I've had a serious look at this, but it looks like the Android NDK doesn't 
provide ipv6 support. Or at any rate, not in a form Python can cope with.

When I enable ipv6, I get the following error:

/home/robbie/python-for-android/python-build/python/jni/../../python-src/Modules
/getaddrinfo.c:433: error: 'struct in6_addr' has no member named 's6_addr8'

I'm open to suggestions, though.

The Patch [PATCH] python: enabled IPv6 socket support from 
http://permalink.gmane.org/gmane.comp.lib.uclibc.buildroot/40455 will solve the 
premature exit of the 'configure.sh' script when cross-compiling for android. 
The 'configure.sh' script echo before exit the message:
""" 'Fatal: You must get working getaddrinfo() function.'
'or you can specify "--disable-ipv6"'. """

After compilation the above step that will reproduce the problem return 'true'

Does "s = socket.socket(socket.AF_INET6, socket.SOCK_DGRAM)" succeed ?

You need to rebuild Python with ipv6 enabled, see patch for Python 2.7: 
http://code.google.com/p/android-python27/source/browse/python-build/patch/Pytho
n-2.7.2-enable_ipv6.patch

Ok thanks. Is there no APK Package yet?
If you have python could you provide it somewhere?

You can build your own APK following instructions there: 
http://code.google.com/p/android-python27/ (Python 2.7 with ipv6 would be 
embeded)

Ah ok these are ust zip packages.
Is it statically linked?
So you could just provide the binary.

What if in pyconfig.h you change #undef ENABLE_IPV6 to #define ENABLE_IPV6 1 ?
