Android does stuff with the networking stack so that it can live in multiple
provider domains. So the default route (if it exists) often lives in a
alternate routing table.

you didn't post details, but..
if you tcpdump on your Ubuntu side, you'll probably see that AOSP side has
picked some other IP address as the source. If you really want to fix that,
then add a route back to the ppp0 device on the ubuntu side, but probably you
just need to make sure that the Android side always uses the right source IP.
