I just finished up the TDC - Tactel US Developer Corner web site and it's online here; now officially launced:
There are 45 tutorials planned split into 4 sections including Android essentials, math & algorithms, Android OpenGL ES, Android Quake / Auriga3D
Tutorial content is forthcoming and once I finish a few more announcements today about the site I'll be working on them full time and plan to release them consistently over the next 3 months. The general idea is to be able to guide someone who is already generally familiar with Java programming through the necessary Android essentials then through some math and OpenGL ES 1.X API topics leading up to implementation of a 3D FPS engine that loads Quake assets. I'm considering releasing Auriga3D w/ Quake 3 asset loading support instead of Q1 too. All source code available by the MIT license. We actually want as many people as possible to run with the code and create really awesome apps for Android.
Beyond that, I put a bit of time into developing the site and added some neat community oriented features w/ more forthcoming. You can log in using several different 3rd party services like your Google account, Facebook, Myspace, Twitter, and a bunch more automatically creating a profile from the account you chose. It would be great to get some eyes on the site. Check it out if you guys can and add it to your RSS reader or follow on Twitter to hear about when new tutorial content becomes available.
Thanks for checking it out!!
