As mentioned, I spoke at the Dutch Android User Group at the end of June, with the title "Building, Testing & Deploying Android Apps with Jenkins."
There was a big turnout and I had a great time at the event, including the meal which was a nice change from the stereotypical pizza and beer, i.e. chinese food and beer! :)
The group have since posted a video of my talk, as well as the preceding talk by Eric LaFortune on his projects, ProGuard and DexGuard. I have also uploaded my slides, and a version with brief slide notes.
Thanks again to the organisers for inviting me, and congratulations to them on becoming an official Google Developer Group!
