My thanks to:
...because openSuse runs on my machine and for android programing I use java within the eclipse development environment. Thank you also to Joomla for making homepages easy to create (Joomla use MySql and PHP). Thank you to phoca for providing the webtemplate. For icon creation I used gimp.
And anybody who works as an opensource developer knows that this list should be longer - but then I have no time for android programing anymore :-)
