Hi Marcus,
Thanks for the interesting post! Looks like you're hacking your way through
Android.
For you information, it became clear Koolu is no longer working on Android fro
the Freerunner. The community has decided to continue working and moved the
project to:
http://groups.google.be/group/android-on-freerunner
and the wiki is on:
http://code.google.com/p/android-on-freerunner/
We've already released our first version and we also have weekly and daily
builds.
The community is welcoming anyone who's willing to contribute in one way or
another. Feel free to join and start your discussions in the new mailing.
Looking forward to see you there.
Niels.
