it up for a bit). Fixed it by having addDefaultRoute first add a hsot route for the gateway before adding the default route. This allows the default add to succeed. bug:3490353 Change-Id: I415e7319832e6456f8757b14c4f79f098a08839b
