Regarding using JNI to bridge to the Nmap binaries, I worked on a project using Nmap and Java. At that time (2009/10) we were advised to avoid JNI because it would require us to continually rebuild binaries to keep current with the Nmap releases. We were advised to use the Runtime.exec() integration so that we would have greater freedom from the Nmap release cycle. After I left that job, I wrote a small open source library called Nmap4j which is on sourceforge.net (nmap4j.sourceforge.net). It's purpose is to enable Java classes to run Nmap and get the output as Java objects. It leverages the XML output of Nmap and uses a SAX parser to convert the data to objects. I've tested it with some large XML files and it performs reasonably well; the largest file I parsed was around 1 million hosts, with 74000 up and the rest down; this took about 70 seconds to parse. If this solution helped those wishing to develop a UI I'd be happy to assist with updates/changes/fixes to the Nmap4j library as needed. I don't know much about Android development but I know it's Java friendly. This library might be helpful if that is case.

I've been talking about it since the end of last summer, but haven't had the time to actually do anything, yet. The previous version I'm aware of installed a pre-compiled Nmap binary and then ran it. I think a better alternative is to leverage the Android NDK -- but other than getting the NDK on my machine, I haven't really looked into the viability of this. I've been given a 'green light' to do this as my project for one of my classes this semester, so maybe I'll finally get something done, but it won't be very robust and I plan to ignore the 'Androids don't have root access and can't make raw packets' issue.
Nmap is ported on Android, so there's not too much left job to do on NDK side. The binary works as root user as well as normal user. Of course, if you don't have root access, you'll be limited what type of scanning you can perform.
Something that was suggested to me last year, is that simply porting Nmap to Android probably isn't a big enough project for GSoC (isn't the target ~1000 hours?). My suggestion would be to think of ways to extend or enhance it, as well. Hopefully by May I'll be able to provide something for someone to build on, or at least give an example of one implementation alternative.
My personal opinion (not Nmap official!) about further Android advancement and what can be done as SoC (i.e. they are big enough): - develop official Nmap Android frontend to Nmap binary. In this case Android GUI would execute Nmap binary and parse results. Maybe John Holden is willing to donate some of his interface code? - proceed with "librarization" of Nmap: i.e. make library of nmap. I think I saw this already on Nmap Gsoc page, but don't know why nobody pick that. This would help in other efforts like rainmap/zenmap beside Android. And we would skip this nasty bug as well: http://www.crystax.net/trac/ticket/1 (As this bug is only present with binaries(!) and not libraries(!)) In this case, Java GUI would call nmap through library using Java Native Interface (JNI).
