Change the hint test of group address from ff13::... to ff12::...
Change the hint test of group address from ff13::... to ff12::...

If the group address starts from ff13, the android system choose a source address as grobal, e.g. 2001:... . This may cause some issues on some environment. It is safer to choose ff12::... as group address for experiment.
