Wow Malkom, thx for that quick reply... When I wrote you/this forum a couple of months ago you also wrote back soon and gave good pointers too... excellent 
What you said about the resolution should work with my app... I think this will be an excellent way to do it. I will look into the solar app. I think my first step will be to make a couple of pages with a few images and try it on my samsung galaxy s2 and get a hold on a nice 
tablet... Then (and this will be the hardest task) I will try to implement a sort of database .... and hope simple command will work with it (if then functions).
thanks again Malkom and if there is or if there will be any apps made with HAC that uses the database structure I need (or looks like it) I will be really interested in any help (via source code 
if your willig to share it with me). Even if it's only a step in a certain direction I will be very greatfull.

Hi Jeroen
Looking at your app from a few directions is a good plan and helps you get around any limitations or problems.
Its also possible to set up a tablet type emulator. For example, the Android SDK has options to set up Galaxy Tab, Motorola Xoom emulators and a few others as well for trying different screen resolutions etc. If your app doesn't use animation then an emulator is a good option until you get another tablet.
HAC doesn't yet support the Android MySQL database but its high priority for us as many people have asked for it.
It sounds like you might need such a relational database but if not there is also the traditional flat file model where you store your keys and their attributes in arrays then save it in a file, or several files.
Our HyperNext Studio software development system has an example project with some bits of for more a book database that uses arrays. If you are in a hurry then you could look at that until our MySQL is ready.
Anyhow, I'll try to get an example project put together and posted.
Malkom
